Microplastics accumulate up the food chain, increasing in concentration in predators compared with prey.
An examination of McDonald's water under a microscope revealed a microfiber and another unidentified black object.
The shock findings emerged after scientists studied the impact of pollution in the West Pacific Kuril-Kamchatka Trench in the Pacific Ocean.
"These are opportunities to learn what we can do to better protect whales, we don't have many opportunities to see and learn about orcas off the Oregon coast."
Chinese scientists have developed a small, self-propelled robot that can "swim" into the oceans' hard-to-reach spots and clean them up.
Viruses that cause sickness in humans can attach to microplastics, remaining infectious for much longer than they would otherwise.
Microplastics consist of tiny pollutants that often elude detection, but scientists recently found the pollutants can be snatched from the air by spiderwebs.
Nigerian drinking water is massively affected by microplastics, according to new research.
Scientists found that microplastics are being transported thousands of miles all over the world by ocean air, snow, sea spray, and fog.
The tiny plastic particles have been found everywhere from the highest peaks to the bottom of the ocean—and we still don't know their health implications.
Tiny plastic fragments have been documented in virtually every ecosystem on Earth.
Microplastic pollution is ubiquitous, but the processes that distribute the particles between marine, terrestrial and atmospheric environments around the planet remain poorly understood.
Microplastics are ubiquitous in the marine environment. However, accurately classifying and quantifying them in the oceans has proven challenging for researchers.
"We keep putting millions of tonnes of plastic into the ocean every year. This research shows that it is not going to stay there forever. The ocean is giving it back to us," said researcher Steve Allen.
"It was very surprising to find microplastics so deep," researcher Winnie Courtene-Jones told Newsweek.
An international team of researchers describeD how deep-sea currents transport and dump large quantities of microplastic across the ocean floor.
"We have new species turning up that are already contaminated and so we have missed the window to understand these species in a natural environment," said marine ecologists Alan Jamieson.
The Ohio House of Representatives has passed a bill that would prohibit municipalities from restricting the use of plastic bags.
The new estimate based on samples collected in California 8.3 million per cubic meter—not ten as previously calculated.
"We were shocked to see the high number of plastic particles released into the beverage," a co-author of the study told Newsweek.
The director said deep sea research is "shamefully underfunded" and called for a "global fleet of swarm robotics" to study Earth's oceans.
Plastic fragments are frequently ingested by a wide range of marine animals that often mistake the substance for food.
"It's highly likely that any pollution that impacts the health of soil fauna, such as earthworms, may have cascading effects on other aspects of the soil ecosystem, such as plant growth," researcher Connor Russell said.
Scientists studied the feces of people from around the world.
The masses of plastic could starve deep-sea ecosystems and hard animals, scientists fear.
The study "highlights the magnitude of plastic pollution," a professor of conservation told Newsweek.
Starfish from the 1970s were found to have similar levels of microplastics as those from today.
Researchers analyzed stool samples from eight countries.
