     • But the approach works by looking for plastic's reflected light signature in the water. And early trials conducted by the UK's Plymouth Marine Laboratory have been very encouraging. "You're never going to see an individual plastic bottle floating on the sea, but we can detect aggregations of this material," Dr Lauren Biermann told BBC News.

   How much plastic is floating in the oceans?

   • More than 171 trillion pieces of plastic are now estimated to be floating in the world's oceans, according to scientists. Plastic kills fish and sea animals and takes hundreds of years to break down into less harmful materials. The concentration of plastics in the oceans has increased from 16 trillion pieces in 2005, data suggests.

   Where does ocean plastic come from?

   • The highest concentration of ocean plastic is currently in the Mediterranean Sea, with some large floating masses found elsewhere including the Great Pacific Garbage Patch. The authors also suggest that the changing levels of pollution before 2000 may be due to the effectiveness of treaties or policies that govern pollution.

   How much plastic is accumulating on shorelines?

   • A 2019 study estimated that 67% of all buoyant macro plastic (bigger than .5 centimeters) has accumulated along shorelines, approximately 110 million tons. That's far more than the estimated 31% that has accumulated in coastal waters and the roughly 1% found offshore or circulating in distant gyres. Please support our efforts, donate today!

   What happens if plastic sinks before reaching the open ocean?

   • It is believed that a significant part of plastic sinks in these places before reaching the open ocean. – This tool represents the trajectories of floating plastics. Not all of them will keep their buoyancy long enough to reach offshore locations, and a significant part of them will sink in the rivers and estuaries because of that.

   Why is ocean plastic a problem?

   • Ocean plastic can generate a host of environmental hazards, from the entanglement of creatures such as turtles, to consumption by birds and fish as it is mistaken for food. The problem is so widespread it has given rise to the "plastisphere" – a term used for ecosystems that have evolved to live in human-made plastic environments.

   How much plastic is in the Great Pacific garbage patch?

   • Microplastics account for 94% of the estimated 1.8 trillion pieces of plastic that make up the Great Pacific Garbage Patch (Credit: The Ocean Cleanup) Although this raised the profile of the world's plastic problem, it played into myths surrounding the GPGP.

    Mar 26, 2013 · The Ocean Cleanup is a non-profit organization developing and scaling technologies to rid the oceans of plastic. To achieve this objective, we use a dual strategy: intercepting plastic in rivers to cut the inflow of pollution, and cleaning up what has already accumulated in the ocean and won’t go away by itself.

    Jan 31, 2022 · About 8 million tons of plastic flow from rivers and beaches into the ocean every year. These plastics are carried by ocean currents and broken down by waves and the Sun into small microplastics. Much of it floats at the calm center of circular ocean currents (called gyres) in large garbage patches.
