Plastic waste on a beach in Panama City. Professor Richard Lampitt, of the National Oceanography Centre, in the UK, says technological advances can help, like better filters in washing machines to catch microfibers -- as can industry moves to develop less damaging plastics. Microplastics are not confined to the ocean. Dr. Hardesty said that microplastics could be ingested by smaller plankton and fish on the seabed. They are also found in air particles and can be spread by wind. It is an issue that activists have long warned about even as the fight to clean up the ocean has focused largely on the eradication of single-use plastic products like shopping bags. The amount of plastic that's been dumped into the ocean has been increasing, according to a new study, and the problem will probably get worse. The findings were published on Monday in a new study by the Commonwealth Scientific and Industrial Research Organization, or C.S.I.R.O. In 2018 researchers found that, in terms of weight. How does it get there? Scientists believe that 4.4 million to 8.8 million tons of plastic enter the sea every year. She said she was hopeful that awareness about the pollution would lead to more sustainable policies and shifts in behavior. "These are really important questions to resolve. They can end up lining the foreshore in a thick carpet. Plastic pollution in the sea goes far deeper than the floating Pacific garbage patch (SN: 3/22/18). New research shows that the amount of fragments embedded in the sea floor is far more than the plastic floating on the ocean’s surface. Its prime target now is wet wipes, which are often flushed down toilets and are discharged into the river from the sewers after heavy rainfall. "We need to have our eyes on what the nature of this problem is. They also eliminated fibers or other materials from their count to rule out the potential contamination of the samples. The aim of the study, Dr. Hardesty said, was to put a scale to the problem. A variety of microplastics was even detected in the human gut. Hidden Beneath the Ocean’s Surface, Nearly 16 Million Tons of Microplastic New research shows that the amount of fragments embedded … Microbes and mussel colonies growing on floating plastic often cause the entire mass to sink from the added weight. Once eaten by fish, the microplastics can end up in the human food chain. Costas Velis and Ed Cook are researchers with the University of […] That same plastic can even end up in humans. How much plastic is there? As these fertilizers dry out, some of the plastics can get carried off the land by the wind, or wash directly into rivers. Endangered species of marine mammals and sea turtles are routinely eating or becoming entangled in plastic waste floating in the ocean, according to a new report by the environmental group … “It really points to the ubiquity of the problem. The scientists used a robotic submarine to collect samples of sand and sediment on the ocean floor in 2017. Plastics are so ubiquitous in our lives that there are countless other sources of plastic pollution. That is far more than on the ocean’s surface, and it’s the equivalent of 18 to 24 shopping bags full of small plastic fragments for every foot of coastline on every continent except for Antarctica. Plastic waste has long been a visible — and growing — problem in oceans around the world, with refuse littering the shorelines of once-pristine beaches, stretching out across a wide expanse of sea in the Great Pacific Garbage Patch, and threatening sea life that ingest it. “Most of what ends up in oceans are in people’s hand,” she said. Dr. Hardesty said that it was important to prevent plastic from ending up in the ocean in the first place. In recent years, hundreds of plastic objects have been found in the bellies of dead whales around the world. Luis Acosta/Agence France-Presse — Getty Images, long been a visible — and growing — problem in oceans around the world, use of disposable plastic packaging has surged amid the coronavirus pandemic, Microbes and mussel colonies growing on floating plastic, earlier deep-sea studies of microplastics. About half of the fibers are plastic, many entering the water network when clothes are machine washed. and an author of the study, said in a phone interview on Wednesday.
