When plastic debris pollutes soil ecosystems, some insects may play a role in spreading it by breaking it down into microplastic particles. A new study sheds light on this dynamic by looking at a variety of soil invertebrates—such as the Zophobas morio beetle larva shown here—and their taste for polystyrene. (Photo by Max Helmberger)

Microplastics permeate the world. They can float through the air and have been found in Antarctic ice, the deep ocean, drinking water, and inside an array of animals. Microplastic pollution, mostly in the oceans, has been getting a lot of attention in the last few years but microplastics’ ubiquity means that scientists researching them have to find ways to limit contamination—and assess its extent when it inevitably happens. Max Helmberger, a Ph.D. student in entomology at Michigan State University, has researched several soil-dwelling organisms’ ability to create microplastics from larger plastic debris. He says labs have had to come up with “all sorts of creative solutions” to the contamination problem, with at least one dying all their lab coats bright pink so it would be obvious when bits invade a sample. Helmberger says, “Being persnickity is kind of a must in microplastic research because microplastics are everywhere.”
Max Helmberger
Microplastics come in two basic forms: primary and secondary. Primary microplastics are ones that are manufactured in sizes smaller than 5 millimeter (think sesame seed). Nurdles, the pre-production pellets used to make plastic products, are an example of a primary microplastic. Secondary microplastics are tiny bits that have broken off larger pieces. It is this second type of microplastic that Helmberger and colleagues recently studied in relation to insects and other invertebrates. Findings from their research were published in February in the open-access Journal of Insect Science.
Helmberger and his colleagues wanted to look at an array of different types of soil-dwelling organisms and assess their ability to fragment plastic in a fairly short period of time. His chosen animals were Acheta domesticus (a house cricket), Oniscus asellus (an isopod, sometimes known as a sowbug or woodlouse), Zophobas morio larvae (a beetle), and Cornu aspersum (a snail). Helmberger put each animal in an “arena”—a small glass jar. The bottom was filled with plaster of Paris and topped with sand that had been heated to 500 degrees Celsius to burn off organics and plastics. The animals went into the jar with pieces of both pristine and weathered polystyrene, along with one oat flake of real food to sustain them. He left them there for 24 hours.
To explore the role insects and other invertebrates may play in spreading plastic pollution in soil ecosystems by breaking it down into microplastic particles, researchers placed various organisms—such as this house cricket (Acheta domesticus)—in glass-jar arenas with a small amount of food and a piece of polystyrene foam for 24 hours. Afterward, the researchers counted the number of microplastic particles in the animal feces, the sand, and within the dead animal itself. (Photo by Max Helmberger)

Opinion: Biodegradable beads help reduce Mardi Gras plastic pollution
The floats have passed through, the barricades have been taken down and the king cake has been eaten. While we recover from the exhaustion of Mardi Gras, most of us aren’t thinking about the environmental effects of this Louisiana tradition, but we should be.Mardi Gras necklaces have been thrown at parades since 1871, originally made of glass beads and tossed with doubloons and other knickknacks. The glass has now been replaced with plastic, and the necklaces are thrown alongside stuffed animals, cups, hats, candy and more. The tradition of Mardi Gras beads is well known throughout the country, but what is less known is what happens to those beads after the parades are over.In New Orleans, parades follow routes all through the city, and the loaded storm drains are evidence of the effects these seemingly harmless beads have on the environment. In 2018, New Orleans city workers collected 93,000 pounds of Mardi Gras beads from the drainage system. That’s almost 47 tons.
Not only do the beads block flood waters from flowing through the drains, but they also release small amounts of lead into soil and water. Children take home these colorful necklaces of toxic metal and flame retardants, which have been linked to birth defects, asthma, reproductive issues, liver toxicity, learning disabilities and cancer.While it is important to keep up Mardi Gras traditions, it is far more important to protect parade goers, bead collectors and the environment. Drainage systems are in place as protection from flooding and pollution, the functionality of which New Orleans desperately needs.
To fight back against Mardi Gras waste, the Young Leadership Council of New Orleans launched the Mardi Gras Recycling Initiative. This initiative encourages people to reuse their beads, invest in sustainable beads and volunteer to clean up after the Mardi Gras festivities. The city also offers recycling along parade routes and donation sites though The Arc of Greater New Orleans.More recently, there has been a push for the use of sustainable beads. As a response, Noble Plastics—a company based in St. Landry parish—has assisted LSU professor Naohiro Kato in the creation of a biodegradable bead. The beads themselves are made of microalgae grown in tanks on campus, which is then processed and dried in Kato’s lab. The microalgae are paired with compostable plastic, molded and strung on hemp string. While untreated plastic beads take many years to decompose, Kato’s beads will degrade in less than two years.As of now, a single sustainable necklace costs a whopping $5, but this didn’t stop the Krewe of Tucks and Krewe of Freret from stocking up this past Mardi Gras season. 500 strands of Kato’s beads were thrown in New Orleans this year. If the popularity of these microalgae beads grow, Kato hopes he can mass produce them and reduce prices to between 20 and 50 cents per necklace.Kato’s new biodegradable bead provides a way to protect Mardi Gras traditions while also protecting our state’s environment and residents. Sustainable parade practices help us highlight the green in the Mardi Gras colors we cherish so dearly in Louisiana.Mia Coco is a 19-year-old political communications student from Alexandria.
Rush of lawsuits over plastic waste expected after ‘historic’ deal
Rush of lawsuits over plastic waste expected after ‘historic’ dealLike Paris climate agreement, treaty could provide tool to hold firms and states to account, say legal experts A series of lawsuits against plastic producers and governments is expected after a “historic” international agreement on waste, say legal experts.Last week, world leaders agreed to draw up a legally binding treaty over the next two years that covered the full lifecycle of plastics from production to disposal. The move was described by the head of the UN Environment Programme as the most important multilateral environmental deal since the Paris agreement in 2015.And, like its climate counterpart, the new treaty could provide an essential tool to hold governments and companies accountable for their environmental impacts.An imminent case in the Philippines could set an important precedent. Last year, a coalition of individuals and environmental groups led by the marine conservation group Oceana Philippines filed a petition accusing the Philippine government of failing to tackle the “unabated production, use and disposal of plastic” over the past two decades.The group claims a law requiring the country’s public waste body to review, update and enforce a list of products that are not environmentally friendly has never been implemented despite being passed in 2001. The result of this, it say, is “the unabated emission of millions of tons of plastic waste into every nook and cranny of the Philippine archipelago”.The petitioners, who include people who are catching fewer fish, having trouble conceiving or being affected by worsening floods aggravated by plastic pollution, say the government’s inaction is breaching their constitutional right to a healthy environment.The Philippine supreme court has accepted the case, which goes to trial later this month.Carroll Muffett, the president of the US-based Center for International Environmental Law, said it was “beyond any doubt” there would be more lawsuits on plastics in future, pointing to the “small but accelerating” body of litigation already in North America.The coffee company Keurig Green Mountain recently agreed settlements in both the US and Canada with a consumer and regulator respectively after being challenged on claims about the recyclability of its disposable coffee pods. The company paid out millions of dollars and has to change the language it uses on its packaging.Earth Island Institute, a California-based environmental group, has filed three separate lawsuits against producers of plastic goods. In 2020, it began suing Coca-Cola, Pepsi, Nestlé and other large companies for creating a plastic pollution “nuisance”. The following year Earth Island Institute brought another lawsuit against Coke as well as BlueTriton Brands (formerly Nestlé Waters North America), claiming the companies falsely portrayed themselves as environmentally friendly despite being huge plastic polluters. The companies argue they are all taking action to reduce their plastic use, improve collection and try to find policy resolutions with legislators.All three cases are still pending, but at least two will be heard in state courts, which in general have been more sympathetic than federal courts towards environmental litigants.According to Rosa Pritchard, a plastics lawyer at the environmental law charity ClientEarth, plastics-related litigation is already on the rise. “Plastics production – big oil’s plan B – is increasingly in the spotlight for its contribution to climate change.”ClientEarth is taking legal action to stop the petrochemicals group Ineos building a giant plastics plant in Belgium,Pritchard said the Paris agreement had “provided an essential tool” to hold governments and corporations accountable for their contribution to climate change. “A robust treaty on plastics could also have this impact” alongside further waste and climate laws being introduced across Europe, she added.As well as using the law to challenge plastic production, ClientEarth will be focusing its efforts on industry greenwashing. It has already reported Ahold Delhaize, one of the world’s largest grocery retail groups, to the Dutch financial regulator for allegedly failing to disclose key information on the company’s use of plastics or to report plastic-related risk to its investors. The company has said that it reports annually on the progress it is making with regards to reducing its plastic use and is focusing on those areas where it can have a direct impact, such as improving packaging, phasing out single-use plastic and recycling plastic waste from its sites.Muffett said: “Communities and states affected by plastics are going to be learning from the lessons of climate litigation and looking at the industries and actors that are playing a role in that crisis. A lot of different people are affected in very different ways, and that means that the potential avenues for litigation are actually very substantial and very diverse.”In a stark parallel to the misinformation campaigns on climate crisis supported by the fossil fuel industry, Muffett said there was mounting evidence that plastic producers had known for a very long time it accumulated in the environment and that they had sought to shift the blame to consumers: “It’s just a matter of when the additional dots get connected.”Muffett said the commitment to make a legally binding plastics treaty signalled an important shift in political and public debate. “It means that the era of unrestricted plastic production, use and disposal has a limited lifetime, so everyone working in those sectors is going to have to address that reality very soon – and if they fail to do that a new litigation risk will arise.”TopicsPlasticsnewsReuse this content

In a first, California plans to clean up microplastics
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 waste
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
