The state has adopted a strategy to monitor and reduce the ubiquitous form of pollution.A volunteer with the Pacific Beach Coalition picking up trash near Pacifica Esplanade Beach last year.Justin Sullivan/Getty ImagesThey are in your gut. They are in the ocean. They are even floating through the air in the most remote regions of the West. Microplastics — fragments of broken-down plastic no larger than a fraction of an inch — have become a colossal global problem.California wants to fix that.Last month, the state became the first in the nation to adopt a strategy addressing the scourge of tiny detritus. “We need to eliminate our addiction to single-use plastics,” said Mark Gold, the executive director of the Ocean Protection Council, the governmental body that approved the plan.The strategy is not regulatory, but the council has committed to spending $3 million this year, with reduction targets laid out between now and 2030. Gold added, “You find microplastics everywhere you look.”By some estimates, humans have manufactured about 8.3 billion metric tons of plastic, only nine percent of which has ever been recycled. About 11 million metric tons of this plastic end up in the ocean every year, and without intervention, this number is expected to triple by 2040, according to the council. When these plastics break down, they can be eaten by marine animals, stunting their growth and causing reproductive problems. They have also been found in human organs, including placentas, as well as in soils and plants.California’s strategy is part of a global effort to address this problem. Last week, representatives from 175 nations agreed to begin work on a legally binding treaty that would commit them to recycling and cleanup measures, as well as curbs on plastic production. The treaty, supporters say, would be the most important environmental accord since the 2015 Paris Agreement on climate change.At the local level, California’s strategy primarily aims to do two things: First, prevent plastics from entering the environment. Second, monitor those that are already out there.The first step, Gold said, is reducing or ultimately eliminating the worst culprits, including single-use plastics, synthetic fabrics, cigarette filters and car tires. Research from 2019 showed that nearly half of the microplastics polluting California’s coastal waters were rubber fragments probably shed from vehicle tires, making them the largest single contributor to the problem.The strategy also sets goals to improve storm water systems to catch the pollutants before they reach the ocean. “The thing about microplastics is if they get into the ocean environment, they are there to stay,” Gold said.The plan also commits to monitoring levels of microplastics in California’s waters, just as the state monitors the level of harmful particulate matter in the air, which can often increase during events like wildfires. Such a program would be among the first to consistently monitor these pollutants in the environment.It also sets goals to research where the majority of the microplastics are coming from, and how much risk each kind poses to the health of humans and aquatic life. Though scientists agree that plastic pollution is a blight, little is known about exactly how it affects us.“The evidence of harm is not the same as the evidence of presence,” said Britta Denise Hardesty, a principal scientist with the Commonwealth Scientific and Industrial Research Organization, an Australian science agency, and an expert on microplastics, who is not involved in the plan. She added, “It’s awesome that California is doing this.”A floating boom designed to corral plastic debris littering the Pacific Ocean deployed from San Francisco Bay in 2018.Lorin Eleni Gill/Associated PressA sensible state strategy, she added, was far more likely to succeed than some previous efforts, including a giant boom that set sail into the Pacific Ocean in September 2018 with plans to remove 150,000 pounds of plastic from the ocean in a year. “You couldn’t design something to be more costly and less likely to succeed,” Hardesty told me.The vessel returned several months later, in pieces.The hope is that California — the state with the largest economy and among the best environmental protections in the nation — can forge ahead in reducing the harm of microplastics, even if it can’t solve the problem on its own, Gold, the Ocean Protection Council executive, told me.“We’re California, we lead by example; it’s in our DNA,” he said, adding: “We don’t want to wake up in five years and find out this is absolutely devastating to our marine ecology, and we didn’t do anything.”For more:Last week, representatives from 175 nations agreed to begin writing a global treaty that would restrict the explosive growth of plastic pollution.Sending a giant boom into the ocean to clean up the Great Pacific Garbage Patch was probably a bad idea, Vox reports.A study in 2020 showed you’re probably inhaling microplastics right now.State Senator Scott Wiener, a Democrat, is one of the lawmakers backing the repeal of a law that lets voters veto public housing projects.Rich Pedroncelli/Associated PressThe rest of the newsHousing law: California lawmakers are trying again to get rid of the nation’s only law that lets voters veto public housing projects, The Associated Press reports.Trucker protest: A convoy that departed from California last month encircled the nation’s capital on Sunday in protest of Covid mandates.SOUTHERN CALIFORNIAJury rules in favor of officers: Two Huntington Beach police officers did not use excessive force when they shot and killed a man in 2017, a jury ruled on Friday.

On 2 March, world leaders and environment ministers agreed to start negotiations on the world’s first legally binding international treaty to eliminate one of humanity’s most devastating sources of pollution: plastics. This hugely positive step has the power to attack the problem as never before. But to achieve this goal, science needs to be front and centre in the negotiations.Plastic pollution is a massive problem. Some 400 million tonnes of the material is produced each year, a figure that could double by 2040. Of all the plastic that has ever been produced, only about 9% has been recycled and 12% incinerated. Almost all other waste plastic has ended up in the ocean or in huge landfill sites. More than 90% of plastics are made from fossil fuels. If left unchecked, plastics production and disposal will be responsible for 15% of permitted carbon emissions by 2050 if the world is to limit global warming to 1.5 °C above pre-industrial temperatures.Talks on the treaty are expected to take between two and three years and will be organized by the United Nations Environment Programme, based in Nairobi. A significant feature of the treaty is that it will be legally binding, like the 2015 Paris climate agreement and the Montreal Protocol, a 1987 treaty that led to the production and use of ozone-depleting substances being phased out.
How to globalize the circular economy
A team of negotiators from different regions is being established. By the end of May, they will start work on the treaty’s text. According to last week’s UN decision, these negotiators will consider “the possibility of a mechanism to provide policy relevant scientific and socio-economic information and assessment related to plastic pollution”. But they need to do more than just consider a mechanism. The UN must urgently set up a scientists’ group that can give the negotiators expert advice and respond to their questions. These science advisers would need to reflect the necessary expertise in the natural and social sciences, as well as in engineering, and represent different regions of the world.Nations want the plastics treaty to be more ambitious than most existing environmental agreements. Unlike the Montreal Protocol, which replaced around 100 ozone-depleting substances with ozone-friendly alternatives, countries have agreed that a plastics treaty must lock sustainability into the ‘full life-cycle’ of polluting materials. This means plastics manufacturing must become a zero-carbon process, as must plastics recycling and waste disposal. These are not straightforward ambitions, which is why research — and access to research — is so important as negotiations get under way.Most plastics are designed in a ‘linear’ one-way process: small, carbon-based molecules are knitted together with chemical bonds to make long and cross-linked polymer molecules. These bonds are hard to break, which makes plastics extremely long-lasting. They do not degrade easily and are difficult to recycle.Marine litter often grabs the headlines, but plastic pollution is everywhere. Landfill sites containing mountains of plastic blight our planet, and minuscule particles of plastic are found in even the most pristine environments. Such is the scale and persistence of plastics that they are now entering the fossil record. And a new human-made ecosystem — the plastisphere — has emerged that hosts microorganisms and algae1.
Chemistry can make plastics sustainable – but isn’t the whole solution
As negotiators get to work, they will need scientists to help them address several key questions. Which types of plastic can be recycled2,3? Which plastics can be designed to biodegrade, and under what conditions? And which plastics offer the best chances for reuse4? Moreover, social-sciences research will be essential to understanding the implications of — and inter-relationships between — the solutions that countries and industries will have to choose from. For example, new technologies and processes will have impacts on jobs. These impacts need to be studied so that risks to people’s livelihoods can be mitigated.Mapping out the implications of various approaches to greening the plastics industry will also require cooperation between governments, industry and campaign organizations — building on the cooperation that has brought the world to the start of negotiations.Plastics have made the modern world. They are a staple of daily life, from construction to clothing, technology to transport. But plastics use is also increasing at a rapid rate, and this is no longer tenable — around half of all plastics ever produced have been made since 2004.It is clear from the UN’s ongoing efforts to tackle climate change that it is not enough for a treaty to be legally binding. Signatories must also be held accountable, with regular reporting and checks on progress. Equally important is the need for science advice to be embedded in the talks from the earliest possible stage.Last week’s decision is the best start the planet could have had to tackling our plastics addiction. But as the hard work begins, decision-makers must be able to quickly and easily access the very best available evidence that research can provide.

World leaders agree to draw up ‘historic’ treaty on plastic wasteUN environment assembly resolution is being hailed as biggest climate deal since 2015 Paris accord World leaders, environment ministers and other representatives from 173 countries have agreed to develop a legally binding treaty on plastics, in what many described a truly historic moment.The resolution, agreed at the UN environment assembly in Nairobi, Kenya, calls for a treaty covering the “full lifecycle” of plastics from production to disposal, to be negotiated over the next two years. It has been described by the head of the UN Environment Programme (UNEP) as the most important multilateral environmental deal since the Paris climate accord in 2015.Approximately 7bn of the estimated 9.2bn tonnes of plastics produced between 1950 and 2017 are now waste. About 75% of that waste is either deposited in landfills or accumulating in terrestrial and aquatic environments and ecosystems.“Against the backdrop of geopolitical turmoil, the UN environment assembly shows multilateral cooperation at its best,” said Espen Barth Eide, the president of UNEA-5 and Norway’s minister for climate and the environment. “Plastic pollution has grown into an epidemic. With today’s resolution we are officially on track for a cure.”Inger Andersen, the director of the UN Environment Programme, tweeted: “We have just gavelled the resolution paving the way for global action to #BeatPlasticPollution. The most important environmental deal since the Paris accord.”“The work starts now!” she added.Andersen described the agreement as a “triumph by planet Earth over single-use plastics” but warned that the mandate did not grant stakeholders a “two-year pause”.“In parallel to negotiations over an international binding agreement, UNEP will work with any willing government and business across the value chain to shift away from single-use plastics, as well as to mobilise private finance and remove barriers to investments in research and in a new circular economy,” Andersen said.UN nations, which have been holding talks in Nairobi this week to discuss the terms for a treaty, agreed it should cover the production and design of plastic, not just waste. The resolution established an intergovernmental negotiating committee, tasked with drafting and ratifying the treaty. It will start work this year and aims to finish by 2024.The resolution introduces provisions to recognise waste pickers, a “groundbreaking development” that would affect millions of people, according to NGOs, and the acknowledgment of the role of indigenous peoples. It is the first time waste pickers, low-paid workers in developing nations who scavenge for recyclable plastic and other goods, have been recognised in an environmental resolution.NGOs described the resolution as a critical shift in international policymakers’ approach, which previously focused on plastic as a marine litter issue. The mandate recommends measures to tackle plastic production, predicted to almost quadruple by 2050 and take up 10-13% of the global carbon budget. They urged world leaders to show even more resolve in developing and finalising the details of the treaty over the next two years.“We stand at a crossroads in history when ambitious decisions taken today can prevent plastic pollution from contributing to our planet’s ecosystem collapse,” said Marco Lambertini, director general of WWF International. “But our work is far from over – world leaders must now show even more resolve in developing and implementing a treaty which addresses our current plastic pollution crisis and enables an effective transition to a circular economy for plastic.”Christina Dixon, the deputy ocean campaign lead at the Environmental Investigation Agency, said: “This resolution finally recognises that we cannot begin to address plastics in our ocean and on land without intervening at source. “Fundamentally, the plastics tap must be turned off if we are serious about tackling the problem,” she said.Dixon said the world was at the “start of a journey” towards securing a legally binding treaty.Niven Reddy, the Africa coordinator at the Global Alliance for Incinerator Alternatives, said: “This milestone could not have happened without a global movement pushing decision-makers every step of the way.”Joanne Green, a senior policy associate at Tearfund, said: “Today marks the first step towards justice for communities impacted by the burning and dumping of plastic waste. The recognition of waste pickers and the vital role they play in stopping plastic pollution is long overdue; governments must now ensure that they are given a prominent seat at the negotiating table.”The treaty will be accompanied by financial and technical support, including a scientific body to advise it, and the possibility of a dedicated global fund.The resolution was adopted with the conclusion of the three-day UNEA-5.2 meeting, attended by more than 3,400 delegates in person and 1,500 online participants from 175 UN member states, including 79 ministers and 17 high-level officials.There is growing public concern over plastic pollution. More than 60 countries already have implemented bans and levies on plastic packaging and single-use waste, aimed at reducing use and improving waste management.Plastic consumption in developed countries is 2.5 times higher per capita than in developing countries, according to the Planet Tracker thinktank.TopicsPlasticsSeascape: the state of our oceansPollutionUnited NationsEnvironmental activismGreen politicsnewsReuse this content

Unintentional PFAS in products: A “jungle” of contamination
Toxic PFAS are often added into consumer products to make items stain- or water-resistant. But mounting evidence indicates that many products made without the intentional addition of PFAS are also contaminated.
Researchers say these products may unintentionally become contaminated with PFAS, short for per- and polyfluoroalkyl substances, during the manufacturing or distribution process, raising concerns about entry points of PFAS into the supply chain that are not yet fully understood.
PFAS are linked to negative health outcomes including some cancers, reproductive problems, and birth defects, among others. Some manufacturers, such as cosmetics companies, will disclose the addition of the chemicals so consumers can determine their own exposure.
What’s harder to avoid, however, are those products that contain PFAS even when the manufacturers themselves may not know. Because of the widespread use of PFAS across industries, there are many ways that these “forever chemicals” can contaminate consumer goods—including manufacturing lubricants and coatings, misidentified raw materials, pesticides, personal protective equipment, and plastic packaging.
Marta Venier, an assistant professor at Indiana University who studies the transport of PFAS, told EHN that the high number of uses of PFAS in manufacturing means that products move through a “jungle” of possible contaminations before reaching the consumer.
PFAS contamination during manufacturing
Venier said it’s possible that coatings or lubricants used on manufacturing equipment or in factories can contain PFAS, which then transfer to the products made in such facilities. In such cases, the level of PFAS that is transferred to the product is low, but detectable, said Venier. Venier and Miriam Diamond, an environmental chemist at the University of Toronto, mentioned conveyor belt lubricant as a possible PFAS source.
Rainier Lohmann, an atmospheric chemist at the University of Rhode Island, also pointed to the possibility of contamination from slip agents—substances used in manufacturing to help mass-produced products slide easily out of molds.
In order to manufacture plastic goods, plastic pellets are melted, then extruded through a nozzle into a mold. Justin Boucher, the operations director of the Food Packaging Forum, thinks this could also be an entry point for PFAS. “To keep the plastic from gunking up these nozzles, they’re adding some kind of additives that contain PFAS,” he told EHN.
“You can basically go through almost the entire manufacturing chain and find several instances where you have this possibility that somewhere, PFAS has contaminated a product,” Lohmann told EHN. “It’s very difficult to figure out where that’s from, because they’re so ubiquitous.”
In other instances, said Venier, manufacturers may unknowingly create products with raw material that contains PFAS. “[Some] manufacturers buy their chemical products from intermediaries,” she said. “So they think that they are buying intermediary products that are PFAS free, when, in reality, they are not.”
There can also be PFAS in personal protective equipment or clothing that workers in manufacturing plants or food processing plants wear, particularly in gloves, which Lohmann and Venier said could be a possible area of concern.
To understand how PFAS in worker clothing and on equipment can accidentally contaminate products, Lohmann uses the analogy of a muffin tin with non-stick spray. Before baking, one sprays the muffin tin; after baking, the muffin is removed—with an oily sheen coating the bottom.
That ease of transfer makes it difficult to determine exactly how products get contaminated.
Incidental PFAS in food products
A 2017 study by the Green Science Policy Institute tested about 400 pieces of food packaging and found indications of PFAS in 40% of the items. (Credit: hewy/flickr) Because PFAS bioaccumulates in mammals, unintentional contamination can be a concern in animal products as well. A 2019 study at the U.S. Department of Agriculture examined levels of PFAS in the blood and tissue of cattle in a New Mexico herd that was accidentally exposed to the toxics in contaminated water. Given the widespread nature of PFAS contamination in water, it is likely that similar unintentional exposure is a concern for animal agriculture across the country, said Venier.PFAS are also used in different parts of agriculture and land management. PFAS in pesticides that contaminated water in Pepperell, Massachusetts, last May came from a liquid-repellent coating on the inside of the container used to store the pesticides. There is not always proper communication between companies in the chemical supply chain, said Boucher, which can make it impossible to know whether PFAS exist in certain agricultural inputs. PFAS can also unintentionally contaminate food through packaging, specifically when packaging is made from recycled materials. Because PFAS are such persistent chemicals, they can accumulate in recycled paper or wood pulp, either because the recycled material was coated in PFAS or came into contact with PFAS unintentionally.A 2017 study by the Green Science Policy Institute tested about 400 pieces of food packaging and found indications of PFAS in 40% of the items. If recycled, such PFAS-containing food packaging products would be reconstituted into other PFAS-containing products, perhaps without the knowledge of the manufacturer. “So if you’re allowed to use recycled pulp in food contact, paper, and board packaging, and you don’t have total control or oversight over what material was recycled, you don’t always know what chemicals were present,” said Boucher. Whether or not manufacturers are able to monitor the levels of PFAS in wood or paper pulp they are buying, he said, is unclear.
What manufacturers can do about PFAS contamination
Testing products for PFAS is still a relatively new field of science. However, some studies have indicated that non-intentional contamination is a growing problem.A 2021 study that tested hundreds of cosmetic products for PFAS found the chemicals in many products that didn’t list fluorinated compounds (an indicator of PFAS) in the ingredients, while other research has indicated that food packaging and paper products can contain non-intentionally added chemicals by way of certain inks and adhesives.In addition, recent testing by the wellness site Mamavation, partially supported by EHN.org, has found evidence of PFAS in makeup and clothing, including in many brands that are marketed as PFAS-free.The main problem, said Lohmann, is not necessarily manufacturer negligence but lack of awareness. Once manufacturers are aware that they are using PFAS in their manufacturing process, they can switch to alternative processing agents, like PFAS-free lubricants. There’s ample motivation for manufacturers to do this: “Being associated with PFAS is not something that most brands want to have these days,” he said. Boucher said manufacturers are “looking, and in some cases they’re finding, alternatives. My thinking is that the demand is going to grow for these PFAS-free alternatives across the whole processing chain.” While unintentional contamination usually results in low levels of PFAS on the consumer end, recognizing possible non-intentional entry points still provides an opportunity to limit exposure, which is especially important for people already experiencing high levels of PFAS. Additionally, said Diamond, the wide use of PFAS in manufacturing is already a concern for worker health. “We don’t spend enough time considering how the people who make our stuff are exposed,” she told EHN.From Your Site Articles
Plastic solutions in Kenya
A landmark UN resolution has been agreed to in Nairobi that could see an end to global plastics production. This comes almost five years after Kenya grabbed the attention of the world by banning the use of single-use plastics, though they are now slowly creeping back into the market. What are Kenyans doing to solve the problem of plastic pollution?
The UN is finally, maybe, doing something about plastic pollution
The UN has just signed a landmark agreement to reduce plastic pollution, in what some are calling the most important international environmental deal since the 2015 Paris agreement that targeted climate change.On Wednesday, marked by a gavel made from recycled plastics, representatives from 175 nations endorsed the agreement, which will act as the framework for discussions over the next two years. Worldwide, we produce 400 million tons of plastic a year, and that’s expected to double by 2040. If countries can stick to their commitments, it could lead to a massive reduction in single-use plastics, production levels, and ocean pollution.That’s a big “if”—while a lot of groups are cautiously optimistic, just like the Paris agreement, there are loopholes that countries could exploit. Here’s what you need to know about the agreement. What did the 175 countries actually agree to? “End plastic pollution: Towards an international legally binding instrument” is a series of loose resolutions promising to address the full life cycle of plastic products.It creates an intergovernmental negotiating committee, which will spend the next two years hashing out exactly how to tackle the plastic problem. Resolutions called for promoting sustainably designed products and materials, environmentally sound waste management, and financial support for developing countries.At the next UN Environment Assembly in 2024, the committee will finalize the agreement. “What we laid out was, in the easiest terms, a plan for a plan,” said Erin Simon, head of plastic waste and business at the World Wildlife Fund. But, she warned, “There could be plenty of time for countries to back off what they committed to.” What can we expect to see in the treaty? A lot could happen over the next two years. Right now, similar to the Paris agreement, the deal allows for countries to take voluntary approaches—meaning it will likely not be mandatory for them to meet their commitments. It also contains an open mandate that allows the intergovernmental negotiating committee to change the treaty before it’s signed, potentially watering it down. While the open mandate could present a potential loophole, Jane Patton, the plastics and petrochemicals campaign manager for the Center for International Law, said it allows the committee to improve the draft’s language, making issues like plastic’s toxicity to human health more explicit. “It’s about setting up a framework that countries feel empowered to take action on,” Simon said. “They are likely to take action if they have the opportunity to inform the process.”What can possibly go wrong?Just like with the Paris climate agreement, if the U.S. doesn’t uphold its end of the bargain, the rest of the world could follow suit. The U.S. is the largest plastic waste producer in the world, shipping off its unwanted garbage to developing nations.Plastic policy can sometimes gain bipartisan support, however. Even well-known environmental curmudgeon Donald Trump signed the Save Our Seas 2.0 Act, designed to fight coastal plastic debris, into law in 2020. Fortunately, the fact that plastic pollution is so visible is speeding up efforts to address it. “It’s something a bit more tangible as a problem than climate, because you can’t see greenhouse gases in the air, but I can see plastic pollution in the streets outside my house,” Patton said. Are the worst culprits finally going to be held to account? We’ll see. Plastics are derived from fossil fuels and chemicals, and, unsurprisingly, oil and chemical industries have been less enthusiastic about the treaty.Their strategy focuses on recycling, which diverts the conversation away from reducing plastic production and usage. With a recycling approach, consumers who lack access to proper recycling resources are held responsible for their plastic waste, while plastic producers can continue business as usual. Plus, if the resolution’s terms aren’t mandatory for governments, companies might not face meaningful restrictions, either.Perhaps surprisingly, companies that have been ranked as the world’s top plastic polluters, including PepsiCo, Nestlé, and Coca-Cola, have joined with dozens of others in a pre-UNEA statement supporting the treaty, using snazzy buzzwords that called for “a holistic, coordinated international response,” a “circular economy for plastics,” and a “robust governance structure to ensure countries’ participation and compliance.” Although the global agreement doesn’t enforce plastics restrictions yet, some companies have already made sustainability pledges. Nestlé commits that 100 percent of packaging will be recyclable or reusable by 2025. It may sound like progress, but environmental experts are skeptical.“Recycling doesn’t get to the root of the problems with plastic production,” said Jim Walsh, policy director at Food and Water Watch. “When you focus simply on issues of recycling and packaging management, you ignore all of the impacts of the petrochemical development and pollution that comes along with that.”The companies’ support could be due in part to a growing anti-plastics movement over the past two years. A 2021 Ipsos poll of more than 20,000 people in 28 countries found that 88 percent of respondents believe a global plastics treaty is important and 85 percent want manufacturers and retailers to be held responsible for plastic packaging. Over 2 million people signed WWF’s petition for a global plastics agreement ahead of negotiations.What’s so bad about plastic?Plastic pollution is an environmental nightmare. Annually, reports estimate that between 9 to 11 million metric tons of plastic are tossed into oceans, the equivalent of dumping a garbage truck full of plastic every minute. Forty percent of plastic produced is single-use, and disturbingly, after over a hundred years of production, only 9 percent of plastics has ever been recycled.Plastic garbage doesn’t really decompose—rather, it breaks down into smaller and smaller pieces, eventually becoming microplastics the size of sesame seeds. These synthetic crumbs act like magnets for surrounding chemical pollutants, attracting floating environmental contaminants and depositing them to unsuspecting hosts.That’s a major problem for humans. Besides the health effects from eating the plastic itself, humans are getting exposed to a host of hormone disruptors, carcinogens, and pollutants in our food, water, salt, beer, and seafood dinners. These toxins lead to serious health issues, including cancer, birth defects, cardiovascular diseases, diabetes, auto-immune conditions, neuro-degenerative diseases, and stroke. Fifth UN Environment Assembly President Espen Barth Eide told the committee on Monday his blood tests showed plastic compounds and chemicals in his body.Plastics also fuel climate change. A 2021 report from environmental group Beyond Plastics found that plastic is currently slated to outpace coal’s greenhouse gas emissions in the U.S. by 2030.“The fact that that isn’t addressed right now in any of the global multilateral environmental agreements is a significant issue,” Patton said. What happens next? Signing the treaty was a major step for taking some plastic out of the equation. “I wanna say I have all the hope,” Simon said. “The fact that we have come to consensus on the draft resolution so far showcases a collective desire to solve the plastic pollution crisis together.”But nations, companies, NGOs, and consumers shoulder greater responsibility to make good on its promises over the next few years. Several of the member nations have already started to take action. In 2019, the European Union began limiting certain single-use plastics, restricting their sale when sustainable alternatives were easily available. Kenya, the UN host country, banned single-use plastics in protected natural areas in 2020. “This is a problem that the world cannot ignore,” Patton said. “It is a problem that has urgent implications for human health and the environment, and we have to move quickly on this issue.”
