Microplastics have been found across all of Earth's depths and altitudes, from plastic debris in the Mariana Trench to fragments found in snow samples near the summit of Mount Everest.

Microplastics have been found everywhere there is liquid or vapor water, from the oceans and tropical waters to polar ice and the air we breathe, posing growing risks to wildlife and ecosystems.

Research shows that over 1,000 metric tons of microplastics fall on national parks every year—equivalent to 120 million bottles of water.

Microplastics have been identified across human body systems, with research finding they are most commonly ingested through inhalation, drinking water, and diet before crossing barriers into organs.

The prevalence of microplastics came from plastic’s affordability and versatility

Microplastics' durability and overuse have led to massive pollution that overwhelms the planet's ecosystems. Avian, terrestrial, and marine life have been observed to contain microplastics in their bodies, but reverting to paper, cotton, and other materials in manufacturing also brings environmental challenges.

From soil to beer, microplastic pollution is all around us

Marine plastic pollution has been studied for decades, but the extent and effects of plastic pollution elsewhere is only just beginning to be explored.

Microplastics are infiltrating the human body with unclear but concerning effects

Scientists have linked microplastics to immune system damage, hormone disruption, inflammatory diseases, and even cancer—yet most of their health impacts remain unknown due to limited research. Studies suggest we ingest about a credit card's worth of plastic weekly.

Microplastics 101: What we know about the contaminants invading our bodies

Fifty-one trillion particles of microplastics float in our oceans. Yet there is very little science of how this affects our health. This quick 2-minute video explains the dangers of microplastics.

Research suggests microplastics disrupt photosynthesis in plants and algae, and this damage in crops may already rival the impact of climate change on food supplies.

Microplastics are entering human food chains through carrots, wheat, and other foodstuffs grown in farmlands fertilized by sewage sludge.

Research shows that microplastics and nanoplastics can accumulate in major arteries, and patients with these deposits are significantly more likely to suffer heart attacks, strokes, or death.

Airborne microplastics may influence cloud formation and climate

Microplastics are increasingly found in the atmosphere and may affect the climate by reflecting or absorbing sunlight based on their pigmentation. Like mineral dust, they may become cloud seeders and alter regional precipitation patterns as they become more abundant.

Synthetic textiles and tires account for more than 60% of ocean microplastic pollution, which enters the seas via runoff and wastewater discharge.

As of 2025, the FDA states that microplastics have not yet been shown to pose a risk to human health, though it acknowledges that evidence suggests microplastics and nanoplastics have entered the food supply.

The challenges of trying to study microplastics in microplastic-abundant labs

The presence of microplastics in instruments, surfaces, and air has made accurate measurement of their levels in lab samples difficult, given the high likelihood of contamination. While the use of stainless steel tools in a sealed, clean lab may reduce accidental exposure, existing methods can misidentify biological substances, such as fat, as plastics, further complicating research.

Scientists have found that sewage sludge used as fertilizer introduces various microplastics into soil, which persist in farmland for decades.

After swallowing 23 pieces of plastic, seabirds experience a 90% death rate

Researchers found that this threshold is also met when marine mammals ingest 29 pieces and when sea turtles consume approximately 405 pieces. Almost half of the sea turtles, a third of the seabirds, and one in ten of the marine mammals studied had eaten plastic.

Mermaid tears are a long-lasting and hazardous form of ocean microplastic pollution, whose chemical composition enables them to contain higher concentrations of certain toxins than the surrounding environment.

Explore the UN’s interactive guide to global plastic pollution

Around the world, 1 million plastic drinking bottles are purchased every minute, while 500 billion single-use plastic bags are used worldwide every year. In total, half of all plastic produced is designed to be used only once—and then thrown away.

Using AI to track plastic pollution in real time

Explore Global Plastic Watch, the first-ever, near-real-time, high-resolution map of plastic pollution. Global Plastic Watch uses advanced satellite data technology and machine learning to measure piles of plastic waste from space.

During wash cycles, synthetic fabrics shed millions of plastic microfibers, making them a significant source of global microfiber pollution.

What to do about the microplastics in your laundry

Synthetic fabrics shed millions of tons of microplastics into oceans each year, largely through laundry wastewater. Here are ways to reduce the pollution.

Most plastics are not biodegradable because breaking their chemical bonds requires temperatures lethal to most microbes, and these organisms have not been exposed to plastic long enough to evolve the necessary enzymes.

The global plastic crisis in images

For decades we have relied on plastics to keep us safe, insulate our homes, and make sure our food stays fresh. But when does plastic’s life come to an end?

When diving and snorkeling in environments containing reefs, avoid touching reefs, anchoring on them, or using sunscreen with active ingredients harmful to marine life.

The amount of plastic chemicals in 300 everyday Bay Area foods

Food production is more complicated than it appears, and manufacturing, packaging, and shipping processes can add significant substances to your food. This massive project compiled data on 300 samples of foods delivered to the San Francisco area, testing for the presence of 18 different kind of plastic. Learn how to read the data here with its helpful guides and then explore the table yourself.

Forever chemicals accumulate up the food web, with recent research indicating that apex predators have higher concentrations because they're eating prey that also have accumulated the substances.

Nanoplastics can bypass the blood-brain barrier and may harm the nervous system

Nanoplastics are formed from the breakdown of microplastics and can breach cells. Their large surface area relative to size allows them to carry higher concentrations of forever chemicals than the surrounding environment into sensitive organs.

How existing technology could prevent nearly 80% of plastic pollution

More than 28 million tons of plastic enters the environment each year, where it harms animals and damages habitats. A study co-authored by researchers at The Pew Charitable Trusts found that this flow can be reduced by nearly 80% in the next 20 years using existing waste management and recycling technology.

Some algae have helped remove microplastics from water after being bioengineered to clump together with these contaminants, forming an easily collectible microplastic-algae sludge.

Visualizing the enormity of plastic waste compared to global landmarks

The team at Reuters Graphics visualizes the world’s addiction to plastic bottles. Around the world, almost 1 million plastic bottles are purchased every minute. The illustrations included in this visual explainer show what that pile of plastic would look like if it was collected over longer periods of time and how large the piles would be compared to famous landmarks.

A remote Scottish island is awash in forever chemicals even though there are no obvious industrial sources nearby, and scientists suspect the toxic substances are accumulating via seaspray.

Plastic debris across the ocean aids the spread of invasive species

The durable, long-lasting material can serve as a platform for living organisms to latch onto and ride over vast distances. After the 2011 earthquake and tsunami in Japan, a large dock carrying 100 tons of living organisms native to Japan washed up on Oregon's coastline, confirming the ecological threat.
