In world first, Chile to ban single-use F&B products over three years

In May 2021, Chile announced a legislative ban on single-use products in the food and beverage industry to take effect over the next three years.Similar bans in other countries and cities also address the crux of the plastic pollution problem — the disposable culture — but Chile’s ban extends to other materials too, including cardboard and poly-coated paper.In the lobbying process, the Chilean plastics association raised some concerns about the intricacies of the ban, but said it was ultimately “satisfied with the outcome.” New legislation passed by the Chilean government in May 2021 aims to rid the nation of all single-use products in the food and beverage industry, including plastics, within three years. This is the first national-level legislation in the world to implement a ban on single-use F&B products, such as those made of plastic, cardboard and other materials, as opposed to targeting single-use plastics alone. It also follows Chile’s 2019 ban on plastic bags, which received some criticism for people swapping out disposable plastic bags for disposable paper ones, or overcollecting reusable bags.
Chile produces nearly 1 million metric tons of plastic trash a year, but recycles just 8.5% of it, according to a 2019 report by InvestChile. In comparison, Europe has a recycling rate of about 30%, according to another 2019 report by Hamburg-based research firm Statista.
The new legislation will significantly reduce Chile’s plastic waste while boosting the nation’s plastic recycling rates, experts say. This law is projected to eliminate an estimated 23,000 metric tons of single-use plastic pollution annually — the weight equivalent of 116 blue whales, according to a 2020 report by the NGO Oceana Chile.
“The plastic industry now realizes that we are not targeting plastics specifically, but the unnecessary use of single-use items,” Javiera Calisto, legal director of Oceana Chile, told Mongabay. Oceana Chile and its partner organizations were the teams responsible for the proposal and lobbying of this new bill over the past three years.
The law aims to reduce waste generation in three key ways: eliminating single-use products in the food and beverage industry, certifying plastic products, and regulating the use and composition of disposable plastic bottles.
“The law establishes different terms for the respective obligations to come into force. Since we’re making important changes, it was very important to be realistic,” Calisto said.

According to Oceana, plastic tableware such as straws, cutlery and stirrers will be banned from all eating establishments six months after the law is enacted. Other changes will have up to three years to come fully into force. This includes a requirement that at least 30% of bottled drinks in supermarkets must come in reusable bottles.
Other places in the world have taken similar action as Chile by taking a “hard measure” approach to eliminating single-use plastics. For instance, New York City, California, Hawai‘i, Kenya and the European Union have all banned single-use plastic bags in recent years.
As of July 2018, 127 out of 192 countries have adopted full or partial bans against plastic bags, while 57 countries have imposed a plastic bag tax on either the producer or consumer at the national level, according to the United Nations Environmental Programme.
But these legislations are far from perfect. Common criticisms against increasingly popular plastic bans include the fact that they harm poor nations and people the most, and merely encourage the uptake of equally harmful alternatives. This was the case when Chileans began amassing huge amounts of reusable bags following the countrywide ban on plastic bags in 2019.
Chile’s newest law will apply to single-use products including plastic utensils, poly-coated paper cups, disposable cardboard trays and single-use chopsticks, as opposed to single-use plastics alone. Single-use products have been defined as any F&B utensil that is not “used by the establishment on multiple occasions in accordance to their design,” regardless of the material they’re made of.

Change in the works
Under this legislation, restaurants that fail to comply can be fined up to around 327,000 Chilean pesos ($360) per product, and supermarkets can be fined 1.3 million pesos ($1,435) per reported case.
Some establishments have already made the switch to reusables. At Mallplaza Egaña, a shopping mall, reusable cutlery and utensils such as including plates, cups and stirrers have replaced all single-use plastics in its food gardens.
Antonio Braghetto, operations manager of the Mallplaza mall franchise in Chile, told Mongabay in an email that the legislations imposed in Chile in recent years have helped “mobilize organizations” along the path to a zero-waste economy.
The new law might also prove crucial in finally addressing the carbon footprint of the plastics industry.
For instance, the law requires that disposable plastic bottles in Chile must be composed of a percentage of plastic that has been collected and recycled within the country. The Ministry of Environment will enforce and regulate this process through a plastic certification process. However, the exact percentage, or what qualifies as “recycled” material, is unclear.
Plastic manufacture is often overlooked as a significant source of carbon emissions. For example, in the U.S., plastic manufacturing is expected to overtake coal plant emissions by 2030. At the same time, recycling rates have never surpassed 9% in the U.S., and plastics companies have been found to overstate the feasibility of recycling plastics since the 1970s, Mongabay previously reported.
“Only upstream measures such as a cap on plastic production will prevent further degradation of our life-supporting ecosystems,” Melanie Bergmann, a plastic pollution and microplastic expert at the Alfred Wegener Institute in Germany, said in a previous Mongabay article.

The plastic prerogative
An estimated 12 million to 14 million metric tons of plastics enter the ocean every year, according to the IUCN. It’s not known what proportion of this can be attributed to single-use plastics, though these are the “most visible” forms of pollution, IUCN plastics expert Joao Sousa told Mongabay in an email.
Yet, plastics also have their benefits, Sousa said. Their cost-effective, durable, lightweight and waterproof nature is precisely what makes plastics so versatile and lucrative.
This time, the Chilean Plastics Association (Asociación Gremial de Industriales del Plástico de Chile, or Asipla for short) was part of the meetings held with the Chilean senate and other officials for the drafting of Chile’s newest law against single-use plastics.
“Even though we were 100% conscious about the impact of plastics on the environment, we also are convinced of the many undeniable advantages that plastic has given society since its existence,” Magdalena Balcells, general manager of Asipla, told Mongabay.
Without plastics, for example, the world wouldn’t have the face masks (N95 masks are made from synthetic plastic fibers) or medical equipment necessary for managing the COVID-19 pandemic.

“We all want to have fewer residues in the world — it’s not just plastic, but glass, paper, cardboard, and aluminum. But if it’s unfeasible, we are not doing any favors to the environment,” Balcells added when asked about Asipla’s experience being included in Chile’s bill-drafting process this time around.
The various parties “had their differences,” Balcells said. Proposals to ban the production of PET bottles altogether or to deem all forms of packaging as single-use materials were floated, but ultimately ruled unfeasible. But the parties involved eventually met in the middle.
“We are very satisfied with the outcome,” Balcells said. “Though the scope is not huge, it is visible enough for people to change their habits. And that’s a very good thing.”

Transcript

Brian BienkowskiAll right, today’s guest hanging out is Dr. Max Aung, an assistant professor at the University of Southern California Keck School of Medicine and assistant director at the Agents of Change in Environmental Justice program. Aung talks about the mix of insidious pollutant exposures we all face, how these exposures impact the most vulnerable among us, and how policy can catch up to the ever growing list of concerning chemicals. Enjoy.So Max, it is good to see you. But I will full disclosure for the listeners, I see you quite a bit now, you are part of the agents of change program, you are now an assistant director. And you were also part of our first cohort, and you wrote an essay about oil and gas development where you grew up. So I just want to start there, if you could tell me a little bit about what that experience was like, as a researcher being out there with your views and thoughts, what the reception was, to your article and a little bit about the work you’re doing now with us?Max AungYeah, so, you know, the article was such a great opportunity for me to reflect on the sort of environmental issues that are facing communities that have high oil and gas production. But it was also interesting, because having grown up there, you know, I’ve, I’ve had friends that work in the oil and gas fields, that’s like their first job out of high school, it pays really well. You know, it’s it’s basically the source of economic growth for a lot of folks in those communities. So, in my essay touched on that a bit – thinking about, you know, sort of how even though these have environmental impacts these different industries, there’s also this issue of like, how do you deal with folks that rely on this for their everyday lives? So I think, you know, when I wrote the essay, it was largely, you know, well received from I had some folks, you know, reach out to me, and, tell me that, that they found the article to be an important reflection on that balance. I’ve had, we got this article invited to be like in a undergraduate textbook chapter, which was really exciting, you know, that new scholars will be reading this as they think about creative writing and reflecting on environmental issues. And, yeah, so, you know, I think that’s sort of been a great foundation, as I’ve sort of navigated this next stage of my career and thinking about ways to incorporate communities and think about communities inputs, as we tried to shape policy, environmental policy. And so that’s been a huge factor, especially with some of my work at UCSF, which, you know, we can talk a little bit more about later on. In terms of the [Agents of Change] program, so I joined the leadership here in March. And it’s been really exciting because I’ve been working really closely with Dr. Ami Zota, you and Yoshi as well, and just thinking through different ways that we can engage existing scholars in the program, but also ways that we can, you know, galvanize the new cohorts towards different focus groups and thinking about how can we leverage that skill in terms of outreach and in terms of getting our Agents of Change fellows out there to you know, communicate with important stakeholders. So that’s been really exciting so far.Brian BienkowskiGood. And it’s so awesome to be part of the program and already a few years in have people like yourself who are part of it, who have now grown in your career and have new positions, and then come back. I mean for me when I started this, to already see people like you coming back and being a part of it after being in the first cohort, is just, it’s just wild how kind of fast time flies, but it’s been really excellent. And just for people listeners who maybe didn’t read your essay, so it was focused in Kern County, California, right?Max AungYeah, yeah.Brian BienkowskiYou’re right. And I really appreciated the idea of thinking about the economic ramifications. I thought that was one of the aspects of your essays that was crucial when we think about weaning off oil and gas or just trying to get rid of polluting, polluting industries, thinking about the people that rely on these for their livelihoods.Max AungYeah, and it was, you know, it’s so great. Like, during our sessions, like in that first fellowship year, just, you know, getting the feedback from you, workshopping it with the other fellows was such a great experience. Because I felt like, I was consistently challenged to think about every single word I put into that essay, and like the impact, you know, and not being afraid to say, radical, social justice oriented things. And I did feel like that was such a great learning experience, sort of go through that exercise.Brian BienkowskiWell, that’s great to hear. And I hope future folks feel the same way. That’s definitely the spirit of the program. And so you went to University of California, Santa Cruz for your undergrad, and I believe you’re at University of Michigan over here for your masters and your PhD – I love Ann Arbor, is such a fun town. What drew you to public health? And how did you come to start researching environmental exposures?Max AungYeah, so okay, at Santa Cruz, I’d say I gained a really diverse set of research and education experiences. So you know, my undergraduate training was in molecular biology. And so I was just really drawn to some of my more advanced coursework around immunology, and thinking about the different mechanisms that underlie various different health conditions. And that’s was sort of, you know, my bedrock in terms of the coursework. On the other end, I was doing research in a stable isotope laboratory, in the ocean sciences department, which is totally, you know, not, you know, totally different in terms of science, but like, just a totally different direction in terms of how to apply scientific research. And so in that lab, I was working with an exciting team to reconstruct past sea surface temperatures over the course of several thousands of years. So we…the Paleo climatology lab is very focused on trying to understand past climate conditions so that we have data to inform future climate models. So there’s this, you know, this duality between the molecular Health Sciences and more environmental, climate-change focused research. And I think, you know, trying to think through these two different experiences, it was a little bit next, like, after undergrad, you know? I struggled a little bit with trying to find my path forward.And after undergrad, I actually, I took two years, where I wasn’t in school, I was teaching full time for a STEM diversity program that focus on retaining undergraduates from historically marginalized backgrounds in the STEM fields. And so during that time, it gave me a little bit more breathing room to like, think through sort of what are my next steps, and, I got involved with the Society for the Advancement of Chicanos and Native Americans in Science, so I was working with them in the summer. And through that, I started networking with all of these different – because they’re so well connected with all of these universities across the country – and, and through that I sort of got connected with different professors from different schools of public health. And as I was brainstorming through potential graduate training, and really tried to lean in on those background experiences. It became clear to me as I was learning about grad programs that something that would fulfill me is a blend of environmental research, plus Health Sciences, plus policy, right? And so I kind of converge it to like environmental health policy is like sort of where I was thinking. And then so when I was looking at different programs, you know, Michigan really stood out to me. They had a super strong Department of Environmental Health. And when I spoke to different faculty and different current students, it seemed like there was a lot of opportunity if you came in with environmental health to sort of branch out, and also gain skills in policy and some of the more data analysis, epidemiology heavy coursework.So that’s the way, that’s the sort of path that brought me to Michigan. And at Michigan, you know, I don’t think any of this was planned, but I was able to receive this really exciting fellowship from the Robert Wood Johnson Foundation, it was called the Health Policy Research Scholars fellowship. And that really just amplified my health policy training. And it basically allowed me to integrate that type of training into my more science-heavy applications in environmental health. And so, you know, that’s sort of like my entry point into public health and the way I’ve been navigating it in terms of like, career trajectory.Brian BienkowskiWhat’s one place that you miss in Ann Arbor?Max AungOh. I love ramen. I think anybody that knows me really well knows that I’ll always, you know, go find like, the best ramen shop in any city I’m in. So there’s actually like a pretty, you know, delicious ramen place in downtown Ann Arbor called Slurping Turtle. And so that’s one place I miss. Where I was living most recently in Ann Arbor it’s in the middle of the campus and my home, or my former home. So like, you know, on the walk back, I had been known to just like, be like, alright, canceling dinner, cooking dinner, I’m just gonna get ramen.Brian BienkowskiYeah, there’s, there’s a lot, there’s a lot in a town, that’s not huge. There’s a lot of super good food and good music and good places to get a drink. So, before we get on to how you’ve taken that environmental research and what you’re doing with it now, I wanted to ask you, what’s the defining moment that shaped your identity?Max AungOh, yeah, um, you know, I, so I think I can, you know, I could time travel back to a lot of different moments long, longer times ago, but I actually, I think, like in terms of something that’s really defined me, it’s like, for me, one of the experiences, most recently was, I was working at UCSF, and I had the opportunity to, basically, you know, co-lead my first big R1 proposal. And I think what was really exciting about this proposal was, I was focusing on basically trying to better understand mental health disparities among immigrant women, and focus on how environmental exposures are potentially impacting mental health disparities in this population. And I think what was like really pivotal for me as, as a scholar was, this is sort of a moment where, after I’ve developed all of the training, earned the PhD, got to this point in my career, I’m able to now develop research questions and research proposals that literally converge my identity as an immigrant scholar, but also focus on important salient problems that are impacting these communities. You know, I will say that grant hasn’t been funded yet. So we didn’t get it on the first try. But I, I will be persisting on it and trying again, and, reshaping it in different ways. But nonetheless, I still look back at that experience and think that it’s been a huge moment for me to I’m really just feel empowered to use my skills to, you know, and my lived experiences to pursue research that, that not very many folks are doing and I think is really important.Brian BienkowskiYeah. And hopefully bettering science and shaping what environmental science looks like. And then take it one step further, hopefully making lives better, right?and in the communities you’re researching, or are looking into, in some way, having a positive impact. So that’s definitely a defining moment. I think that’s great. And hopefully it gets funded at some point.Max AungYeah, eventually I’m trying, I’m trying, you know, different ways to sort of get it funded. So crossing fingers.Brian BienkowskiSo now you’re really broadly your focus now is on what we’re exposed to that impact our health and human development. So just just kind of a 10,000 foot view, walk me through some of the things that we’re exposed to that kind of keep you up at night? What are you looking at, exposure wise, that we should be concerned about?Max AungYeah, so. So, you know, historically, in terms of what I’ve done research on so far, I’ve focused a lot on endocrine disrupting chemicals. And this includes, for example, a lot of different chemicals found in plastics and different personal care products that you use on a daily basis, like lotions, shampoos. So you know, some chemicals include phalates, phenols, parabens, I’ve done a lot of research on these endocrine disrupting chemicals. Particularly, I’ve focused on how they’re influencing maternal health conditions, and potentially, what implications that has for infant health later in life. And sort of my core research applications in that space is to try to disentangle biological mechanisms, right? So that’s, that’s sort of in the bedrock of my PhD dissertation: identifying different biological pathways that might be affected by these chemicals, and trying to illustrate that in these different studies that that we’ve published, so that so that different scholars can learn about those mechanisms, and build on those when they think about risk assessment, and trying to identify high-risk scenarios with these high exposures and thinking about what pathways might be influenced by those exposures.Brian Bienkowski Can you talk a little bit about… so I think when we historically think about environmental pollution and things that harm us, we think of… let’s use lead for an example, the more lead that I’m exposed to, or that my nephew is exposed to, the more toxic it is. With endocrine disrupting compounds, it doesn’t always work that way, there can be very tiny amounts of exposure that that wreak havoc on the body and maybe at a higher exposure, it’s not the same. So can you talk a little bit about first of all, when we say endocrine disrupting compounds, what what we mean, and also kind of the challenge of identifying how toxic they are, because they don’t always behave like traditional toxics.Max AungYeah, that’s a good point. Yeah, so, just to set the baseline. So when we say endocrine disrupting chemicals, essentially, what that means is that these chemicals, especially, based on in vitro, mechanistic laboratory experiments, these chemicals have been shown to have properties where they can mimic hormone signaling, and they can essentially alter concentrations of different hormone production. And this has, I mean, even though we call them endocrine disrupting chemicals, this has wide implications for various different pathways, because not only can they affect the endocrine system and hormone production, but because the endocrine system is so intimately connected to the immune system, for example, these chemicals can also elicit inflammatory responses, so, they can, you know, cause immune cells to regulate these proteins that are involved with inflammation and this can have downstream effects on cardiovascular function on tissue damage. So, all sorts of different downstream effects. And that’s what makes these chemicals you know, very tricky to understand. Because if they’re affecting various different pathways, there’s all sorts of feedback loops that might be occurring. And disentangling those different feedback loops, and those different mechanisms is really challenging. In terms of the dosage, you know, what you’re saying is about the concentrations, and different levels of concentrations being important, that’s also a huge consideration, right? Because, you know, there’s some evidence that, you know, particular endocrine disrupting chemicals can have nonlinear relationships. So it’s like, even low doses can have effects, and maybe you might not see effects in the middle range, but then you might see effects in the higher range. And, you know, that’s really tricky, especially when you’re trying to investigate these chemicals in a large, prospective cohort, an epidemiology study, where you have a huge distribution of these chemicals, and the distribution might be different based on which study population you’re focusing on. So, yeah, all of those things are incredibly challenging. And, a lot of the research and collaborations I’m working on now, is these, you know, multi center, multi cohort investigations, where we’re integrating data across different birth cohorts. And that’s one of the ways that we can sort of tackle this problem is having a larger sample, a larger, diverse sample that we can have a better understanding of the different distributions of these exposures.Brian BienkowskiSo, as you mentioned, a lot of your work is focused on babies, pregnant people, kind of fetal exposures. Can you talk about the specific vulnerabilities for these groups? And what we know about environmental exposures during this really critical window of development?Max AungYeah, so basically, a huge piece of my research is built on the developmental origins of health and disease hypothesis, which proposes that early life exposures can have, can be affecting key biological processes in utero, that can essentially influence the trajectory of infant development for many, many years. So this could be metabolic health, this could be neurodevelopment. So particularly, I’ve been focused on neurodevelopment, and that’s where my research program is shifting towards right now, in terms of my funded projects. And what we’re seeing so far is that, from preliminary data, that maternal biomarker profiles that we’ve measured in some of our pilot studies are associated with early measures of infant neurodevelopment. So after pregnancy. And those same biomarkers are also associated with environmental chemicals, such as the phalates from the consumer products. And so you know, our running hypothesis is that these chemicals are influencing different biomarker profiles in the mom during pregnancy, and that’s potentially influencing key neurodevelopmental features in the developing fetus, and that’s persisting into infancy. And so that’s one of the major pieces that I’m trying to work on. And so right now, we’re building on that preliminary work, and we’re expanding it into multiple different cohorts measuring these biomarkers. And the idea is that, from the study, we’ll be able to characterize these early mechanisms of neurotoxicity, potential neurotoxicity, but then also, hopefully use these biomarkers as you know, potential predictive tools that we can help to identify potential neurodevelopmental outcomes later in life.Brian BienkowskiSo just so I’m clear that the basic idea is that the mother is exposed to, or the pregnant person is exposed to a compound, and you’re seeing… and by biomarkers, what do you mean, what are you looking at?Max AungYeah, so there’s all sorts of biomarkers that you know that we, that I’ve been researching over the past few years. But most recently, I’ve been focusing on these targeted bioactive lipids, so this includes, you know, parent fatty acid compounds that folks get from, you know, essentially their diet like arachidonic acid, linoleic acid. And these fatty acid compounds are essential, and you know, you need them for key biological processes. And as a component of their essential function and role in physiology, they are metabolized into secondary molecules that can stimulate different things like immune responses, cardiovascular function, they’re also important for, you know, kidney function. So, these secondary molecules are really key signals of biological processes. And so, when you measure them, and then you see that there are altered levels, or different concentrations associated with higher concentrations of phalates, then you start to be concerned, because, you know, that essentially suggest that perhaps, that the chemicals are influencing that metabolism of those bioactive lipids, and if they’re influencing that metabolism, they might be influencing all those downstream processes that I just laid out. And that’s, you know, that’s when we start to find that there might be a problem with that, because those downstream processes could be influencing the developing fetus.Brian BienkowskiSo using a lotion that has too much phalates could make your child have delayed development, maybe some kind of behavioral issues. I mean, are these the kinds of downstream impacts you’re looking up?Max AungWell, we’re trying to disentangle that. It’ still very early stages in terms of those outcomes, but some of my colleagues in that I collaborate in these cohorts have found associations with dilates and altered infant neurodevelopmental parameters. And so we are seeing evidence so far that there are some associations. And so now that we’ve seen those relationships with dilates and neurodevelopment, this next stage that I’m proposing is trying to find these linking pathways, with these bioactive lipids that might be explaining some of these relationships.Brian BienkowskiAnd of course, as humans, we’re all eating perhaps produce that has pesticides, we’re putting on these lotions, we’re eating out of plastic containers, we’re walking outside where there’s heavy traffic, so we’re exposed to mixtures of pollutants all the time. So can you outline, you know, first, why that’s a challenge for researchers like yourself, and how folks like you try to best capture what these mixtures might be doing to us, or disentangling them? If that’s what you’re doing.Max AungYeah. So yeah, so thanks for bringing that up. You know, there’s, there’s hundreds of thousands of chemicals that were exposed to, and like you said, pesticides, and some pesticides have been shown in mechanistic models to be neurotoxic. So when you think about, you know, the cumulative exposures of pesticides, phthalates, toxic metals like lead, and, what is so challenging about understanding any single chemical class is that they’re not acting alone, right? You have these different exposures that are also influencing these biological pathways. And they’re also, through that mechanism, potentially influencing those outcomes like neurodevelopment. And so you know, what I’d say, in that space of disentangling the mechanisms. I think what’s really challenging is, you know, one of the studies I published like a couple of years ago is we looked at like four different chemical classes, you know, dilates, included toxic metals included, and we saw that they’re having these, in some cases, divergent associations with these biological pathways and these biomarkers, and so when you see divergent pathways, it’s really tricky because it’s hard to understand what that implication is in terms of the downstream effects. Like are they acting sort of against each other? like antagonistically? Is this an issue of temporality, where we’ve only measured the exposures once and the biomarkers once so we’re not capturing the bigger picture, right? So there’s a lot of unanswered questions in terms of like these mixture effects. But I think, in that chaos and confusion of all these different divergent relationships, I think there’s something really compelling in terms of this really emphasizes the need to look at chemicals as a whole mixture, because you’re going to miss things if you don’t, right? if you focus on just one chemical class, you’re really going to miss the fact that other chemical classes are having. And it’s, it’s really not conducive for risk assessment, you know, when you think when you’re ignoring those different chemical classes. And so, you know, in terms of taking the risk assessments and thinking of downstream policy implications, I think it’s really critical that we start to evolve from this one chemical at a time policy approach and thinking about all of these chemicals, cumulatively.Brian BienkowskiSo that leads me nicely into my next question, and maybe that’s in part your answer. I was thinking about, I’ve been, personally, I’ve been writing about BPA for more than a decade now. And the bad news keeps coming. And the studies keep finding impacts, whether it’s animal studies, or correlational, human epidemiological studies, and it’s still not regulated, right, nothing happens. And one of the things I realized as a journalist pretty early on that I think is was surprising to me, and I think it’s surprising to other people is that everything on the shelf isn’t tested to the extent that you think it is. So, you know, we you’re talking about phalates and things that are probably in my shower right now. So, where’s the regulation failing? So maybe one one aspect you mentioned, is not looking at things as classes rather trying to look at them individually, but what else? What else could we or should we be doing?Max AungThat’s a, that’s a big question. You know, I think there’s so many different things we could be doing better. But, you know, one of the things for sure is, you know, in addition to looking at the cumulative effects is thinking about better capturing different routes of exposure and integrating that holistically – especially thinking about different historically marginalized communities as well, because there is historic exposure that needs to be accounted for in marginalized communities. So, you know, some communities are exposed to not only the phalates, but high levels of air pollution, toxic lead, there’s PFAS in the drinking water. So thinking about historical exposures as well is really important, because that really contextualizes the current state of the problem that those communities might be facing. Whereas if you just look at the chemical class in isolation, without thinking about those historic exposures, you’re going to underestimate the risk that those communities are experiencing.Brian BienkowskiWhat would you tell someone who’s an expecting mother?Max AungThat’s, you know, I think, what I would tell them is that, you know, well… I think in general, what I would tell folks is that a lot of the solutions, the really big impact solutions are going to come at the regulatory policy level, we can try to limit our exposures as a consumer by, you know, not using this product or that product. You know, avoiding different products, but that’s really so marginal in terms of exposure reduction. I think the onus should really be on regulators and industry to not use these chemicals and to use safer alternatives or if some of these chemicals are not essential, basically, yeah, like they shouldn’t be produced. So in terms of what I tell folks when they asked me about reducing things like, in addition to, you know, avoiding certain products, I would say, it’s really, also going to take a lot of civic engagement to push policymakers to make responsible decisions on reducing these harmful exposures. That’s really where the big-impact, exposure reduction is going to come from. And so, you know, I think that’s where we really have to invest our energy and our effort, as scientists as activists, and sort of pushing policymakers and industries to sort of do better.Brian Bienkowski Was there an “aha!” moment for you or something that you learned when you were researching these exposures that you don’t think most people would know about? Something kind of surprising, interesting, shocking.Max AungYou know, I think like, for me, it’s, it’s been… Well, the first part was just seeing how many chemicals we’re exposed to. It’s pretty alarming. And there’s estimates that there’s like, hundreds of thousands of registered and, you know, thousands of unregistered chemicals too, and that is really problematic, because as a scientist, it’s really, it’s really challenging to investigate the health effects of these chemicals, when there’s like such a large mountain of chemicals. And so I think that was been sort of a huge moment, in terms of the way I think about the problem. And it’s also compelled me to not only investigate them, to the best I can with these epi cohorts –we’re very limited in those cohorts on what we can measure, right, just because of costs– So that’s compelled me to, you know, in addition to focusing on those, also think about how we can drive policy forward. And one of the things I’ve been working on in my role at UCSF, in my past, while at UCSF and I’m still carrying it forward, is thinking about developing a framework to inform policy action when there’s limited research, and to sort of, how can we drive decision making forward? so that we can reduce exposures without having to necessarily conduct these large epi cohorts that will take many, many years to do. So finding that balance has been really tricky. And that’s, you know, something sort of that I’ve been focusing on a lot recently, and it’s really great in terms of bridging my policy bug right into my science hat.Brian BienkowskiI wonder if that might be the answer to my next question. I was thinking about a lot of everybody in the Agents of Change program, there’s a, there’s a real importance placed on using your research to spur positive change in communities. And I think in some instances, I’ve seen this with reporting, when we report on a fence-line community, and there’s a power plant, it’s a very clear link: these people are being harmed by this thing, how can we make that known and spur action? It’s easy, it’s local. Whereas what you’re looking at is so ubiquitous and big. And really, we’re all exposed to these compounds and in some communities more than others, but being such a big, unwieldy problem. I’m wondering how you go about trying to make that change happen?Max AungYeah, so that’s definitely an ongoing workshopping and brainstorming process. In terms of like, how I’ve been approaching it with my collaborators at UCSF, we’re developing thi framework for Environmental Health Policy. And the goal of the framework is to develop a process, a very transparent process for evaluating scientific evidence to inform policymakers to take action on an environmental contaminant. And so in that process, it requires the integration of key decision criteria, right? Like how will you balance the costs and benefits of an intervention? How do you balance environmental injustice and the potential to essentially push back against systemic racism? you know, how can the intervention do that in terms of environmental hazards? And in this process, like, I think the way that we’ve sort of started to approach it is bringing in key stakeholders, from NGOs, from the government, from different community organizations, and really listening, trying to listen on their input. And so that’s one of the most recent things we did in this project: [it] was to bring together a workshop of different key stakeholders. And so now going forward, you know, we’re synthesizing through that information. And as we develop future case studies and applications for our policy framework, I think, will continue to sort of bring in community engagement and really trying to get their input every step of the way, so that we’re impacting a potential intervention with their ideas in mind and very integrated into how we’re approaching the potential intervention or recommendation.Brian Bienkowski I remember talking to Dr. Reginald Seeley, who who spoke to the Agents of Change at some point. And he mentioned when he worked on The Hill for a little while, how incredibly busy policymakers are. This idea of you doing some of the work for them and taking the studies and running them through this project and giving them different outputs of “this would do this, And this would do that. And there’s benefits here cost saving here,” I think is brilliant.Max Aung Yeah, absolutely. It’s a big, it’s a big hill, but I think that, you know, I’m optimistic. And I think we have a stellar team of collaborators. And we’ve brought together a great steering committee to help guide us. It’s really exciting. So I’m hopeful that we can continue that work and really influence policymakers in the future.Brian Bienkowski Excellent. I just have a couple more questions for you, Max. And this has been a really good time it is there anything else that you want to mention that you are optimistic about? Some of these topics are just heavy. What else out there gets you excited or hopeful?Max Aung Yeah, I think, you know, in terms of like, the science, I am pretty, I’m getting optimistic about how some of the funding opportunities that have been announced through the NIH, I’m starting to see more and more emphasis on important research that has implications for environmental justice. And not just NIH but also the EPA. There’s an environmental justice intent in some of these opportunities. So, I’m cautiously optimistic that they can influence positive change and promote social justice. You know, and hopefully, the folks that get these different funding mechanisms can incorporate community input, and really drive environmental justice forward. And I think there’s also a lot of potential in terms of a lot of initiatives that the Biden administration is doing, in terms of trying to integrate social justice into a lot of their regulatory frameworks. And so I think, I’m optimistic about that. I really hope it can be sustained after like the midterm elections, and hopefully in the next four years, but, we’ll see.Brian Bienkowski of living. Yeah, article, political realities. Yeah, unfortunately, sometimes But you know, I what I will say is the fact that there is an awareness, you know, easy for me to say I’m not a member of a community that is dealing with these things. But I think the fact that there is awareness right now is a positive step in itself. And hopefully that continues to bring about change. So Max, I have three rapid fire questions where you can just give me one word, or phrase and then we can, we can move on, get me out of here and the rest of your day. So one of my all time favorite moviesMax Aung Moulin RougeBrian Bienkowski When I have downtime, I am most likelyMax Aung Cycling outdoors.Brian Bienkowski Oh, gosh, me too. I’m taking one as soon as we get done here. And I cannot I cannot start my day withoutMax Aung Coffee.Brian Bienkowski Perfect. We are two for three on matching each other there. And Max. My last question, what is the last book that you read for fun?Max Aung I just started reading this book called “On Earth we’re briefly gorgeous.” And I haven’t finished it yet. So I’ll let you know what when I finished it, but so far, it’s really poetic.Brian Bienkowski And who is the author on that?Max Aung I hope I’m pronouncing their name right. Ocean Vuong.Brian Bienkowski Yeah. “On Earth We’re briefly gorgeous.” I love the title.Max Aung Yeah, it’s a beautiful title. And their background is largely in, you know, in creative writing and poem. So it’s got that sort of that vibe in there quite a bit.Brian Bienkowski Excellent. Well, Max, thank you so much for taking time today. I really mean it that I am so excited that you’re part of the team and I get to see you and talk to you and brainstorm with you on how to grow this program. So thank you so much for today.Max Aung Yeah, thanks so much for inviting me.

How microplastics from cigarettes pollute our oceans

CBS 8’s Chief Meteorologist Karlene Chavis breaks down how to filter out our oceans biggest problem: cigarette butts.

SAN DIEGO — Beach cleanups are common along our coastline, and the most reported pollution problem are cigarette butt filters. They are a costly health hazard for not just us, but the environment. 

Travel from storm drains to beaches

Whether the filters are put out in the sand or make the journey inland from areas like Downtown San Diego through storm drains, they will also find a way onto our beaches. I took a stroll along the sands of Ocean Beach with Mitch Silverstein. He is with the San Diego Chapter of the Surfrider Foundation. It did not take long to find cigarettes butt, and I mean a lot of cigarette butt, pollution. 

“How far did we walk? 100 feet and we got 50 butts. That’s crazy. It’s nuts, it’s nut balls,” said Silverstein. “The beach is not an ashtray.”

I asked Silverstein and Dr. Thomas Novotny, who was also present for this all too familiar show and tell, what do you say to people who believe “well I’m only putting out one cigarette butt, where’s the harm?”

“One, there’s six trillion cigarettes manufactured globally, you put one, the next guy puts one, the next million people put one, and what we find is that a third of all the beach litter picked up from the beaches is cigarette butts,” said Novotny.

Number 1 marine pollution

Novotny is the Professor Emeritus at the San Diego State University School of Public Health. This environmental concern is echoed by many organizations including the National Oceanic and Atmospheric Administration, known as NOAA, citing cigarette butts as the number one marine pollution in the world. 

Novotny refers to cigarettes as a teabag of toxins citing the seven thousand chemicals found in them, including 50 of which are capable of causing cancer. And to top it off, these filters, that have all those toxins locked in, are single use plastics. Don’t let the appearance of a paper lining fool you.

“The filter, which is the most picked up item of the cigarette butts is plastic. It doesn’t bio-grade, it stays in the environment. It gets squashed, broken up into small pieces and is retained as microplastics in the environment as well. Both have a chemical and plastic pollution with cigarette butts,” said Novotny.  

Microplastics

To better illustrate how microplastics get dispersed into our environment, Mitch Silverstein uses a piece of Styrofoam as an example.

“It is the most easy to see example of how one piece of plastic, this from a cooler, instantly turns into thousands and thousands and thousands of pieces. It becomes indistinguishable from the sand,” said Silverstein as he breaks apart the chunk with his hand.

Once broken down, but not gone, the microplastics associated with cigarette filters become imbedded in our environment and even us.

“It’s also a sponge for toxins. So, it soaks up toxins. Fish eat it and we eat that fish, and we get those toxins, and we get that plastic. So, we’re eating it,” said Silverstein.

Taking action 

When it comes to putting out this issue, Novotny advocates for an upstream way of preventing this top pollution. He wants legislation passed that would ban the sale of filter cigarettes, citing the filter itself has no health benefits.

“It is not just the environment, if we can reduce tobacco use in any way, even a small percentage we are going to improve the health of Californians, reduce the cost of healthcare, reduce the cost that is involved in cleaning up beaches and urban environments and just spoiling the natural environment that we have,” said Dr. Novotny. 

Mitch Silverstein echoes this sentiment on the ban with involvement on a local and State level. 

“We can try to blame litterbugs all we want, but at the end of the day, we need to hold the producers responsible and we need to prevent every single cigarette from having a plastic butt, where evidence is overwhelming that it’s hazardous waste and highly likely to end up in our environment,” said Silverstein. 

Unfortunately, on a State level, a bill is introduced during every legislative session that never makes it out of the committee process. Mitch says pushing for this policy change is going to come down to the data, and we can help.

“We have a great tool, Surfrider — any individual can have an account and add to the data that we collect because we need to show policy makers the data. You know, not just come out and say, “hey, you know I feel like the ocean is being polluted”. We know it and we have the numbers to back it up.”

Palau study reveals microplastics are infecting the most pristine corners of the world

Plastic pollution is so insidious that it has entered even the most sacred of places. In 2012, a seal washed ashore in Massachusetts because its stomach was inflamed by all the plastic it had swallowed; seven years later a submarine diving to the bottom of America’s deepest point, the Mariana Trench, discovered a plastic bag; and as recently as March a study revealed that three out of four people have microplastics in their blood.
RELATED: What is microplastic anyway? Inside the insidious pollution that is absolutely everywhere
Since microplastics are so small that they have entered our blood — plastic particles are by definition less than 5 millimeters in length — it stands to reason that they have contaminated the most pristine human locales on the planet. A new study published in the journal PLOS One confirms that this is indeed the case, as scientists from the Palau International Coral Reef Center studied the pristine reef area of the tiny, remote island republic, which lies east of the Philippines and north of New Guinea in the Atlantic Ocean. Mixed in with the beach sand, seawater and natural sediments, the scientists found a troubling number of microplastics (MPs) and nanoplastics (NPs), or plastic particles that are far tinier than 5 millimeters in length.

“Plastic is literally everywhere — it is not just in the streets and oceans; it is in the food that we eat, the water we drink, and the very air that we breathe.”

“This study shows that plastic pollution must be considered in environmental studies even in the most pristine locations,” the authors explain in their abstract. “It also shows that NPs pollution is related to the amount of MPs found at the sites. To understand the effects of this plastic pollution, it is necessary that the next toxicological studies take into account the effects of this fraction that makes up the NPs.” In fact, the authors zeroed in on the threat posed by nanoplastics as one of the chief takeaways from their research.

“They are more dangerous because of their size and concentration,” Christine Ferrier-Pages from the Centre Scientifique de Monaco, and one of the co-authors of the study, told Salon by email. “It is estimated that NPs are 100 times more abundant than MPs and in addition, due to their small size, they can enter the cells and provoke quite a lot of damages.”
Ferrier-Pages added, “Plastics, especially microplastics and even more nanoplastics, enter the marine food web at each level of the food web and accumulate in the higher trophic levels, i.e. fish and other commercial organisms. Nowadays, it has been shown that many commercial fish are contaminated, and by eating these fish, plastics are also transferred to humans. The problem with plastics is that there are hundreds of tons of plastics entering the sea each year, and for the moment, there is no good tool to get rid of these plastics.”
John Hocevar, a marine biologist and director of Greenpeace’s oceans campaign, echoed this chief concern when speaking to Salon by email — namely, that plastic pollution appears to last forever.
“Plastic doesn’t go away, it just breaks down into smaller fragments and disperses,” Hocevar explained. “In many ways, this means that plastic gets more dangerous over time. The throwaway packaging we use today adds to the plastic bottles and bags we used decades ago. Today, plastic particles pervade the atmosphere, raining down on even the most remote mountains and islands. Microplastics are also now saturating our oceans, where they are often eaten by marine life or washed ashore.”
Hocevar praised the new study for reinforcing this point, since “much of the plastic washing up in Palau was produced, used, and discarded thousands of miles away.”
Christopher Chin, Executive Director of The Center for Oceanic Awareness, Research, and Education (COARE), also praised the study, observing that it confirms “not only the ubiquity of plastic pollution, but also its inequity; ocean states [like Palau] and those in the global south face a  disproportionate impact from plastic pollution.”
“The public should not only be more aware about microplastics and nanoplastics, we should all be alarmed,” Chin told Salon. “Plastic is literally everywhere — it is not just in the streets and oceans; it is in the food that we eat, the water we drink, and the very air that we breathe.” He drew attention to a study which found that humans typically eat roughly one credit card’s worth of plastic every week.
Given how humans are chomping down plastic without even realizing it, perhaps it is hardly surprising that the reef organisms of Palau aren’t doing much better.
“On the reef organisms, we have performed some studies on corals, which have been published previously in different journals,” Ferrier-Pages explained. “We have shown for example that nanoplastics induce coral bleaching, the loss of the symbiotic algae by corals. As the symbionts provide corals with most of their food requirements, bleached corals enter into starvation. We have also demonstrated that microplastics can reduce coral calcification — the deposition of their hard skeleton.”

Republican governor of Virginia, Glenn Youngkin, has rolled back the previous administration’s plan to phase-out single use plastics in the state (Photo: Glenn Youngkin, Flickr, Public Domain)
Environmental Health News Editor Peter Dykstra and Host Steve Curwood discuss Virginia Governor Glenn Youngkin’s rollback of a plan to phase out single-use plastics. They also remark on the surprising ecological diversity and cleanup efforts of the heavily polluted Gowanus Canal in Brooklyn, NY, before commemorating 30 years since the US stopped dumping sewage sludge in the ocean.

Transcript

CURWOOD: On the line now from Atlanta, Georgia is Peter Dykstra. Peter is an editor with Environmental Health News, that’s EHN.org and dailyclimate.org, and he keeps track of what’s going on beyond the headlines for us. Hi, there, Peter, how are you doing and what have you got for us today?
DYKSTRA: Hi, Steve. We’ve got a story about the Commonwealth of Virginia. The previous governor who left office at the beginning of the year, Ralph Northam, had set up the beginning of a scheme to phase out single-use plastics at all state agencies and state universities. The new governor, Glenn Youngkin, rolled some of that back in favor of pushing the idea of plastics recycling, an idea that we’ve spent many, many years learning does not get the job done.
CURWOOD: So a step forward and, I guess, a step or two backwards, huh?
DYKSTRA: And there was one particularly big program to reduce plastics use and instill other environmental measures at George Mason University, which is a really big commuter school in Northern Virginia outside of Washington, DC. So ambitious was this program, that the new Governor, Glenn Youngkin, recognized George Mason with a Governor’s Environmental Excellence Award in March, and the following month, in April, he issued an executive order essentially cutting the legs out of the single use plastics reduction plan.
CURWOOD: All right, Peter, hey, what else do you have for us for today?
DYKSTRA: I’ve got kind of a stinky story from one of the worst sites in New York City, as far as pollution goes, a Superfund site, the Gowanus Canal in Brooklyn, the site of heavy industry and rampant dumping for a hundred and fifty years, sewage, all sorts of heavy metals like lead, and there’s stuff at the bottom of the canal that’s lovingly referred to as black mayonnaise.

CURWOOD: What a place, huh?
DYKSTRA: Yeah, but there’s a wildlife inventory that’s going on in the canal where they’re finding everything: birds, sea birds, insects, plants, shellfish, finned fish. But one of the issues and conflicts here is that the citizen based effort to clean up the canal is running into the sometimes rigid programs that EPA sets up for cleanup, and some of the Superfund cleanup efforts are getting in the way of the citizen cleanup efforts.
CURWOOD: But, A, it’s helping wildlife and, B, it’s getting remediated, so…
DYKSTRA: Maybe a happy ending someday. It’s just kind of a gross place, but even in this gross place, there’s a concerted effort to clean it up.
CURWOOD: Well, let’s take a look back in history now, Peter, what do you see?
DYKSTRA: Yeah, if you’re ready for a little bit more smelly news out of the same place, good old New York City. On June 30, 1992, 30 years ago, New York City formally ended its practice, more than 100 years old, of dumping sewage sludge into the Atlantic. There was an uproar in the late 80s in New York and New Jersey about medical waste washing up on beaches, trash, sewage, and all sorts of yucky things. But by that date, June 30, 1992. They became the last American municipality to stop barging its sewage sludge out to the nearby ocean and dumping it.

CURWOOD: Well, better late than never. Peter is an editor with Environmental Health News, that’s EHN.org and dailyclimate.org. We’ll talk to you again real soon, Peter, thanks a lot.
DYKSTRA: Thank you, Steve. We’ll talk to you soon.
CURWOOD: And there’s more on these stories on the Living on Earth webpage that’s LOE.org.

To help curb the plastic pollution crisis, the US Department of Interior will phase out single-use plastic products sold and distributed in national parks and other federal public lands it oversees. Christy Leavitt, Plastics Campaign Director at Oceana, joins Host Bobby Bascomb to talk about how the phase out could work and why it matters.

Transcript

CURWOOD: From PRX and the Jennifer and Ted Stanley studios at the University of Massachusetts Boston, this is Living on Earth. I’m Steve Curwood,
BASCOMB: And I’m Bobby Bascomb. Roughly 40% of all plastic produced worldwide each year is thrown away after just one use.And while things like plastic forks, straws and bags may be used for only a moment, they can stick around for up to a thousand years before they decompose.Less than 6% of plastics in the US is recycled, meaning most plastic waste is incinerated, landfilled, or winds up in our oceans.Seeking to curb such waste, Canada has announced a phaseout of the manufacture and import of common single-use plastic starting at the end of 2022 and culminating by the end of 2025.Plastic is made from oil and gas, a major resource for Canada which is one of the world’s largest producers of oil.Still, Prime Minister Trudeau says phasing out single-use plastic is a worthy aim, as the ban would eliminate close to 3 billion pounds of plastic waste over the next decade.
TRUDEAU: Plastic pollution is a global challenge. You’ve all heard the stories, and seen the photos. And to be honest, as a dad it’s tough trying to explain this to my kids. How do you explain dead whales washing up on beaches around the world, their stomachs jam-packed with plastic bags? Or albatross chicks photographed off the coast of Hawaii, their bodies filled to the brim with plastic they’ve mistaken for food? How do I tell them that against all odds, you’ll find plastic at the very deepest point of the Pacific Ocean, 36,000 feet down?
BASCOMB: The U.S. Interior Department has announced a goal to phase out single-use plastics sold and distributed in national parks and other public lands it oversees, but so far the Forest Service under the Agriculture Department has yet to follow suit.The parks system alone had nearly 300 million visits last year and had to deal with some 70 million pounds of plastic waste.
For more, I’m joined now by Christy Leavitt, Plastics Campaign Director at Oceana. And by the way, we should disclose that Oceana is a supporter of Living on Earth through Sailors for the Sea. Welcome to Living on Earth, Christy!
LEAVITT: Thank you. It’s a pleasure to be here.
BASCOMB: So what exactly does this announcement entail? And how significant is it?
LEAVITT: This is a big announcement from the Department of Interior and the Biden administration. So on June 8th, on World Oceans Day, Interior Secretary Deb Haaland committed to phasing out single use plastic products in our national parks and other public lands overseen by the Department of Interior. So what she did was she issued a secretarial order that calls for the department to reduce the procurement, sale and distribution of single use plastic products and packaging on all Interior Department-managed lands and buildings by 2032.
BASCOMB: Now, the goal here is to phase out plastic by 2032, as you just mentioned, but that’s a full decade away. Why does it have to take so long? And what needs to happen between now and then?
LEAVITT: Yeah, well, we are hopeful that they will move quickly to phase out some of the worst, the most problematic, single-use plastics as quickly as possible. Our understanding is that it’s going to take them up to 10 years to deal with some of the specific concession contracts that they have. But we definitely know they’re interested in moving quickly, and we will be following up to make sure that they do move as quickly as possible.
BASCOMB: Well, what kind of impact does plastic waste currently have in our public lands and waters?
LEAVITT: Just to give you the scope of the problem, as we look at our oceans is that every year, 33 billion pounds of plastic enter the ocean. And to put that in perspective, that’s roughly equivalent to dumping two garbage trucks full of plastic into the ocean every minute. And it’s not just harming our oceans, but it’s also our climate and our health and our communities and our public lands. Basically, no place on earth is untouched by plastic. And we’re finding it in our national parks and other public lands. And it has a couple of impacts there. One impact is that nobody wants to look and see single use plastic water bottles or plastic straws or other plastic as they’re exploring the beautiful places like Yosemite or the Grand Canyon. And then it’s also harmful for the ecosystems there. So not only are there the big pieces of plastic, so the plastic bag, or the plastic water bottle, but it also, plastic breaks up into smaller and smaller pieces called microplastic, that then can get into the soil, can get into the air. That’s what we’re finding in rain; we’re even finding it in human blood and in our lungs, too. So we’re finding it everywhere, including in our national parks.

BASCOMB: And to what degree is that potentially a threat to wildlife? You know, the very reason that we’re going to these national parks?
LEAVITT: It is a big problem for wildlife. So not only can wildlife get entangled, or ingest plastic, but the same thing is happening with microplastics, where they might be eating it, they might be, you know, breathing it in, those sorts of things, too. So it’s a problem for wildlife. And when we talk about our national parks, there’s more than 400 different national park units around the country. Some of them are the really big parks, like Grand Teton National Park, and some of them are smaller areas. But 88 of the National Parks are ocean and coastal parks. So they’ve got a direct impact on what’s happening in our oceans as well as our coastal Great Lakes too. So the plastic, if plastic is going out there, it’s gonna end up in our oceans. And Oceana did a survey a few years ago, we pulled together a report that looked specifically at what was happening with animals in US waters. And we found nearly 1800 animals — these were marine mammals, so dolphins, whales, as well as sea turtles — had been harmed by either ingesting or becoming entangled in plastic in US waters since 2009.
BASCOMB: And of course, those are just the ones that we know about and documented, you can be sure the number’s much, much higher.
LEAVITT: That is definitely true. Those are only the ones that people were able to see and observe. But there’s a lot more animals that are being impacted by plastic.

BASCOMB: Now, of course, plastic is made from fossil fuels, and the production of plastic and the plastic itself is a major source of greenhouse gas emissions that warm the planet. And as we know, climate change is one of the biggest threats to our national parks. To what extent, do you think that was maybe a factor in Interior Secretary Deb Haaland’s decision here to phase out plastics on our public lands?
LEAVITT: Yeah, our national parks are definitely faced with extraordinary adaptation challenges. So it’s a critical problem. And it’s definitely something that the Department of Interior and the Biden administration overall are looking at solutions to the climate crisis. As you mentioned, plastics have a big impact on climate. Almost all plastic is created from fossil fuels. So throughout its entire existence, plastic is creating climate changing greenhouse gases, so it’s extracted from, whether it’s from oil and gas, that extraction creates greenhouse gases; then the production of plastic creates more; they’re transported; they then break down in landfills or they’re incinerated or burned. So throughout its whole life, that plastic is creating more and more greenhouse gases. And I don’t think most people think of that plastic bottle or that plastic bag as coming from fossil fuels, but it is. And in fact, if plastic was a country, it would be the fifth largest emitter of greenhouse gases in the world.
BASCOMB: So how will phasing out single use plastic and the national parks and public lands actually work? What might a visitor see that might be different?

According to Christy Leavitt, every year around 33 billion pounds of plastic enter the oceans worldwide. That’s about two garbage trucks full of plastic every minute. (Photo: Courtesy of Oceana)

LEAVITT: I think some of the things that visitors will see at national parks will be more refillable water stations. So rather than buying a plastic water bottle, there’ll be stations at all of our national parks and other Department of Interior sites where you can go and refill your reusable water bottle. There’ll also be inexpensive water bottles for sale, so if you didn’t bring a water bottle, you’ll be able to purchase one right there. And you could use it over again and again. There’s already some of that happening at national parks and this will expand it even more. There are a lot of national parks, you can buy food, whether lunch or for dinner. Some of those are cafeteria style. Some of those are restaurant style. And they can move to reusable plates and dishes and cups and utensils. So they’ll need to create systems to be able to wash all those dishes. But it will be able to make sure that we’re not using single use plastic products in those places.
BASCOMB: Now, from what I understand many of the gift shops and food vendors in the national parks are actually concessionaires who contract with the National Park Service. So how might this affect them?
LEAVITT: Yes, that is definitely the case where a lot of the restaurants or gift shops are being run by concessionaires. And so they will need to make these changes, they’ll need to get rid of unnecessary single use plastic products, whether it’s in Yosemite or a National Seashore or another wildlife refuge.
BASCOMB: Christy, what kind of public support or, for that matter, pushback have you seen for this plan to phase out single use plastic in the parks?

Christy Leavitt is Oceana’s Plastics Campaign Director (Photo: Courtesy of Oceana)

LEAVITT: We know that people love their national parks, as we’ve been talking about a bit here. And we did a survey earlier this year. And we found that 82% of American voters would support a decision by the National Park Service to stop selling and distributing single use plastics at our national parks. So that’s a very high level of support, it’s bipartisan support. So definite interest in protecting our national parks from single use plastic.
BASCOMB: Christy Leavitt directs the plastics campaign at Oceana. Christy, thank you so much for your time today.

What's the best alternative to a single-use plastic bag? It depends

Ottawa recently announced it will phase out some single-use plastics by 2025, but finding sustainable alternatives is trickier than you might think.The ban, which targets six categories of plastics, is part of an effort by the Liberal government to achieve zero plastic waste by 2030. A study commissioned by Environment and Climate Change Canada showed that, in 2016, Canadians threw away three million tonnes of plastic waste, only nine per cent of which was ultimately recycled. The rest ended up in landfills, waste-to-energy facilities or the environment, where it can harm wildlife while taking hundreds of years to break down.One of the single-use items on the banned list is the plastic checkout bag that many Canadians use for groceries and other kinds of shopping. Up to 15 billion plastic checkout bags are used every year in the country, according to government data.They’re also one of the major sources of plastic litter found on shorelines. In 2021, almost 17,000 plastic bags were collected during community cleanups.Even before the federal government’s move, some jurisdictions including P.E.I., Nova Scotia and a number of B.C. communities had already banned single-use plastic bags. Some major retailers such as Sobeys and Walmart have also stopped offering them.The majority of Canadians are shifting away from single-use plastic bags, too. In a 2019 survey, 96 per cent of respondents said they used their own bags or containers when grocery shopping, though only 47 per cent of those said they always did so.Examining the full life cycle The challenge for eco-conscious shoppers is that alternatives to single-use plastic bags also leave an environmental footprint.A 2020 study by the UN Environment Program analyzed the findings of seven life cycle assessments (LCAs) on shopping bags published since 2010. An LCA assesses the environmental impacts of a product or services from, essentially, cradle to grave. This includes: Raw material extraction.Production.Logistics and distribution.Use.End-of-life.The study found the environmental ranking of bags varies depending on which criteria you consider. For example, one type of bag may score well in cutting down on litter but be a poor option when it comes to water and land use to make it.The number of times a reusable bag is used is also crucial, the study found. On the lower end, a paper bag needs to be used four to eight times to have less impact on the climate than a single-use plastic bag. Meanwhile, a cotton bag needs to be used 50 to 150 times to be environmentally superior, according to the study.Given the impacts from all life cycle stages, one of the best options for shoppers would to skip the bag altogether whenever possible, said Tony Walker, an associate professor of environmental studies at Dalhousie University in Halifax.”Reducing consumption of anything and everything is key because everything requires resources and energy to produce,” said Walker, who advised the federal government on its Zero Plastic Waste Agenda and Oceans Plastics Charter.If you do need a plastic bag alternative, here’s a closer look at the pros and cons of some common options.Cotton bagThe cotton bag has greater environmental impacts than other types of bags during production due to the high amount of energy required to grow, irrigate and fertilize the cotton.However, its durability lends itself to hundreds, even thousands, of uses, which makes it an environmentally friendly alternative, says Walker.As well, cotton bags are made from a renewable resource and are degradable at end of life, though the 2020 UN study notes it matters how it is disposed. Waste incineration for cotton bags is climate neutral and therefore a better option than landfilling, where the study says degradation of the cotton releases methane, a greenhouse gas that contributes to global warming.Paper bagPaper bags have a few things going for them: they can decompose easily, they can be put in compost bins depending on your jurisdiction and they can be recycled as paper, says Walker.However, like cotton, they demand quite a bit of energy to produce. They also require forestry products as raw materials and take more fuel to transport than other, lighter materials.Tony Walker, an associate professor of environmental studies at Dalhousie University in Halifax, advised the federal government on its Zero Plastic Waste Agenda and Oceans Plastics Charter.

California’s sweeping new plastics law could be a game changer

The United States creates more plastic trash than any other country and ranks third among coastal nations for contributing litter, illegally dumped trash, and other mismanaged waste to its beaches. Yet, even with such an abundance of disposable plastic—scientists measured 46 million tons in 2016—the U.S. manages to recycle just under 9 percent every year.So, when California’s sweeping legislation on plastic waste was signed by Governor Gavin Newsom last week, the moment was heralded as a transformative shift that may redefine how the nation at large deals with the growing amount of plastic waste.“The magnitude of this legislation really can’t be overstated,” says Anja Brandon, a plastics policy analyst at the Ocean Conservancy, which participated in the lengthy negotiations to craft the bill. “This is the first legislation anywhere in the world that requires a simple reduction in the amount of plastic.”The new law aims to accomplish several big things at once. Most significantly, it requires a 25 percent reduction of plastics in single-use products in California by 2032—a first in regulatory efforts in the U.S. to restrain the growth in plastic manufacturing, which globally is forecast to triple by mid-century to 32 million tons a year. The reduction can be achieved by shrinking the size of packaging and shifting to refillable containers or packaging made from other materials, such as recyclable paper or aluminum. By the Ocean Conservancy’s calculations, those packaging reductions would eliminate nearly 23 million tons of single-use plastics over the next decade. Californians throw away about 4.5 million tons of plastics yearly, according to CalRecycle, the state’s waste management agency.The new law also requires 30 percent of plastic to be recycled by 2028, increasing to 65 percent by 2032—a giant leap. It further requires the industry to create a $5 billion fund over the next decade to help low-income communities impacted by the effects of plastic pollution.Finally, it transfers the cost of recycling to the industry from municipalities and their taxpayers. The practice, known as extended producer responsibility, (EPR) has been in use in the European Union (EU) since the 1990s, and is credited with boosting higher recycling rates in western Europe, which hover around 40 percent.Canada began such an EPR program last year. Other countries, including India, are in the process of writing EPR regulations. In the U.S., EPR has been introduced in Congress, but so far has failed to gain approval. California’s shift to EPR follows Oregon, Maine, and Colorado, which have passed slightly different versions.“It’s been a long time for the dam to break in the U.S.,” says Ted Siegler, a waste expert and partner at DSM Environmental Services in Vermont. He has worked with nations across the globe to develop waste management systems, and has long supported requiring industry to finance the cost of processing the trash their products become. “It will take several years before we will see if any of these EPR laws here are going to work.”California’s long reachThe new law is expected to prompt change in the plastics industry far beyond California’s borders. As the most populous state and the world’s fifth largest economy, California influences markets in ways that other states can’t. Auto manufacturers, for example, agreed to follow California’s fuel emissions standards, which are stricter than federal standards. In plastics, experts predict that product packaging lines, for example, will be adapted to California’s standards no matter where the products are sold.“A national or global company in all likelihood will make those changes globally or nationally, and not just for the state of California—or Maine,” Siegler says. But he also sounded a cautionary note against counting on the new law to live up to its effusive praise as landmark: “My experience with waste reduction measures is they have always failed to meet reduction targets written into the legislation. It would be great if they were able to (in this case). Proof will be in the implementation.”Stricter regulations elsewhereThe EU remains the world leader in regulating plastic products, packaging, and waste. It has banned 10 types of single-use plastic products, including food and beverage containers made of expanded polystyrene or foam, straws and beverage stirrers, and certain biodegradable plastics. The EU also is in the process of revising regulations in order to reduce all packaging. And, to support the use of recycled plastic, it is considering setting mandatory targets for recycled content required in packaging, vehicles, and construction products.Other nations also have taken a national approach. India’s national ban on single-use plastics, announced with fanfare last fall, took effect July 1. More than three dozen countries, most of them in Africa, have banned plastic shopping bags, the world’s most-used consumer product.In the U.S., efforts to curb plastic waste have been scattershot. Eight states have banned plastic shopping bags. Five states have banned expanded food containers made of expanded polystyrene, or foam. The plastics industry has succeeded in persuading lawmakers in more than a dozen states to pass laws preventing such product bans.Federal legislation, which includes a provision calling for a fee on production of virgin plastic used to make single-use plastics, is tied up in Congress. The provision is aimed at leveling the playing field for plastic production: In the U.S., making plastic from virgin plastic is far cheaper than making it from recycled plastic, and those economics contribute to the growing accumulation of plastic trash around the world. Meanwhile, the Biden administration announced last month a plan to phase out single-use plastics in national parks and other public lands by 2032.California already leads the nation in regulating plastics, having banned bags statewide and expanded polystyrene in 128 cities. Last year it outlawed the use of the common circular recycling symbol, found on the bottom of packaging, in cases where the packaging is not actually recyclable.Still, efforts to pass more comprehensive legislation eluded lawmakers until this year. Success this time came largely because the plastics industry joined other proponents to craft a compromise that kept a more stringent plastics initiative, known as the “anti-plastics” bill, off the November ballot.There’s no pleasing everyone Even so, not everyone was happy with the outcome. The American Chemistry Council, an industry trade group that lent support in an effort to derail the ballot measure, nevertheless gave the new law praise, however faint. In a statement, Joshua Baca, the group’s vice president of plastics, said the law is “not the optimal legislation to drive California towards a circular economy,” but pledged to work with California lawmakers to refine several provisions.Judith Enck, a former EPA regional administrator and founder of the activist group, Beyond Plastics, faulted lawmakers for failing to ban expanded polystyrene, and for not closing loopholes that she says may allow plastics producers to avoid meeting their targets. “When the dust settles, there will be some remorse,” she says. “Better than nothing is not a good strategy.”Enck also criticized the EPR program for allowing the industry to organize the EPR procedures and collect fees, though the final authority to oversee the program lies with CalRecycle, the state agency. “Environmental policy makers would not put the fossil fuel industry in charge of reducing greenhouse gases, so why are we putting the packaging industry in charge of reducing packaging?” she asks.Recology, the San Francisco-based recycling company that provided seed money to get the citizen’s initiative on the ballot, praised the new law for its EPR provisions and efforts to reduce plastic packaging, but said in a statement even more legislation and additional funding will be required.“As a recycling company, Recology is doing everything we can, but manufacturers and their packaging companies are producing too many plastics in total and too many different kinds of plastics,” the company said.Recology, which provides recycling and composting service to nearly 150 communities in the three West Coast states, does advise consumers to do their part: “Each time we avoid plastic when shopping, we send direct messages to brands and their packaging companies. If we don’t buy it, they won’t make it.”In the end, what sets the new California plastics law apart is the requirement that reduces plastic production, says George Leonard, the Ocean Conservancy’s chief scientist.“It goes to the heart of the question—the growth of plastic production as a driver in environmental change. Is it everything? No. But it’s going to bend the curve in a more practical way than anything that came before.”

California requires plastics makers to foot the bill for recycling

The landmark legislation also restricts single-use plastics. Because California’s economy is so big, experts say, the law could have far-reaching effects.In one of the most ambitious statewide attempts to reduce dependence on plastics, California instituted a new requirement that makers of packaging pay for recycling and reduce or eliminate single-use plastic packaging.The law, signed by California’s governor on Thursday, is the fourth of its kind to be passed by a state, though experts say it is the most significant because it goes further in requiring producers to both make less plastic and to ensure that all single-use products are recyclable or compostable. Last summer, Maine and Oregon passed the country’s first such requirements, known as producer-responsibility laws.A key tenet of the laws: The costs of recycling infrastructure, recycling plants and collection and sorting facilities, will be shifted to packaging manufacturers and away from taxpayers, who currently foot the bill.The California law requires that all forms of single-use packaging, including paper and metals, be recyclable or compostable by 2032. However, this is most significant when it comes to plastic products, which are more technologically challenging to recycle. In addition, it is tougher for people to figure out which plastics are recyclable and which aren’t.Unlike in other states, California will require a 25 percent reduction across all plastic packaging sold in the state, covering a wide range of items, whether shampoo bottles, plastics utensils, bubble wrap or takeaway cups.“We know that to solve our plastic pollution crisis, we need to make less plastic and reuse more of the plastic we do have,” said Anja Brandon, a policy analyst at the Ocean Conservancy, an environmental nonprofit group, and a contributor to the text of the bill. “This is the first bill in the country to tackle both issues.”Recycling is important for environmental reasons as well as in the fight against climate change. There are concerns that the growing global market for plastics, which are made from fossil fuels, could support demand for oil, contributing to the release of greenhouse gas emissions precisely at a time when the world needs to wean itself from fossil fuels to avoid the worst consequences of global warming. By 2050, the plastics industry is expected to consume 20 percent of all oil produced.According to one estimate by her team at the Ocean Conservancy, Ms. Brandon said that the new California law would eliminate 23 million tons of plastic in the next 10 years.Under the state’s law, manufacturers would pay for recycling programs and will be charged fees based on the weight of packaging, the ease of recycling and whether products contain toxic substances, such as PFAS, a type of virtually indestructible chemicals that have been linked to increased risk of some cancers.It follows other attempts in California to improve recycling. Last September, California became the first state to bar companies from using the “chasing arrows” symbol — the common symbol, three arrows forming a circle, often thought to mean that something is recyclable, although that’s not necessarily the case — unless they could prove that the material is in fact recyclable in most California communities.In addition, the law requires plastics manufacturers to pay $5 billion into a fund over the next 10 years that would mitigate the effects of plastic pollution on the environment and human health, primarily in low-income communities.“For far too long, plastic waste has been a growing burden for humans, animals, and the water, soil, and air we need to exist,” Ben Allen, a Democratic state senator and an author of the bill, said in a statement.Understand the Latest News on Climate ChangeCard 1 of 5Logging.

Environmental Health News Editor Peter Dykstra joins Host Steve Curwood to discuss the statistic that less than 50% of our world’s annual grain production is eaten by humans. They then review the innovative microplastic-removing “fishbots” coming out of a research group at Sichuan University and finish up with an anniversary for the Hoover Dam, a massive source of water and hydropower approved for development 93 years ago.

Transcript

CURWOOD: Well, it’s that time in the broadcast when we turn to Peter Dykstra. For a look Beyond the Headlines, Peter is an editor with Environmental Health News. That’s ehn.org and dailyclimate.org. He’s on the line now from Atlanta, Georgia. Hey, Peter, it’s been pretty hot here. What about down south with you?
DYKSTRA: Last week, we hit 100º a couple of times; this week, it’s a little bit lower than that. But it’s still summertime hot in Georgia.
CURWOOD: Ouch.
DYKSTRA: Well, Steve, let me tell you a couple of things that I found interesting this week. According to the World Food Program, most of the world’s grain is not eaten by humans. We produce just under 3 billion metric tons of grain a year. And more than half of that goes to feed animals or is used as biofuels like ethanol.
CURWOOD: So even in this time of grain shortage, because we’ve got this war going on with Russia’s invasion of Ukraine, and of course, the recurrent hunger problems, we’re not eating half of what we produce, and it’s going to animals?
DYKSTRA: Yeah, we’re talking about all of the common staple grains: corn, wheat, millet, rye, oats. And the world is desperate to feed itself. Ukraine and Russia have more than complicated the situation. But all of that grain that goes to feed animals, in turn, those animals are used to feed us, which creates health problems, climate problems, and more.

According to the World Food Program, humans eat less than 50% of the grain we produce. The majority of grain goes to animal feed and biofuel. (Photo: Kees Streefkerk on Unsplash)
CURWOOD: Peter, since most of the grain isn’t eaten directly by humans, but goes to livestock, if we cut down on our eating of meat as a species, we will not only help the climate – because there’s a lot of climate related gas emissions associated with all that meat – we also help lessen the shortage for other people on the planet who need to eat.
DYKSTRA: That’s right. And if I can say this in the politest way possible, we could use a little bit less meat eating here, where of course other parts of the world don’t get enough food and don’t get enough nutrition.
CURWOOD: So, there’s plenty of grain to go around for people to eat directly as long as we make the right choices. Heya, what else do you have for us today?
DYKSTRA: The word for today is: fishbots. There was a study published last week in the journal Nano Letters. Researchers in China at Sichuan University created a fishbot made out of composite material that can draw microplastics to itself as it swims. The Sichuan University team thinks that the new bot could be used to transport microplastics to another location where they can be collected and properly disposed of.
CURWOOD: Hey, Peter, just give me a little tech lesson. How exactly does this fish bot attract microplastics to it?
DYKSTRA: These fishbots react to a near-infrared light laser. Blinking the laser on and off causes the fishbot tail to flap back and forth acting like a fish. And as it moves along, plastic material sticks to the body of the fishbot.
CURWOOD: This would be an amazing solution to a huge problem. I mean, we’re literally choking the oceans with microplastics. But it sounds like this isn’t exactly an inexpensive device.
DYKSTRA: Not necessarily inexpensive, not necessarily efficient, and certainly not necessarily something that’s going to rid the world of the microplastics problem. But it’s an innovation. And if we have 1000 innovations, we might be able to put a dent in the huge problem of plastic pollution.

On June 25th, 1929, President Herbert Hoover authorized construction of the Hoover Dam (originally Boulder Dam). Today, overuse and drought threaten the American Southwest’s water supply. (Photo: Ryan Thorpe on Unsplash)

CURWOOD: Okay, well, I like that, a sign of hope to deal with the plastic problem. Hey, what do you have from the annals of history for us today?
DYKSTRA: On June 25th, 1929, President Herbert Hoover authorized the construction of a huge dam at the Boulder Canyon near the very small town of Las Vegas, Nevada. The Boulder Dam was eventually renamed the Hoover Dam, and it supplies water and electricity to farms and homes in Nevada, Southern California, and Arizona.
CURWOOD: There doesn’t seem to be a whole lot of water in the Colorado River system now to keep operating the Hoover Dam the way it once operated.
DYKSTRA: The Colorado River and the Southwestern US is in crisis over water. LA, San Diego, Orange County, Las Vegas, Phoenix. And even before you get to watering the populations in the cities or providing hydropower for them, about 70% of what comes down to the Hoover Dam is used for agriculture. So, the Hoover Dam is going to have to work overtime. And they’re going to have to find more new ways to conserve water and to find water to keep the American Southwest powered and watered.
CURWOOD: I think you’re right, Peter. I mean, we’re facing a real crunch there, thanks to the climate and thanks to the development that we’ve brought to the desert southwest. Thanks, Peter for all these stories. Peter is an editor with Environmental Health News, that’s ehn.org and dailyclimate.org, we’ll talk to you again real soon.
DYKSTRA: Okay Steve, thanks a lot, talk to you soon.
CURWOOD: And there’s more on these stories on the Living on Earth webpage, that’s loe.org.
