While Shell is scheduled to open an ethane cracker this year in Beaver County, north of Pittsburgh, a possible second cracker in the region faces an uncertain future. 
These industrial plants use ethane from unconventional gas drilling in the region to create plastics. 
The Ohio Environmental Protection Agency just renewed the wastewater discharge permit for PTTGC America, of Thailand, for its proposed facility in Belmont County, Ohio, about 70 miles southwest of Pittsburgh. It would produce 1.5 million tons of plastics per year. 
Citizen comments on the permit mention that the River provides drinking water for roughly 5 million people and that there are concerns about the types of chemicals allowed to be discharged by the plant. 
Ohio EPA said its standards are protective of drinking water and human health and that there is a water quality monitoring program on the Ohio River. 
PTTGC is also in the process of drafting an application for an air permit from Ohio EPA to modify one that expired on February 24. 
Still, it is uncertain if the company will build the plant. 
“The real movement will come once the company identifies a partner, which hasn’t happened yet. That’s been the focus since the pandemic,” said spokesperson Dan Williamson.

An emerging domain of research shows that plastic consumption and pollution harms human health — particularly for the world’s lower-income communities.This builds on a growing field of research revealing the dangers of plastic on the environment — especially marine ecosystems. Of the over 8 billion tons of plastic produced since the 1950s, less than 10 percent has been recycled.“Plastic threatens human health at every stage of its production pipeline — from the extraction of the fossil carbon, oil and gas, that is plastic’s main constituent, to its manufacture, use and disposal,” said Philip Landrigan, director of the Global Observatory on Pollution and Health and lead author of the Lancet Commission on pollution and health.The connection between plastics and health was also highlighted in Africa by researchers from Stanford and the Technical University of Mombasa. After decades of hunting for mosquito-borne viruses in coastal Kenya, they received one of their greatest tips from a group of elementary schoolchildren.The scientists had been trying to uncover the breeding grounds of mosquitoes causing a number of illnesses that regularly sicken over half of Kenya’s coastal population — including dengue, chikungunya and others that can cause severe fevers, headaches, rashes, joint pain, life-threatening bleeding and death.With these diseases on the rise, researchers were teaching schoolchildren about the life stages and habitats of insects that serve as vectors. On a homework assignment to find immature forms of mosquitoes in their communities, the children discovered something unexpected — disease-carrying mosquitoes breeding in nests of plastic trash around their homes.“We were astounded,” said Stanford pediatrician and researcher Desiree LaBeaud, who led the project. “The children’s discovery helped us realize that the majority of mosquitoes were breeding in plastic trash and other containers littering streets and people’s yards.”Environment and health“We realized that we needed to look far beyond just treating the sick,” said LaBeaud, who is senior author on an upcoming publication in PLOS Neglected Tropical Diseases on the topic. “To stop these diseases at their source, we needed to tackle the plastic problem.”Plastics are closely tied to climate change, which the National Academy of Medicine (NAM) has recognized as “one of the most pressing existential threats to human health,” in the words of NAM President Victor J. Dzau. Plastics use the same amount of oil as the entire aviation industry — and are expected to more than triple in their oil consumption in the next 30 years.Moreover, the pollution caused by petrochemical plants — which are most often in lower-income settings — threaten the health of communities. “Plastic manufacture is inequitably distributed, with virtually all plastic production facilities located either in low- and mid-income countries or in poor and minority communities within high-income countries,” Landrigan pointed out.Disposing of plastic waste also poses challenges. In places such as sub-Saharan Africa, as much as three quarters of all waste is burned, releasing toxic compounds and carcinogens into the air.The infectious-disease research in coastal Kenya is a critical new dimension. Plastic pollution is exacerbating an already dire public health challenge — over 50 percent of people in coastal Kenya are regularly exposed to dengue and chikungunya, and at least 10 percent of febrile illness in the region is probably because of undiagnosed mosquito-borne viral infections. This pattern seems to be widespread — similar findings have emerged in South America and Asia.The problem is not only the potentially deadly diseases themselves. With symptoms for some illnesses such as chikungunya lasting for up to months or years, getting sick could also mean missing school and days of work — and communities being kept in poverty, creating what some scholars call the “disease-poverty trap.”“The case of plastics vividly illustrates how the industrial practices of the high-income world are intimately tied to the health and development of lower-income communities around the globe,” LaBeaud said. “Maintaining a healthy planet requires thinking carefully about how we produce, consume, and waste — knowing that downstream health impacts, especially on marginalized communities, won’t always be immediately apparent.”Fighting a growing problemCombating the plastic pollution in Kenya and other African countries involves addressing both exported recycling from high-income countries and an influx of new plastic products, especially single-use materials.Kenya, along with 95 other countries, received more than 1 billion pounds of foreign plastic waste from U.S. exporters in 2019 alone. This roughly equates to a line of 18-wheeler semi-trucks full of plastic trash backed up for about 350 miles, stretching nearly the entire length of Florida. And it’s not just plastic trash imports — Nairobi also saw a quadrupling in plastic consumption over the same 25-year period that its population only tripled.In response, Kenya banned single-use plastic bags in 2017 and banned all single-use plastic in protected natural sites in 2020. This is part of a larger movement to reduce plastic waste in Africa. The African Union, for example, has set a goal that 50 percent of waste used in African cities be recycled by 2023.Communities across Africa have also started exploding with locally designed solutions — exploring opportunities to rethink waste management and recycling in ways that also support local economies.For example, LaBeaud and Kenyan partners launched a nonprofit organization, HERI-Kenya, to engage policymakers, communicate the plastic-disease connection, and build business opportunities that allow for more locals to make a living collecting and recycling trash. This, they hope, can build the foundation for what is known as a circular economy for plastics, where the reuse and recycling of materials create a sustainable system of zero waste.“When we remove plastic litter, we not only improve local environments — we improve human health, beautify our community, support local entrepreneurs and boost tourism,” said Francis Mutuku, a researcher at the Technical University of Mombasa and LaBeaud’s long-term collaborator. “Everyone stands to gain.”Yet, despite the will to act, activists and lawmakers in Africa have found that the solution is not as simple as recycling or banning plastics.With fossil fuels increasingly falling out of favor, actors such as the American Chemistry Council (ACC) and large oil companies are reportedly moving toward a new strategy, opting to turn oil into plastics and distribute them to external markets, including countries in Africa. While the ACC has denied efforts to undermine bans on single-use plastics in places such as Kenya, many of the companies it represents are still expanding their production and distribution of plastics.In 2019, Chevron Phillips Chemical, a joint venture partially owned by Chevron, called petrochemical collaborations with Qatar Petroleum, now called QatarEnergy, “some of the safest and most successful assets in Chevron Phillips Chemical’s global portfolio” — including a new $8 billion project to develop a Gulf Coast petrochemical plant.“From delivering fresh water and preventing food waste to supplying medical products used every day in hospitals worldwide, our materials help people live prosperous and healthy lives,” Chevron Phillips Chemical said in an emailed statement.“With growing recognition around the negative health and environmental consequences of plastics, we do need to ask — why produce more?” Stanford Center for Innovation in Global Health Director Michele Barry said. “Where are these new chemical plants being built, and which communities are the intended recipients of these products?”Beyond recyclingRecycling is one of the most talked-about solutions for the plastics crisis.“ACC supports scaling up advanced recycling,” said Stewart Harris, senior director of Global Plastics Policy at the ACC, in an email, referring to recycling technology that breaks down used plastics into their basic building blocks to create new, often reusable, products. “Since 2017, 70 advanced recycling projects representing over $7 billion in investments have been announced or are already operating.”A wide range of companies have begun to invest in improved waste collection and recycling — for example, Chevron Phillips Chemical’s investments in circular plastics and Coca-Cola’s PETCO campaign in southern and eastern Africa.“We encourage responsible disposal of PET packaging and recycling of the same to create a circular economy, which has an economic impact on those involved throughout the recycling value-chain,” said Scott Leith, a spokesperson for Coca-Cola, who acknowledged that the challenge of plastic waste requires multiple approaches.While some local community organizations, such as Clean Up Kenya, have criticized Coca-Cola’s approach, advocates have noted that initiatives such as this one could allow simultaneous improvements in waste infrastructure, financial incentives for collectors and worker safety.“Partnerships between governments and the private sector are critical to achieving universal access to waste collection, which forms the foundation of a circular economy,” said Harris, in an emailed statement. Other groups such as the Alliance to End Plastic Waste are also trying to engage a variety of companies and organizations to accelerate community-engaged solutions.Yet researchers and policymakers have pointed out that recycling is no silver bullet, because of limitations in recycling capability and the environmental costs of producing plastics in the first place.Kenyan activists, including Clean Up Kenya, are calling for more comprehensive upstream solutions — including banning single-use plastic bottles overall.A 2020 report by SYSTEMIQ frames plastic collection and recycling as just one dimension of a strategy to reduce 80 percent of plastic pollution by 2040. Other critical channels of action noted in the report include reducing plastic consumption, substituting materials, redesigning products, securely disposing of the near-quarter of plastic that cannot be recycled — and, particularly relevant to Kenya’s plastic challenges, reducing “waste exports into countries with low collection and high leakage rates by 90%.”“There is an urgent need to simultaneously rein in plastic production and use in countries at every level of income,” Landrigan said.“We can’t recycle our way out of our global plastic problem,” Barry said. “Without a fundamental reimagining of global industrial practices, we will continue to see dire impacts on the climate, the planet and our health.”Erika Veidis serves as the planetary health program manager for the Stanford Center for Innovation in Global Health, where she leads the Action Lab for Planetary Health, a program focused on moving Stanford environmental and health research to solutions.Jamie Hansen serves as communications manager for the Stanford Center for Innovation in Global Health, helping to amplify the work of the center and its fellows through storytelling and multimedia communications.

Share on PinterestMIcroplastics’ newest vessel, according to new research, is human blood. pcess609/Getty ImagesScientists have been concerned about possible harm from microplastics for many years.In a new study, researchers developed a method of detecting microplastics in human blood.The scientists found microparticles of four common plastics in blood samples from 17 out of 22 healthy adults.Further research could determine whether microplastics in the blood will impact health.Plastics are everywhere. Although, in theory, much of it can be recycled, a lot of it ends up in landfills, or worse, in watercourses and marine ecosystems.Many people are too familiar with distressing images of turtles and dolphins trapped in plastic bags or fishing nets. But there is a less visible effect — microplastics, tiny plastic particles formed when plastics break down and during commercial product manufacturing. Several studies have found evidence of plastics in the human body. One revelation came after scientists detected plastic additives such as bisphenol A (BPA) and phthalates in human urine. Researchers have also found microplastics in human feces. However, until now, no published study has directly examined the effect of these tiny plastic specks on human health.In a new study published in the journal Environment International, researchers in the Netherlands developed a method of analyzing human blood to detect microplastics. They then used this method to analyze blood from 22 healthy volunteers.Microplastics are specks of plastic. By definition, they are less than 5mm in any dimension, but many are invisible to the naked eye. There are two types of microplastics: primary microplastics and secondary microplastics. The former are the particles used in some cosmetics, and the latter comes from the breakdown products of larger plastic items.Much concern about microplastics has previously focused on their effect on the marine environment, as they are found in oceans worldwide. Many marine organisms, such as fish and shellfish, have been found to contain microplastics. “It’s highly probable given the prevalence of microplastics in air, water, wildlife, the food chain, that they will also be entering the human body, but the technical difficulties of measuring microplastic particles in the human body has made it hard to confirm this.”– Prof. Tamara Galloway, chair in ecotoxicology at the University of Exeter, the U.K.For this study, the researchers looked for particles that could be absorbed across membranes in the human body. They filtered the blood to collect any plastic particles between 700 nanometers(nm) and 500,000nm. To avoid any plastic contamination, the researchers used glass fiber filters.The researchers looked for five common plastics: The samples from the filters were processed by double-shot pyrolysis to produce chromatograms from which scientists could identify the contents.“Human biomonitoring methods for measuring plastics additives have been available for several years […] But measuring microplastics, especially at the small size that would likely circulate in blood vessels (7 microns), is very hard,” Prof. Galloway told Medical News Today.“This paper is good news because it describes a method that is sensitive enough to do this in blood samples and combines size fractionation and mass measurements,” she added.More than three-quarters of the blood samples contained a quantifiable mass of plastic particles. The researchers found PET — which most drinks bottles are made from — in the blood of more than half of those tested. They did not detect PP in any of the samples.Researchers found at least 3 different types of plastic in some blood samples.Prof. Galloway was unsurprised by the findings: “The fact that just about everyone has microplastic in their blood isn’t so surprising when you consider that just about everyone has plastics additives in their bodies.”The researchers suggest several ways the plastics may have entered the bloodstream — via air, food, water, personal care products such as toothpaste and lip gloss, dental polymers, and tattoo ink residues. What happens to the microplastics once they enter the bloodstream is unclear.In vitro studies have shown the effects of microplastics on cells. A recent study in Germany found that microplastic particles can destabilize lipid membranes — the barriers that surround all cells — which may affect their functioning. Another study found that microplastics had many effects on cells, including cell death.The current study was based on a sample size of only 22 people, so the authors stress the need for further research: “It remains to be determined whether plastic particles are present in the plasma or are carried by specific cell types.” However, they believe that “[i]t is scientifically plausible that plastic particles may be transported to organs via the bloodstream.”What effect they might have on organs is, as yet, unknown.

As long as there has been marine life, there has been marine snow — a ceaseless drizzle of death and waste sinking from the surface into the depths of the sea.The snow begins as motes, which aggregate into dense, flocculent flakes that gradually sink and drift past the mouths (and mouth-like apparatuses) of scavengers farther down. But even marine snow that is devoured will most likely be snowfall once more; a squid’s guts are just a rest stop on this long passage to the deep.Although the term may suggest wintry whites, marine snow is mostly brownish or grayish, comprising mostly dead things. For eons, the debris has contained the same things — flecks from plant and animal carcasses, feces, mucus, dust, microbes, viruses — and transported the ocean’s carbon to be stored on the seafloor. Increasingly, however, marine snowfall is being infiltrated by microplastics: fibers and fragments of polyamide, polyethylene and polyethylene terephthalate. And this fauxfall appears to be altering our planet’s ancient cooling process.Every year, tens of millions of tons of plastic enter Earth’s oceans. Scientists initially assumed that the material was destined to float in garbage patches and gyres, but surface surveys have accounted for only about one percent of the ocean’s estimated plastic. A recent model found that 99.8 percent of plastic that entered the ocean since 1950 had sunk below the first few hundred feet of the ocean. Scientists have found 10,000 times more microplastics on the seafloor than in contaminated surface waters.Marine snow, one of the primary pathways connecting the surface and the deep, appears to be helping the plastics sink. And scientists have only begun to untangle how these materials interfere with deep-sea food webs and the ocean’s natural carbon cycles.“It’s not just that marine snow transports plastics or aggregates with plastic,” Luisa Galgani, a researcher at Florida Atlantic University, said. “It’s that they can help each other get to the deep ocean.”Marine snow-makingPlastic waste washing up on a beach in Bali, Indonesia. Surface surveys have accounted for only about one percent of the ocean’s estimated plastic.Agung Parameswara/Getty ImagesThe sunlit surface of the sea blooms with phytoplankton, zooplankton, algae, bacteria and other minuscule life, all feeding on sunbeams or one another. As these microbes metabolize, some produce polysaccharides that can form a sticky gel that attracts the lifeless bodies of tiny organisms, small shreds of larger carcasses, shells from foraminifera and pteropods, sand and microplastics, which stick together to form larger flakes. “They are the glue that keeps together all the components of marine snow,” Dr. Galgani said.Marine snowflakes fall at different rates. Smaller ones have a more languid descent — “as slow as a meter a day,” said Anela Choy, a biological oceanographer at Scripps Institution of Oceanography at the University of California, San Diego. Bigger particles, such as dense fecal pellets, can sink quicker. “It just skyrockets to the bottom of the ocean,” said Tracy Mincer, a researcher at Florida Atlantic University.Plastic in the ocean is constantly being degraded; even something as big and buoyant as a milk jug will eventually shed and splinter into microplastics. These plastics develop biofilms of distinct microbial communities — the “plastisphere,” said Linda Amaral-Zettler, a scientist at the Royal Netherlands Institute for Sea Research, who coined the term. “We sort of think about plastic as being inert,” Dr. Amaral-Zettler said. “Once it enters the environment, it’s rapidly colonized by microbes.”A sample of South Atlantic water containing plankton and microplastics. Ocean plastics commonly develop a filmy “plastisphere” of distinct microbial communities.Morgan Trimble/AlamyMicroplastics can host so many microbial hitchhikers that they counteract the natural buoyancy of the plastic, causing their raft to sink. But if the biofilms then degrade on the way down, the plastic could float back up, potentially leading to a yo-yoing purgatory of microplastics in the water column. Marine snow is anything but stable; as flakes free-fall into the abyss, they are constantly congealing and falling apart, rent by waves or predators.“It’s not as simple as: Everything’s falling all the time,” said Adam Porter, a marine ecologist at the University of Exeter in England. “It’s a black box in the middle of the ocean, because we can’t stay down there long enough to work out what’s going on.”To explore how marine snow and plastics are distributed in the water column, Dr. Mincer has begun to sample deeper waters with a dishwasher-size pump full of filters that dangles on a wire from a research boat. The filters are arranged from big mesh to small to filter out fish and plankton. Running these pumps for 10 hours at a stretch has revealed nylon fibers and other microplastics distributed throughout the water column below the South Atlantic subtropical gyre.But even with a research boat and its expensive and unwieldy equipment, an individual piece of marine snow is not easily retrieved from deep water in the actual ocean. The pumps often disturb the snow and scatter fecal pellets. And the flakes alone offer little insight into how fast some snows are sinking, which is vital to understanding how long the plastics linger, yo-yo or sink in the water column before settling on the seafloor.“Is it decades?” Dr. Mincer asked. “Is it hundreds of years? Then we can understand what we’re in here for, and what kind of problem this really is.”Instant marine snowExperimental “mesocosms” created by the researcher Luisa Galgani and her team on the Greek island of Crete, to mimic and observe marine snow. “In the mesocosm, you are manipulating a natural system,” she said.Luisa Galgani, Chiara Esposito, Paraskevi PittaTo answer these questions, and work within a budget, some scientists have made and manipulated their own marine snow in the lab.In Exeter, Dr. Porter collected buckets of seawater from a nearby estuary and loaded the water into continuously rolling bottles. He then sprinkled in microplastics, including polyethylene beads and polypropylene fibers. The constant churning, and a squirt of sticky hyaluronic acid, encouraged particles to collide and stick together into snow.“We obviously don’t have 300 meters of a tube to make it sink,” Dr. Porter said. “By rolling it, what you’re doing is you’re creating a never-ending water column for the particles to fall through.”After the bottles rolled for three days, he pipetted out the snow and analyzed the number of microplastics in each flake. His team found that every type of microplastic they tested aggregated into marine snow, and that microplastics such as polypropylene and polyethylene — normally too buoyant to sink on their own — readily sank once incorporated into marine snow. And all the marine snow contaminated with microplastics sank significantly faster than the natural marine snow.Tubes of marine snow in the lab of Adam Porter at the University of Exeter in England. “It’s not as simple as: Everything’s falling all the time,” Dr. Porter said.Adam PorterDr. Porter suggested that this potential change of the speed of the snow could have vast implications for how the ocean captures and stores carbon: Faster snowfalls could store more microplastics in the deep ocean, whereas slower snowfalls could make the plastic-laden particles more available to predators, potentially starving food webs deeper down. “The plastics are a diet pill for these animals,” said Karin Kvale, a carbon cycle scientist at GNS Science in New Zealand.In experiments in Crete, with funding from the European Union’s Horizon 2020 research program, Dr. Galgani has tried mimicking marine snow on a larger scale. She dropped six mesocosms — huge bags that each contained nearly 800 gallons of seawater and recreated natural water movement — in a large pool. Under these conditions, marine snow formed. “In the field, you mostly make observations,” Dr. Galgani said. “You have so little space and a limited system. In the mesocosm, you are manipulating a natural system.”Dr. Galgani mixed microplastics into three mesocosms in an attempt to “recreate a sea and maybe a future ocean where you can have a high concentration of plastic,” she said. The mesocosms laden with microplastics produced not just more marine snow but also more organic carbon, as the plastics offered more surfaces for microbes to colonize. All this could seed the deep ocean with even more carbon and alter the ocean’s biological pump, which helps regulate the climate.“Of course, it’s a very, very big picture,” Dr. Galgani said. “But we have some signals that it can have an effect. Of course, it depends on how much plastic there is.”A plastic feastVampire squids, which live in deep waters, were collected from a contaminated patch of the Atlantic Ocean and found to have alarmingly high levels of plastic in their stomachs. Steve Downer/Science SourceTo understand how microplastics might travel through deep-sea food webs, some scientists have turned to creatures for clues.Every 24 hours, many species of marine organism embark on a synchronized migration up and down in the water column. “They do the equivalent of a marathon every day and night,” Dr. Choy said. Guilherme V.B. Ferreira, a researcher at the Rural Federal University of Pernambuco in Brazil, wondered: “Is it possible they are transporting the plastics up and down?”Dr. Ferreira and Anne Justino, a doctoral student at the same university, collected vampire squids and midwater squids from a patch of the tropical Atlantic. They found a plethora of plastics in both species: mostly fibers, but also fragments and beads.This made sense for midwater squids, which migrate toward the surface at night to feed on fish and copepods that eat microplastics directly. But vampire squids, which live in deeper waters with fewer microplastics, had even higher levels of plastic, as well as foam, in their stomachs. The researchers hypothesize that the vampire squids’ primary diet of marine snow, especially meatier fecal pellets, may be funneling plastics into their bellies.“It’s very concerning,” Ms. Justino said. Dr. Ferreira said: “They are one of the most vulnerable species for this anthropogenic influence.”Ms. Justino has excavated fibers and beads from the digestive tracts of lanternfish, hatchetfish and other fish that migrate up and down in the mesopelagic, 650 to 3,300 feet down. Some microbial communities that settle on microplastics can bioluminesce, drawing in fish like a lure, said Dr. Mincer.In the Monterey Bay Canyon, Dr. Choy wanted to understand if certain species of filter feeders were ingesting microplastics and transporting them into food webs in deeper water. “Marine snow is one of the major things that connects food webs across the ocean,” she said.The large, mucusy house of a deep-sea larvacean. When the larvaceans move out, their microplastic-laden houses sink into the deep.NOAA Ocean ExplorationDr. Choy zeroed in on the giant larvacean Bathochordaeus stygius. The larvacean resembles a tiny tadpole and lives inside a palatial bubble of mucus that can reach up to a meter long. “It’s worse than the grossest booger you’ve ever seen,” Dr. Choy said. When their snot-houses become clogged from feeding, the larvaceans move out and the heavy bubbles sink. Dr. Choy found that these palaces of mucus are crowded with microplastics, which are funneled to the deep along with all their carbon.Giant larvaceans are found across the world’s oceans, but Dr. Choy emphasized that her work was focused on the Monterey Bay Canyon, which belongs to a network of marine protected areas and is not representative of other, more polluted seas. “It’s one deep bay on one coast of one country,” Dr. Choy said. “Scale up and think about how vast the ocean is, especially the deep water.”Individual flakes of marine snow are small, but they add up. A model created by Dr. Kvale estimated that in 2010, the world’s oceans produced 340 quadrillion aggregates of marine snow, which could transport as many as 463,000 tons of microplastics to the seafloor each year.Scientists are still exploring exactly how this plastic snow is sinking, but they do know for sure, Dr. Porter said, that “everything eventually sinks in the ocean.” Vampire squids will live and die and eventually become marine snow. But the microplastics that pass through them will remain, eventually settling on the seafloor in a stratigraphic layer that will mark our time on the planet long after humans are gone.

More than two decades after the publication of Our Stolen Future, what is the state of research on endocrine disruptors? Are those sneaky contaminants continue to interfere with our hormones?

In the book, scientists Theo Colborn and John Peterson Myers, along with journalist Dianne Dumanoski, shed light on the terrible effects that many environmental contaminants are having on the health of living things, as they interact with the hormonal system, also called the endocrine system.

These chemicals, called endocrine disruptors, can mimic or interfere with the body’s hormones, including thyroid hormones, estrogen, testosterone, etc. Endocrine disruptors can impair the development and proper functioning of the reproductive, nervous and immune systems in humans and animals, and can affect future generations.

One of us, Valérie, holds the Canada Research Chair in Ecotoxicogenomics and Endocrine Disruption. The other, Isabelle, studies the environmental causes of breast cancer. Together, we founded the Intersectorial Centre for Endocrine Disruptor Analysis (ICEDA) at the Institut national de la recherche scientifique.

Along with our colleagues, we recently published a collection of articles that review the scientific literature on endocrine disruptors and their deleterious impacts on health.

The origin of endocrine disruptors

Chris Metcalfe, professor emeritus in the environment school at Trent University, and his colleagues have identified several endocrine disruptors in the environment (water, soil, air, sediment), in food and consumer products. These include organochlorine pesticides, brominated flame retardants, per- and polyfluoroalkyl substances (used in non-stick coatings), alkylphenols (used in detergents), phthalates (used in cosmetics), bisphenol A and its analogues (used in plastics), organotins (used as anti-fouling agents) and others.

Bisphenol A (or BPA) is a good example of an endocrine disruptor. Since 1960, it has been incorporated into most of the plastics we use every day, from plastic bottles and food containers to cash register receipts and canned goods.

BPA has a structure that resembles natural estrogen. Because of this, it was considered for use as a medication to treat menopausal women in the 1930s, prior to its widespread use the production of plastics a few decades later.

In the body, BPA binds to estrogen receptors in cells and induces inappropriate and untimely responses, such as increasing cell proliferation, which could promote the development of tumours.

Infertility in animal species

A literature review led by Vicki Marlatt, an environmental toxicology researcher at Simon Fraser University, reveals a damning and widespread finding: many of these environmental contaminants impair reproduction in fish, amphibians, birds, mammals and humans, reducing their chances of producing viable offspring.

In humans and other animals, embryonic development and early life stages are the periods most susceptible to the effects of these contaminants.

Géraldine Delbès, a professor of reproductive toxicology at INRS, and her colleagues have shown that exposure to endocrine disruptors during this window of susceptibility leads to changes in testicular and ovarian programming.

For example, a decrease in androgens (testosterone and dihydrotestosterone) and an increase in estrogens can lead to a developmental disorder of the testes in children called testicular dysgenesis syndrome, which has increased globally in the past 50 years.

Fetal exposure can lead to adult disease

Our research with Cathy Vaillancourt, who studies pregnancy and toxicology at INRS, has shown that endocrine disruptors can interfere with the hormones produced by the placenta, known for its robust defence barriers, which can lead to health complications later in life. Chronic diseases such as diabetes and obesity have been associated with exposure to endocrine disruptors crossing the placental barrier during fetal development.

We also have shown that early exposure to endocrine modulators can affect the development of fetal mammary glands, and increase the risk of developing breast cancer in adulthood. These include BPA, brominated flame retardants and diethylstilbestrol (DES). Research by Étienne Audet-Walsh, who studies endocrinology and nephrology at Laval University, and his colleagues has suggested that exposure to endocrine disruptors could be linked to the development prostate cancer.

Some studies have found links between endocrine disruptors and the development of diabetes.

Multiple physiological effects

Endocrine disruptors can also alter other hormonal pathways, including those of the thyroid gland, which are also involved in stress control, immunity and metabolism.

With Caren Helbing, a biochemist at the University of Victoria, we have developed an understanding of the impacts altered thyroid hormone levels can have on other hormonal systems. For example, when endocrine disruptors decrease levels of thyroid hormones, reproduction, stress and metabolism are also affected.

Chris Martyniuk, an animal physiologist at the University of Florida, and his team have identified new targets of endocrine modulators, such as glucocorticoids (corticosteroids). They cite two examples of studies in their work, including the link between high levels of BPA in urine and an increased risk of cardiovascular disease. Certain endocrine disruptors (arsenic, phthalates, organophosphate pesticides) can interfere with insulin and lead to obesity.

From one generation to the next

Endocrine disruptors may also have transgenerational effects. For example, when fish are exposed to water contaminated with antidepressants, the offspring of their offspring show an altered stress response, even if that generations was never exposed to these chemicals.

Bernard Robaire, a professor of reproduction, pharmacology and toxicology at McGill University, has attempted to explain how endocrine disruptors affect future generations. The data he and his team have compiled indicates that the effects of these chemicals are not the result of changes in the genetic code, but other cellular changes, including which genes are turned on or off, a mechanism called epigenetics.

The long-term extent of these consequences is not completely understood. Additional genetic and epigenetic research on the mechanisms underlying the action of endocrine disruptors will be needed, but we also need a better understanding the roles of social, metabolic and environmental stressors.

Globally, we believe that international collaboration and leadership are increasingly needed to advance the science of endocrine disruptors. We must move from the stage of research that characterizes the negative health effects of these chemicals to one that develops best practices for their regulation, which remains an important topic of discussion around the world.

About a third of the food produced around the world goes to waste, and much of it ends up in landfills—where it becomes a source of methane, a greenhouse gas 25 times more potent than carbon dioxide. Eliminating waste is the ultimate solution, but some will always remain. For that there is a solution that nearly anyone can do: composting.Composting turns rotting garbage into a valuable soil enhancer that helps plants thrive. Farmers call it “black gold.” And whether you compost in your backyard or at a community facility, experts say it will reduce your trash and in a small way help fight climate change.“Don’t be afraid of it. It’s relatively easy. It’s not without its missteps but those are easily learned and corrected,” says Bob Rynk, lead author of The Composting Handbook and a professor emeritus at SUNY Cobleskill. What happens in a compost pile?Food turns into compost through the hard work of small microorganisms like bacteria, fungi, and protozoa. “When you have a compost pile, you become a microbe farmer. You’re managing microbes,” says Rhonda Sherman, a composting expert at North Carolina State University. “And what do microbes need? They need the same things we do. Which is air, water, food, shelter.”On a small scale, in your backyard or neighborhood, a compost pile should consist of three things: food scraps, water, and dry, woody material like yard trimmings or raked leaves.Yard trimmings are frequently referred to as “browns” and are high in carbon. Food scraps are called “greens” and are high in nitrogen. A compost pile should typically have twice as many browns as it does greens. Aside from preventing a pile from turning into a sloshy mess, browns are bulkier and create space for oxygen to move throughout the pile. That oxygen helps tiny microbes decompose food waste through a process called aerobic digestion. In landfills, deep piles of trash prevent oxygen from reaching decomposing food, and it’s instead broken down by microbes that can survive without air. The anaerobic digestion practiced by those microbes produces methane. In contrast, as aerobic microbes break down waste—”first, easier sugary compounds, and then proteins and fats, and then finally fiber,” says Rynk—they emit carbon dioxide, which is also a greenhouse gas, but less potent than methane.The microbes also give off heat, and in a large, well-managed pile, that heat can reach over 130 degrees Fahrenheit, enough to kill pathogens. The fresh compost left after several months is in a slower state of decomposition; it’s rich with microorganisms and nutrients such as nitrogen, phosphorus, and potassium. How to make a successful pileAt home, you should stir or mix the pile periodically and keep it damp. Both those steps will speed up the decomposition process. The stirring allows oxygen to reach all the nooks and crannies, and the dampness assures survival of the microorganisms, which need moisture to live.In fact, the most common reason backyard compost piles are unsuccessful is because they are too dry. But don’t drown the pile—adding more greens, which contain moisture, may be enough. If not, spraying water gently over the pile should do the trick.Wring out a wet sponge and observe its only slightly damp texture: “That’s what your compost pile should look like and feel like,” Sherman says. “You can see that it’s moist, but it’s not dripping all over.” Sherman says she urges people to maintain compost bins that are about three feet high so they can accumulate enough heat—but to keep them in the shade, where they won’t dry out.“People think they have to put it in the sun so it will heat up. That’s a myth! The action of the microorganisms heats up the materials in the bin,” she says.Not all food scraps are recommended for a backyard compost pile. The remains of fruits and vegetables are typically safe to toss in the pile, but uneaten meat or dairy are more likely to smell and attract pests. They also contain higher levels of fat, which take longer to break down. While it’s not uncommon to see rodents in a compost bin, turning the pile regularly prevents them from creating nests, and compost can effectively be made in enclosed bins. The Environmental Protection Agency has a more detailed list of items that shouldn’t be tossed in a compost pile. It includes items like yard trimmings treated with pesticides that might kill microorganisms. The food waste show here has been collected from residents of Lyon, France, and will be processed at a commercial composting facility. By adding food waste collection to regular recycling and trash collection programs, cities can reduce the overall amount of trash sent to landfills.Photograph by Nicolas Liponne, Hans Lucas/ReduxPlease be respectful of copyright. Unauthorized use is prohibited.Some communities are now offering food scrap bins alongside those for trash and recycling. Food scraps collected at the city level typically go to a large industrial composter where items are often shredded or chopped at arrival and processed at high temperatures. Composting at this level might be done in large piles or in silos. Because they send food waste to industrial compost facilities, municipalities tend to accept a wider variety of scraps than what you can throw in your backyard, and regulations vary by city. If you don’t have a backyard, access to a city-run food scrap service, or simply don’t want to mess with a compost pile, many urban gardens and farmers markets accept compost.And if you’re concerned about odor from keeping compost on your countertop or in your kitchen before moving it to a larger compost pile, Sherman says putting food scraps in the freezer is a “game changer.” By freezing your scraps, you hit pause on the decomposition process and prevent odors from forming. How do you compost with worms?  Composting with worms, or vermicomposting, produces an even more valuable soil enhancer. Worms digest scraps and excrete castings that are rich in plant nutrients. Researchers are also finding that the living microorganisms found especially in vermicompost can help protect crops from common diseases and reduce the need for herbicides and pesticides. Yet even though earthworms are sometimes found naturally at the bottom of a compost pile, they should not be added to a large, hot backyard compost bin. Earthworms don’t have lungs and instead breathe through their skin, which needs to remain moist to prevent them from drying out and dying. While a compost bin should be damp, it’s typically not moist enough for earthworms to survive. Instead, says Sherman, worms should be contained in smaller bins less than two feet high. Because they thrive in smaller spaces, earthworms can easily be contained in an enclosed bin under a kitchen sink or on an apartment balcony, making vermicomposting a potential option for people without backyards. The Natural Resources Defense Council has a tutorial here showing how to build a worm bin at home. What do you do with biodegradable/compostable food packaging?Products labeled “compostable” or “biodegradable,” such as packaging material or utensils, are becoming more popular, but are meant to be processed at an industrial composting facility. Ian Jacobson, the president of Eco-Products, a compostable product maker, says his company sold 200 products in 2010, but now offers more than 450. Compostable-labeled containers can be anything from paper and sugarcane-based bagasse to bioplastic, which is plastic made from plants like corn. Some, but not all are certified by the Biodegradable Products Institute (BPI), the largest certifier of compostables, which tests compostable products to ensure they can be processed at commercial facilities. Takeout food containers are often made of compostable paper. But if “you just toss the container in your compost bin, it’s just going to sit there,” says Sherman. Shredding the container into small pieces, no bigger than two inches, will give microbes a better chance at breaking it down. Even then, it may not break down easily. While a well-managed backyard compost pile can achieve high temperatures, the hotter temperatures at an industrial facility will break down material more effectively. Sherman also points out that compostable paper products like newspaper or paper towels can get “mushy” and compacted in a compost pile, preventing aeration.Food packaging made from bioplastics are not compostable in a home bin because they often have strong polymer bonds that can only be broken down in an industrial facility. However, not all bioplastics can be processed by commercial composters because some bioplastics contain toxic chemical additives to waterproof them or give them strength. (Learn more about bioplastics here.)How does composting help the environment? In 2018, the U.S. produced nearly 300 million tons of trash, about 4.9 pounds per person. After paper products, food was the second highest category of waste, comprising about 21 percent of what we throw away and increasing the size of landfills, the source of 34 percent of methane emissions.When done at a large scale, composting can make a dent in emissions. San Francisco, which established mandatory city-wide composting in 2009, has been able to divert 80 percent of its waste from landfills every year, more than 2.5 million tons overall.One estimate from the Natural Resources Defense Council finds that San Francisco’s composting laws reduced the equivalent of 90,000 metric tons of carbon dioxide every year, the same number of emissions as about 20,000 passenger vehicles.In addition to reducing landfill emissions, compost makes soil healthier. When layered on top of soil in a garden or on a farm, the organic matter found in compost improves unhealthy soils. It also helps bind soil particles together and holds more water. Better soil helps support plant growth, which can help sequester carbon from the atmosphere. Stronger, nutrient-rich soil also reduces the need for fertilizer and pesticides, which are pollutants themselves and are often produced with destructive mining practices and a high carbon footprint. In fact, the only downside to composting may be the “ick factor.” On that point, Sherman says not to worry. “It’s not stinky, it’s not gross. And once a week I go to my backyard compost bin. It takes me three minutes to compost. I just really try to encourage people. I try to tell people it’s so easy to do.”

A new exhibition ‘mingles the jolt of the dystopian with the lure of beauty’, writes Diane Cole.A strangely appealing sculpture – of a giant tree-like monument composed of swirling coils of black plastic, planted in a bed of bright green moss that creeps its way up to the structure’s tip, and peppered throughout with purplish-pink orchid blooms – has been luring passersby to stop in their tracks and peer through the store-front windows of the Weinberg/Newton Gallery in Chicago, Illinois. Many find themselves so engaged with the incongruous mix of the natural and the synthetic that, rather than walking on, they walk into the gallery itself to find out more, according to gallery director Nabiha Khan-Giordano. And when they do, they also recognise the familiar scent of fresh rain diffused into the air.

Human/Nature is an interactive, sensory-immersive exhibition currently on display at the non-profit gallery, and presented in partnership with the Bulletin of the Atomic Scientists, an organisation that identifies the impact of man-made threats on our world. It’s a show designed to connect, educate, and engage viewers with the urgent issues of climate change. Throughout, the show mingles the jolt of the dystopian with the lure of beauty – a primal reminder of what’s at stake that urges us forward to preserve what we have and, more than that, support and pursue actions that can help sustain us into the future. From that perspective, its purpose is not to shock us into action so much as to instil urgency and motivate us, asking: if we don’t act now, when will we?
Yet that question itself leads to another one: can art exhibits and projects stir action to help mitigate climate change? “Art can do what the scientists can’t do,” says Rachel Bronson, president and CEO of the Bulletin: make accessible, relatable, and understandable the abstract-sounding science of climate change. Rather than push us away from acting to mitigate the menacing future the studies warn we’re trending to, art can invite us to come closer, and help us envision a different future that we can also help shape.Monument by Regan Rosberg combines black plastic with moss and orchids to startling effect (Credit: Weinberg/Newton Gallery, Chicago, IL. Photography by Evan Jenkins)Monument, the show’s centrepiece, created by Denver-based artist Regan Rosberg, is only one example of how artists can translate abstract-seeming scientific research into striking works that connect us viscerally with the climate changes we’re grappling with. “You walk in and see the beautiful sod and the orchids, and you smell the aroma of the forest, and then you realise those swirling pieces are plastic, so ugly and so beautiful at the same time,” says Bronson.This quizzical kind of beauty is, in fact, part of Rosberg’s artistic strategy. “I try to hook people with beauty, first because it’s needed and second, it’s a way to engage people and keep them interested.” She additionally engages people with the rain scent she has created to diffuse through the gallery. “Scent is directly tied to memory,” she points out, and this particular scent is one that humans are particularly attuned to as part of our evolutionary make-up.
This scent that conjures both nature and memory helps evoke a sense of empathy, connection and wonder, she says. With their attention and their emotions thus captured, viewers then feel more comfortable delving deeper into the meanings behind the contradictions embedded in the piece. Rosberg explains that moss is a highly adaptive species that is 350 million years old. Orchids, too, are highly adaptive, its origins also dating back millions of years. They represent the many species that have evolved and survived over eons. “These are living things that can teach us to adapt and be resilient,” Rosberg says. But they are co-existing alongside this giant mass of plastic. “Often we use plastic for two seconds, but it can last for 1,000 years.”
Dual purpose
Enmeshing and entangling those materials together dramatises where we are now, she says: living in a world where dystopian fears can overwhelm our sense of hope, and paralyse our ability to act. Holding both the dystopian and hope at the same time can be scary, she acknowledges. What good art can do, though, is provide the perspective that allows us to recognise that resilience is possible and that we can act, and there are many ways to do so.
That is in fact one of the show’s main points, says its curator Cyndi Conn. “So much of the conversation now has the message that we’re beyond the point of saving. That’s the headline. But it’s not hopeless. We’re at a crossroads. The exhibit is very candid about how grave the situation is. But we also show the beauty and the resilience of the planet.”Karen Reimer uses textiles to create data visualisations showing the effects of climate change (Credit: Monique Meloche Gallery/Weinberg/Newton Gallery/ Photography: Evan Jenkins)Strolling from one gallery room to the next, visitors encounter one artwork after another posing this duality, each in its own way. There are colourful, comfy-looking textured quilts by Chicago-based artist Karen Reimer that incorporate into their designs small-scale maps and graphs charting the extending reach of climate change. Reimer calls these “data visualisations” that both map – and make it easier to grasp – the impact of climate change. “We can’t look at a list of numbers giving daily temperatures for 100 years and understand it without a lot of mental process effort,” she said at an artists’ panel sponsored by the gallery (and available online), “but we can look at a line graph and see that continual rise in temperature much more quickly and easily.” Embedding the information within shimmering textiles allows visitors to approach and begin to digest the reality that scientific research can make dauntingly abstract. 
Next up: delicate still-life watercolours by San Diego-based Laura Ball that depict entangled plants and animals engaged in – is it play, or is it an intricate dance of mutual destruction? Or perhaps their fight is based on adaptation as they evolve into an unknown future. “Most of the animals she incorporates are facing extinction. This is a reminder of the preciousness of biodiversity,” Conn says.Laura Bell’s watercolours show endangered animals in the form of a ‘mandala’, or sacred symbol (Credit: Weinberg/Newton Gallery/ Photography by Evan Jenkins)A continuous slide show presents powerful images taken by Donovan Quintero, a photojournalist for the Navajo Times (Diné bi Naaltsoos), documenting the dystopian-looking realities caused by drought, over-mining, wildfires and toxic waste dumps throughout the distressed lands of the Navajo Nation. The images seem surreal: the fire erupting like a distant volcano in the background of one photograph; then the mist of dust that enshrouds a riverbed; followed by a landscape of once-green land that is now a dried yellow-brown patchwork of cracks and creases. But the images depict reality, compelling us to confront how bias leads to a neglectful disregard that in turn amplifies the devastation of climate change on minority communities. Yet resilience resides in the images of the people who endure despite water shortages and lost grazing lands, and continue working to seek solutions.Donovan Quintero’s photos reveal the impacts of climate change on Navajo communities (Credit: Donovan Quintero/Weinberg/Newton Gallery)The show also includes an inventive array of reimaginings of the Doomsday Clock: the iconic symbol created by the Bulletin of the Atomic Scientists to alert humanity to our unceasing countdown to catastrophe, as gauged by the concurrent threats posed by nuclear weapons, climate change, disruptive technologies and Covid-19. Its current setting in its countdown to oblivion: 100 seconds from midnight.
As re-envisioned by the French collective Obvious working with the Russian photographer Stas Barnikas, the clock now tracks climate change. Super-imposed on the clock is a continuously changing video montage. It is an amalgam of Barnikas’s photographs documenting the changes already wrought on the remote landscapes of the Arctic, further transformed through an artificial intelligence algorithm devised by Obvious, to provide a glimpse of the future that is at once eerily beautiful and devastatingly empty.French art collective Obvious and Russian photographer Stas Barnikas have reimagined the Doomsday Clock (Credit: Weinberg/Newton Gallery/ Photography by Evan Jenkins)New York-based artist Matthew Ritchie has created a three-part piece collectively called “This world, this garden, this time, or never again (Proposal for a world garden, a living clock)”. It begins with an eye-catching blue-yellow-green-brown watercolour map of the globe viewed as if from space, with 12 anchor-like arrows pointing around its clock-like shape at each hour of the clock to a ballooned caption that has scribbled within a possible action that could turn a potential “doomsday clock” into the “life clock” of the title. (An example: One o’clock is “Increase carbon-neutral power generation to meet current needs of wind and solar.”)Matthew Ritchie’s version of the clock suggests collective actions that could be taken to tackle climate change (Credit: Weinberg/Newton Gallery/ Photography by Evan Jenkins)The second piece is a sober black-and-white vinyl version containing the same information, this time clearly and boldly printed and impossible to mix. The caption reads: “Unlike the doomsday clock, the goal of the ‘life clock’ is to build out collective action from the centre, moving simultaneously in all directions, with each proposal presented in response to a planetary boundary collapse.” Finally, the third piece is a blank clock that invites viewers to add post-it notes suggesting their own ideas and suggestions for fighting climate change; it is now almost entirely covered with messages in response.Rosberg’s Dear Future video features a range of ‘letters to the future’ (Credit: Weinberg/Newton Gallery/ Photography by Evan Jenkins)Rosberg similarly invites viewers to engage and respond to her video Dear Future, also included in the show. It is a narrated selection of the more than 150 letters from artists, activists, scientists, biologists, children and teachers, among others, that she has gathered, with each letter addressing the way climate change has affected their views of the future. Readings from the letters, that range from the hopeful to the poignant to the tragic, are interspersed with photos Rosberg took documenting the environmental changes she saw during her artist’s residency in the Arctic. At the show’s conclusion, viewers are invited to sit at a nearby desk and write, by hand, their own letters to the future. Those who write a letter receive a small vial containing the scent Rosberg created for Monument. So many people have contributed their thoughts, Rosberg has been asked to provide more scent as the show continues.
Before visitors leave the exhibition, they are given the chance to write to their elected representatives. They can also pause and learn from ongoing videos featuring a range of scientists and others presenting, on a more personal level, what they are doing. By all measures, the show is getting its message across. Attendance numbers rose so high that the exhibition was extended by a month, and the responses to individual artworks keep growing. And the show is sparking conversation among those who visit. “I’ve been present when people start talking about how climate change is personally affecting them,” Khan-Giordano says.But the realities facing us remain. “If we do nothing, we are in danger,” Bronson says. At the same time, she continues, “What we’re seeing on climate does give me optimism: you can see political parties globally responding… Even in the United States business community, you see a greater sense of urgency from 20 years ago… But we need to move faster.”
Can artists provide the inspiration for that push? “Art can be a punch in the gut,” says Conn. “But it does not have to be horrifying. It can also be inspiring. There is also a place for optimism. Because if we don’t have optimism, we won’t take action.”
Human/Nature is at the Weinberg/Newton Gallery in Chicago until 16 April.

Pick up the pieces: the battle to clean up Cornwall’s beaches Plastic pollution blights the Cornish coast, but local people are tackling the problemWhen eight-year-old Harriet Orme saw a dead hawksbill turtle in her Cornwall village’s harbour three years ago, the image haunted her. Not because the huge, critically endangered turtle had crossed the seas from the tropics to a defunct fishing harbour on the north coast of Cornwall, but because it had most probably died after ingesting thousands of tiny pieces of plastic.“Harriet is a womble,” her mother, Sophie Orme, says. “Now, wherever she goes, she automatically picks up litter and hands it to me.” The two are spending their morning, like countless mornings before, litter-picking on their nearest beach. In their home town of Portreath, with a population of around 1,400 permanent residents, environmental custodianship is catching on. “It’s becoming the culture of the whole village. From the village elders right down to the youngest kids. Even the local pub runs nightly beach cleans in the summer,” Orme says. The area’s social values, she believes, are changing, much like when smoking became taboo. “You become a pariah if you litter,” she says.Across Cornwall, community beach cleans have gathered momentum as a year-round activity appealing to all ages. Unlike surfing, dog-walking or cold-water swimming, beach cleans require little equipment or hardiness – just a common goal to keep treasured outdoor spaces litter-free.“Litter was always a part of my childhood in north Cornwall,” says 24-year-old Emily Stevenson. “We would build sandcastles out of plastic.” Although she and her father, Rob Stevenson, often carried out impromptu beach cleans, it was not until 2017 that they held their first community clean. But after a serendipitous moment made headlines – when Emily unearthed an empty packet of crisps from 1997, the same year she was born, it led to her wearing a graduation dress made from crisp packets that was widely reported – numbers of volunteers “exploded”. The duo formed the social enterprise Beach Guardian, and have since spent thousands of hours scouring various cliffs and coves in more than 200 beach cleans.Beach Guardian focuses its efforts on the seven bays between Newquay and Padstow, two of the county’s most well-trodden holiday destinations. This stretch of coastline is Rick Stein territory – the whimsical Cornwall of foraging in hedgerows, steaming mussels and stargazy pie – or at least as television would have you believe. But in the dead of winter, when country lanes are quiet and the long swathes of sand are no longer cluttered by windbreakers, beach towels and body boards, bands of locals come to the beach on the hunt for rubbish.On a winter morning around 50 people, armed with litter pickers and recycling sacks, have come out on a Sunday to offer a hand. Stormy weather and high spring tides have made rich pickings for them, as buried plastics, hidden for decades at the bottom of the sea bed, have churned up to the surface. Most volunteers crouch over tangles of seaweed, fishing plastic from burrows, but a small group leaves to remove a plastic pontoon wedged into a cliff before it breaks up into minuscule pieces of polystyrene.Around 5,000 items of marine plastic pollution exist for each mile of beach in the UK, according to the Marine Conservation Society. And, living in the county with the largest coastline (422 miles), it is no surprise that the Cornish are deeply invested in their surroundings. Fishermen’s kisses, nurdles and biobeads – special names for fragments of fishing nets and small plastic pellets – are part of the vernacular, recognised by locals as devastating to marine life. It can be an uphill battle when you realise the “unquantifiable” amount of microplastics in the ocean, Stevenson acknowledges. This doesn’t deter the most dedicated volunteers, who pass kitchen sieves over the sand, scouting for plastic flecks of colour.On the beach, a mother holds open a bag for her child, who runs back and forth, gleefully adding “juicy bits of plastic” to a bulging pile. “Once you start seeing it, you can’t not see it again,” Zoe Collis says. “By coming here you see the scale and complexity of the problem. It means when you go home you then start thinking, right, what do I not need? Do I need that plastic bottle of water? Probably not.”Beach cleans became a vital way for her family to integrate after they relocated from Staffordshire to Cornwall six years ago. “You start seeing the same faces. And you find out other things going on. It’s been a great way of finding a group of buddies and building a community,” she says. During the long days of the pandemic, regular cleans were a lifeline for families like hers. Especially at Christmas, as Omicron torpedoed festive plans, beach cleans provided a welcome escape. “We had hot chocolate and mince pies afterwards. It was something to do to get out of the house that felt safe,” Collis adds.After spending his childhood summers in north Cornwall and working on a nearby campsite as a student, Mark Pendlebury retired to the county late last year. At his first beach clean, he wants to give back to the beaches he has spent over five decades enjoying. Opening his palm, Pendlebury reveals four pieces of Lego, salvaged from a cargo spill. In 1997 more than 4.8m pieces of Lego bound for New York were lost at sea and are still washing up on Cornish beaches today. Among the pieces Pendlebury finds are a canary-yellow surfboard and a teal, thumb-sized figurine, which vaguely resembles an elephant, or perhaps a hippo. It’s tricky to tell as the bricks are slightly misshapen, their trademark bumps licked by waves until rounded. Such items are considered collectibles by avid beachcombers: the rare bits of junk that find their way to the shores from exotic places or decades past.“I have folders and folders of stuff that I refuse to give up,” says Emily Stevenson. “Each one tells you a story of a particular beach clean.” Her big thing is crisp packets. “I’ll remember this clean in 10 years’ time by this packet. Memories just seem to cling on to it.”Of course, front rooms and garden sheds can’t hold everything the cleaners find. Instead, Beach Guardian’s plastic bounty is used for educational purposes – as art activism. A statement from the group says: “Everything from our beach cleans is brought up to our Beach Guardian Lab. Volunteers sort through what we have. The large items like nets and rope are used for large art installations like our whale, giant puppets and our Plastic Age stone circle. The smaller items are used for school resources so that pupils can see first-hand what we are finding on our beach cleans and watch our Tune In Tuesday videos on YouTube.”Nets, ropes and large plastic items are shredded down and turned into kayaks to help recover more items at remote coves while other plastics are recycled into beach-cleaning stations. As a last resort, all waste in Cornwall is incinerated to generate electricity, so it’s very unlikely that anything will end up back in the ocean, the environment or in landfill.Beach Guardian is also pushing for policy change, starting with local authorities and businesses, through to politicians and multinational corporations. The team has met decision-makers from parliament and PepsiCo, to present the dangers of plastic in our ecosystem. Stevenson uses an analogy: “If you have a leaky sink in your bathroom, you wouldn’t spend year after year mopping up the floor; you’d fix the tap. Beach cleaning is mopping up the floor, but we’ll do that forever unless we turn off the plastic tap.”However, when the tourist season strikes, Cornwall tackles a very different litter crisis. Kevin Wood, who works in maintenance in Watergate Bay, is tasked with cleaning the beach every morning, mopping up the residue of picnics, barbecues and late-night beach parties.“​​It’s horrendous in the summer. We literally fill up black bags with barbecue rubbish, crisp packets, plastic spades, all sorts. When the bins are full, people just throw rubbish on the floor,” he says. According to Wood, fires cause some of the worst damage. Last year was particularly dire, with wooden chairs and tables stolen from the forecourt of a hotel used as fuel in the name of a good time. “I wish they could see it now when we’re picking mainly old stuff and fishing gear, so they could see the difference in the summer,” he says.One solution has been the rollout of individual beach-cleaning stations. The concept is amazingly simple – place a board, a litter picker and a bag at the entry point to each beach. In bright blue and yellow, the stations are hard to miss, serving as a constant reminder of environmental responsibility. The scheme, run by Cornish charity The 2 Minute Foundation, piloted in 2014 and now there are over 1,000 stations, one in every continent of the world.“The stations don’t discriminate. Lots of tourists will come along and take part, especially those who aren’t clued in about the organised beach cleans,” says Martin Dorey, the charity’s founder. He collaborates with tour operators that run summer beach cleans for holidaymakers, as well as artists selling jewellery and trinkets made from marine debris. “It appeals to people’s sense of giving back and feeling like they belong to the community by doing something positive,” Dorey says.Beach cleaners are encouraged to share photos under the hashtag 2minutebeachclean. After the first station was installed in Bude, Cornwall, Dorey measured a 68% drop in litter left on the beach that year. Fifteen years later, with hashtags registered as far as Antarctica, the scale of the charity’s work is harder to track. “It’s the key that unlocks laziness. Two minutes is nothing; everybody’s got two minutes,” says Dorey. By setting an achievable goal people are inspired to make incremental changes. “We don’t need 100 perfect people – we need everybody to be imperfect, but at least trying,” he adds.For Dorey, beach cleaning offered respite after a difficult divorce. But he has also heard testimonies from others who have used the ritual to silence anxious or even suicidal thoughts. Now, The 2 Minute Foundation has an employee trained as a mental-health first aider, in the hope of spotting signs of struggle early on.The benefits of beach cleaning on mental health are still relatively anecdotal, although recognition of nature’s restorative qualities is becoming more mainstream. In lockdown, savouring time spent in open spaces became a crutch for many of us, to such an extent that in July 2020, the Environment Secretary dedicated £4m to “green social prescribing”. GPs and other healthcare practitioners can refer patients with mental health concerns to nature-based activities, such as local walking schemes and community gardening projects.This opens the door to exploring our relationship to aquatic environments, ponds, lakes, rivers and oceans. At the forefront is BlueHealth, a pan-European research project led by a University of Exeter department based in Truro. In a 2019 study, experts found that people living less than 1km from the UK coast had “significantly lower” odds of being at a high risk of “common mental disorders”, such as anxiety or depression, compared to those living further than 50km away. The link was stronger within socioeconomically deprived communities, indicating that access to blue spaces could reduce health inequalities.“The doctors of yesteryear had the right idea when they would prescribe the coastline as a type of medicine,” says Jolyon Sharpe, a countryside officer at Cornwall Council. “Beach cleaning can be done beautifully in isolation; it can be very therapeutic, almost meditative,” says Sharpe. The melange of sounds – crashing waves, blustering wind and seagulls crooning – is pivotal. “Everything you hear is a sensory overload, and that’s incredibly good for your mental wellbeing.” And, when you add an altruistic element, such as cleaning, the satisfaction is twofold.“One thing that brings everyone together is that the coastline of Cornwall is beautiful,” says Sharpe. “The key thing is the beach is for everyone to enjoy, but we’ve got to protect it. Litter picking is one really simple way that everybody can give back to the environment that they love.”TopicsPollutionThe ObserverPlasticsCornwallCornwall holidaysfeaturesReuse this content
