Editor’s note: In the short span of time that plastic was invented, plastic has become ubiquitous. Not just in its widespread use in our daily lives but also in the pervasive form that it has entered our ecosystem and our bodies. In its nanoparticle (any particle of diameter ranging from 1 to 100 nanometer) form, plastics are capable of entering our bodies more so than a coarse particle of plastic is. The following article explains the direness of the situation.
The air is plasticized, and we are no better protected from it outdoors than indoors. Minuscule plastic fibers, fragments, foam, and films are shed from plastic stuff and are perpetually floating into and free-falling down on us from the atmosphere. Rain flushes micro- and nanoplastics out of the sky back to Earth. Plastic-filled snow is accumulating in urban areas like Bremen, Germany, and remote regions like the Arctic and Swiss Alps.
Wind and storms carry particles shed from plastic items and debris through the air for dozens, even hundreds, of miles before depositing them back on Earth. Dongguan, Paris, London, and other metropolises around the world are enveloped in air that is perpetually permeated by tiny plastic particles small enough to lodge themselves in human lungs.
Toxic Tires
Urban regions are especially full of what scientists believe is one of the most hazardous particulate pollution varieties: synthetic tires’ debris. As a result of the normal friction caused by brake pads and asphalt roads, and of weathering and wear, these tires shed plastic fragments, metals, and other toxic materials. Like the plastic used to manufacture consumer items and packaging, synthetic tires contain a manufacturer’s proprietary blend of poisons meant to improve a plastic product’s appearance and performance.
Tire particles from the billions of cars, trucks, bikes, tractors, and other vehicles moving across the world escape into air, soil, and water bodies. Scientists are just beginning to understand the grave danger: In 2020, researchers in Washington State determined that the presence of 6PPD-quinone, a byproduct of rubber-stabilizing chemical 6PPD, was playing a major factor in a mysterious long-term die-off of coho salmon in the U.S. Pacific Northwest. When Washington’s fall rains heralded spawning salmon’s return from sea to stream, the precipitation also washed car tire fragments and other plastic particles into these freshwater ecosystems.
Up to 90 percent of all coho salmon returning to spawn in this region have died—much greater than is considered natural. As the study’s lead author, environmental chemist Zhenyu Tian, explained in a 2020 interview with Oregon Public Broadcasting, 6PPD-quinone appears to be a key culprit: “You put this chemical, this transformation product, into a fish tank, and coho die… really fast.”
Microplastic Inside Human Airways
While other researchers had previously searched for, and detected, microplastic dispersed in indoor and outdoor air, Alvise Vianello, an Italian scientist and associate professor at Aalborg University in Denmark, was the first to do so using a mannequin emulating human breathing via a mechanical lung system, publishing his study’s results in 2019. (Despite the evidence his research provides—that plastic is getting inside of human bodies and could be harming us—it was not until 2022 that modern health researchers first confirmed the presence of microplastics in human lungs. And as comprehensive health research has ramped up, we are just beginning to understand how having plastic particles around us and in us at all times might be affecting human health.)
Vianello and his colleague Jes Vollertsen, a professor of environmental studies at Aalborg University, explained that they’ve brought their findings to researchers at their university’s hospital for future collaborative research, perhaps searching for plastic inside human cadavers. “We now have enough evidence that we should start looking for microplastic inside human airways,” Vollertsen said. “Until then, it’s unclear whether or not we should be worried that we are breathing in plastic.”
When I met Vollertsen in 2019, he had speculated that some of the microplastic we breathe in could be expelled when we exhale. Yet even if that’s true, our lungs are indeed holding onto some of the plastic that enters, potentially resulting in damage.
Other researchers, like Joana Correia Prata, DVM, PhD, who studied microplastics at the University of Aveiro in Portugal, have highlighted the need for systematic research on the human health effects of breathing in microplastic. “[Microplastic] particles and fibers, depending on their density, size, and shape, can reach the deep lung causing chronic inflammation,” she said. Prata noted that people working in environments with high levels of airborne microplastics, such as those employed in the textile industry, often suffer respiratory problems. The perpetual presence of a comparatively lower amount of microplastics in our homes has not yet been linked to specific ailments.
While they’ve dissected the bodies of countless nonhuman animals since the 1970s, scientists only began exploring human tissues for signs of nano- and microplastic in earnest during the late 2010s and early 2020s. This, despite strong evidence suggesting plastic particles—and the toxins that adhere to them—permeate our environment and are widespread in our diets. From 2010 to 2020, scientists have detected microplastic in the bodies of fish and shellfish; in packaged meats, processed foods, beer, sea salt, soft drinks, tap water, and bottled water. There are tiny plastic particles embedded in conventionally grown fruits and vegetables sold in supermarkets and food stalls.
Petrochemical-Based Plastics, Fertilizers, and Pesticides
As the world rapidly ramped up its production of plastic in the 1950s and ’60s, two other booms occurred simultaneously: that of the world’s human population and the continued development of industrial agriculture. The latter would feed the former and was made possible thanks to the development of petrochemical-based plastics, fertilizers, and pesticides.
By the late 1950s, farmers struggling to keep up with feeding the world’s growing population welcomed new research papers and bulletins published by agricultural scientists extolling the benefits of using plastic, specifically dark-colored, low-density polyethylene sheets, to boost the yields of growing crops.
Scientists laid out step-by-step instructions on how the plastic sheets should be rolled out over crops to retain water, reducing the need for irrigation, and to control weeds and insects, which couldn’t as easily penetrate plastic-wrapped soil.
This “plasticulture” has become a standard farming practice, transforming the soils humans have long sown from something familiar to something unknown. Crops grown with plastic seem to offer higher yields in the short term, while in the long term, use of plastic in agriculture could create toxic soils that repel water instead of absorbing it, a potentially catastrophic problem. This presence of plastic particles in the soil causes increased erosion and dust—as well as the dissolution of ancient symbiotic relationships between soil microbes, insects, and fungi that help keep plants—and our planet—alive.
From the polluted soils we’ve created, plants pull in tiny nanoplastic particles through their roots along with the water they need to survive, with serious consequences: An accumulation of nanoplastic particles in a plant’s roots diminishes its ability to absorb water, impairing growth and development. Scientists have also found evidence that nanoplastic may alter a plant’s genetic makeup in a manner increasing its disease susceptibility.
In a 2022 study, researchers showed that nanoplastics less than 100 nanometers wide can enter the blood and organs of animals and cause inflammation, toxicity, and changes in neurological function.
Clearly, micro- and nanoplastics are getting into us, with at least some escaping through our digestive tracts. We seem to be drinking, eating, and breathing it in.
And these tiny particles are just one component of plastic’s myriad forms of pollution. From the moment plastic’s fossil fuel ingredients are extracted, to its production, transportation, use, and eventual disposal in landfills, incinerators, and the environment, the plastics pipeline emits toxic chemicals that pollute Earth’s air, soils, waters, seas, animals, plants, and human bodies, and releases greenhouse gases that drive the climate crisis. Most often harmed are already underserved groups, including Black, Brown, Indigenous, rural, poor, and fenceline communities everywhere, driving severe injustice worldwide.

Decision Follows Lawsuit, Permit Suspension, Public Pressure
WASHINGTON— The U.S. Army Corps of Engineers announced Wednesday it will require a full “environmental impact statement” for the massive petrochemical complex Formosa Plastics proposes to build in St. James Parish, Louisiana. The decision is a major victory for opponents of the plant, who sued to block the project in January 2020 and convinced the Army Corps to suspend its permit last fall.
Wednesday’s announcement means the Army Corps will now do a complete analysis of the public health, environmental, climate, environmental justice and cultural impacts of what would be one of the world’s biggest plastic-making plants. Plaintiff groups representing the Black and low-income communities affected by the project — from an already polluted industrial corridor known as Cancer Alley or Death Alley — have long said a proper environmental review would show the project should never be built.
“The Army Corps has finally heard our pleas and understands our pain. With God’s help, Formosa Plastics will soon pull out of our community,” said Sharon Lavigne with RISE St. James, who earlier this year was awarded the Goldman Environmental Prize for her work defending her community from petrochemical polluters. “Nobody took it upon themselves to speak for St. James Parish until we started working to stop Formosa Plastics. Now the world is watching this important victory for environmental justice.”
RISE St. James, Louisiana Bucket Brigade and Healthy Gulf were represented in the litigation over this permit by the Center for Biological Diversity. Local opponents of the project have been aggressively dismissed, arrested and publicly criticized over their work to stop this project, which received huge taxpayer subsidies from the state.
“Today’s announcement is the ultimate David v. Goliath victory,” said Anne Rolfes, executive director of Louisiana Bucket Brigade. “We were not scared of Formosa Plastics and its $9 billion project, or the fact that our governor has been cheering for Formosa all along. St. James Parish residents are the ones who have shown leadership and wisdom. What the Corps has done today is common sense. Of course one of the biggest plastics plants in the world should require an environmental impact statement. Our state and federal officials should have demanded it from the outset. I am hopeful that this is the nail in the coffin of Formosa Plastics in St. James Parish. And don’t try to build somewhere else. Pack up and go home.”
The proposed facility would emit 13.6 million metric tons of greenhouse gases each year, the equivalent of 3.5 coal-fired power plants. It will also produce 800 tons of toxic air pollutants annually, doubling air emissions in St. James Parish, to produce plastic for single-use packaging and other products. Recent studies have linked exposure to air pollution with higher COVID-19 death rates. It’s one likely factor in the disease’s disproportionate impact on Black Americans.
The lawsuit sought to invalidate Clean Water Act permits issued by the Army Corps in 2019. It asserted that officials violated federal laws in approving the destruction and damage of wetlands, which help protect the region from hurricanes that are intensifying with climate change. The Corps also ignored the water, air, climate, and health impacts of the complex and failed to properly evaluate and protect burial sites of enslaved people discovered on the property.
“This long-overdue review will show the unacceptable harm Formosa Plastics’ massive petrochemical complex would inflict on this community, our waterways, and our climate,” said Julie Teel Simmonds, a senior attorney at the Center. “This terrible project shouldn’t have been rubber-stamped and it should never be built. Climate action and environmental justice mean we have to stop sacrificing communities and a healthy environment just to make throwaway plastic.”
The growing chorus of project opponents includes the United Nations Office of the High Commissioner on Human Rights, which called the project “environmental racism” in March and urged U.S. officials to reject the project.
Formosa Plastics’ massive proposed petrochemical complex would include 10 chemical manufacturing plants and numerous support facilities, spanning 2,500 acres, just one mile from an elementary school. By turning fracked gas into the building blocks for a massive amount of single-use packaging and other wasteful plastic products, the project would worsen climate change and the ocean plastic pollution crisis.
Last year Formosa Plastics agreed to pay a record $50 million in cleanup and restoration costs to settle a civil lawsuit after its Point Comfort plant discharged billions of plastic pellets into Texas waterways over many years. That settlement included a commitment to zero future plastic discharges from the Texas plant — a standard that has not been applied to its plant in Louisiana.
The Center for Biological Diversity is a national, nonprofit conservation organization with more than 1.7 million members and online activists dedicated to the protection of endangered species and wild places.
RISE St. James is a faith-based organization working to protect the land, air, water and health of the people of St. James Parish from the petrochemical industry.
The Louisiana Bucket Brigade collaborates with communities adjacent to petrochemical plants, using grassroots action to create an informed, healthy society and hasten the transition from fossil fuels.
Healthy Gulf is a regional nonprofit whose purpose is to collaborate with and serve communities who love the Gulf of Mexico by providing the research, communications, and coalition-building tools needed to reverse the long pattern of over exploitation of the Gulf’s natural resources.
A new study has found microplastics present inside human placentas, which could potentially affect fetal health and development.
The microplastics probably entered the women’s bodies through ingestion and inhalation, and then translocated to the placentas, the study suggests.
While further research needs to be done on the subject, it is believed that these microplastics could disrupt immunity mechanisms in babies.
Plastic is everywhere — literally everywhere. A growing body of research shows that plastic is not only filling the world’s oceans and wilderness regions, it’s also invading our bodies through the air we breathe, the water we drink and the food we consume. And now, a new study has shown that microplastics — tiny plastic particles smaller than 5 millimeters but bigger than 1 micron — are even present inside human placentas, posing a potential risk to fetal health and development.
Published this month in Environmental International, the study examined six human placentas from women who experienced healthy pregnancies and births. During delivery, the obstetricians and midwives followed a “plastic-free protocol,” swapping plastic gloves for cotton ones, and not using any plastic equipment or supplies to avoid cross-contamination.
The researchers found a total of 12 microplastic fragments in four of the six placentas. Three of these pieces were recognized as polypropylene, a plastic commonly used in food containers and packaging. While the other pieces were harder to identify, they appeared to be plastic bits from “man-made coatings, paints, adhesives, plasters, finger paints, polymers and cosmetics and personal care products,” according to the study.
The effects of microplastics in the human body on health are still largely unknown, but the researchers said it was “a matter of great concern” due to the critical role the placenta plays in fetal development.
Lead author Antonio Ragusa, director of obstetrics and gynecology at the San Giovanni Calibita Fatebenefratelli hospital in Rome, said it’s likely that microplastics would be present in the babies themselves, although further research would need to confirm this.
“I cannot support it with scientific evidence, since ours is the first study in the world on this topic, [but] I think that if we could look for them we will also find microplastics in the organs of the newborn, because the placenta is a temporary fetal organ, and not a maternal organ,” Ragusa told Mongabay in an emailed statement. “Of course this is just a guess.”
While all of the babies were healthy at birth, Ragusa said that the microplastics in the placenta had the potential to “alter several cellular regulating pathways … such as immunity mechanisms.”
“The presence of MPs [microplastics] in the placenta tissue requires the reconsideration of the immunological mechanism of self-tolerance, a mechanism that may be perturbed by the presence of MPs,” Ragusa said. “In fact, it is reported that, once present in the human body, MPs may accumulate and exert localized toxicity by inducing and/or enhancing immune responses and, hence, potentially reducing the defense mechanisms against pathogens and altering the utilization of energy stores.”
The researchers say it’s likely that the microplastics entered the mothers’ bodies through food ingestion or through respiration, and then translocated into the placentas.
Steve Allen, a microplastics researcher from the University of Strathclyde in Glasgow, who was not involved in the study, said he wasn’t surprised by the findings: “I’d say with complete confidence that using the right tools, we will find it in every part of the human body.”
A similar study has shown that pregnant rats forced to inhale nanoplastics ended up having particles present in their placentas, as well as the fetal liver, lungs, heart, kidney and brain.
“Considering it can move through rats like that, I wouldn’t be surprised if it can do exactly the same thing to humans,” said Deonie Allen, also a microplastics researcher at the University of Strathclyde.
Ragusa says he and his colleagues will be doing further research on microplastics with regard to maternal and infant health.
“We now have to understand if microplastics are present in the newborn at birth and we will do it by taking the umbilical cord blood at birth,” he said. “Another important step will be to understand if microplastics are present in breast milk.”

Indigenous teachings are thousands of years old. People born into these traditions are raised into knowledge that those born outside do not—and should not—have. Do not steal from others traditions. Instead, research your own family history and connect to your own roots.
This award-winning documentary deals with the popularization and commercialization of Native American spiritual traditions by Non-Indians.
Important questions are asked of those seeking to commercially exploit Tribal rituals and copy sacred ceremonies and those vested with safeguarding sacred ways. The film represents a wide range of voices from Native communities, and speaks to issues of cultural appropriation with humour, righteous anger, and thoughtful insight.

Our use of plastics has threatened oceans and the marine biodiversity. But our efforts for plastic cleanup, may well threaten a less-known marine ecosystem. This article was originally published in DW.com
Little is known about the neuston, but marine biologists fear this community of organisms living on the ocean surface could be decimated as nets sweep up plastic pollution.
In May 2017, shells started washing up along the Ligurian coast in Italy. They were small and purple and belonged to a snail called Janthina pallida that is rarely seen on land. But the snails kept coming — so many that entire stretches of the beach turned pastel.
An unusual wind pattern had beached the animals. And for the people who walked the shore, this offered a rare encounter with a wondrous ecosystem that most of us have never heard about: The neuston.
The neuston, from the Greek word for swimming, refers to a group of animals, plants and microorganisms that spend all or large parts of their life floating in the top few centimeters of the ocean.
It’s a mysterious world that even experts still know little about. But recently, it has been the source of tensions between a project trying to clean up the sea by skimming plastic trash off its surface, and marine biologists who say this could destroy the neuston.
A world between worlds
The neuston comprises a multitude of weird and wonderful creatures. Many, like the Portuguese man-of-war, which paralyzes its prey with venomous tentacles up to 30 meters long, are colored an electric shade of blue, possibly to protect themselves against the sun’s UV rays, or as camouflages against predators.
There are also by-the-wind sailors, flattish creatures that raise chitin shields from the water like sails; slugs known as sea dragons that cling to the water’s surface from below with webbed appendages; barnacles that build bubble rafts as big as dinner plates; and the world’s only marine insects, a relation of the pond skater.
Between the Worlds
They live “between the worlds” of the sea and sky, as Federico Betti, a marine biologist at the University of Genoa, puts it. From below, predators lurk. From above, the sun burns. Winds and waves toss them about. Depending on the weather, their environment may be warm or cool, salty or less so.
But now, they face another — manmade — threat from nets designed to catch trash. A project called The Ocean Cleanup, run by Dutch inventor Boyan Slat, has raised millions of dollars in donations and sponsorship to deploy long barriers with nets that will drift across the ocean in open loops to sweep up floating garbage.
Plastic and marine life are moved by currents
“Plastic could outweigh fish in the oceans by 2050. To us, that future is unacceptable,” The Ocean Cleanup declares on its website. But Rebecca Helm, a marine biologist at the University of North Carolina Asheville, and one of the few scientists to study this ecosystem, fears that The Ocean Cleanup’s proposal to remove 90% of the plastic trash from the water could also virtually wipe out the neuston.
One focus of Helm’s studies is where these organisms congregate. “There are places that are very, very concentrated and areas of little concentration, and we’re trying to figure out why,” says Helm. One factor is that the neuston floats with ocean currents, and Helm worries that it might collect in the exact same spots as marine plastic pollution. “Our initial data show that regions with high concentrations of plastic are also regions with high concentrations of life.”
The Ocean Cleanup says Helm’s concerns are based on “misguided assumptions.”
“It’s true that neustonic organisms will be trapped in the barriers,” says Gerhard Herndl, professor of Aquatic Biology at the University of Vienna and one of project’s scientific advisors. “But these organisms have dangerous lives. They’re adapted to high losses because they get washed ashore in storms and they have high reproductive rates. If they didn’t, they’d already be extinct.”
Helm says they just don’t know how quickly these creatures reproduce, and in any case recovering from passing storm is very different from surviving The Ocean Clean Up’s systems which could be in place for years.
Still a lot to learn about the neuston
In December, The Ocean Cleanup and Helm participated in a symposium on the topic hosted by the Institute for Risk and Uncertainty at the University of Liverpool in the UK. Since then, direct communication between them has stopped, says Helm. “They’re not interested in talking to me anymore.”
Both sides agree that much is still unknown about the neuston. But one thing that has been established is that most of the oceans’ fish spend part of their lifecycle in the neuston. “More than 90% of marine fish species produce floating eggs that persist on the surface until hatching,” Betti says.
The Ocean Cleanup has undertaken one of the few studies into this ecosystem, collecting data on the neuston on the relative abundance of neuston and floating plastic debris in the eastern North Pacific Ocean during a 2019 expedition to the Pacific Garbage Patch, an area where plastic pollution has accumulated on a vast scale. But it is not yet sharing what it has found. The information was being prepared for publication in an as of yet unspecified journal, probably some time next year, an Ocean Cleanup spokesperson said.
Is the solution inshore?
Helm believes the best way to tackle the marine plastic problem would be to position the barriers closer to land — across river mouths and bays — to catch garbage before it reaches the sea.
“Stopping the flow of plastic into the ocean is the most cost-effective — and literally effective — way to ensure that it’s not entering our environment,” she says. As for the plastic already floating in open waters, she does not believe it is worth sacrificing parts of neuston and wants to see more research first.
The Ocean Cleanup has made barriers across rivers a part of its mission. But it is also going ahead with its original vision of pulling trash from the open water. In late 2018, the project deployed a 600-meter, u-shaped prototype net into the Great Pacific Garbage Patch.
The system ran into difficulties, failing to retain plastic as hoped, and needing to be brought shore for repairs and a design upgrade, after which Ocean Cleanup says it gathered haul of plastic that it will recycle and resell to help fund future operations. Over the next two years, the project hopes to deploy up to 60 such barriers to collect drifting flotsam. Helm isn’t the only one concerned about these plans.
“We should think twice about every action we take in the sea,” Betti says. “In nature, nothing is as easy as we think, and often, we’ve done a lot of damage while trying to do a good thing.”
