Oceans are polluted by plastic particles ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. This material is only very slowly degraded or removed from the ocean so plastic particles are now widespread throughout the surface ocean and are known to be ...
Rivers are the primary transport of plastics into marine ecosystems, sourcing potentially 80% of the plastic pollution in the oceans. [ 110 ] [ 111 ] Research on the top ten river catchments ranked by annual amount of MMPW showed that some rivers contribute as high as 88–95% of ocean-bound plastics, the highest being the Yangtze River into ...
Plastic pollution in the ocean is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
Naryan believes that releasing genetically engineered bacteria into the ocean ecosystems could be irresponsible and have many negative side effects on the ecosystem. [41] As the Ocean Conservatory group states, the solution to the plastic problem does not lie in genetically engineered bacteria, but rather decreasing the plastic input into the ...

In 2019, plastic world production was 368 million tonnes; 51% were produced in Asia. China, the world's largest producer, created 31% of the world total. [109] Through accidental spillage during land or sea transport, inappropriate use as packing materials, and direct outflow from processing plants, these raw materials can enter aquatic ecosystems.
The South Pacific garbage patch is an area of ocean with increased levels of marine debris and plastic particle pollution, within the ocean's pelagic zone. This area is in the South Pacific Gyre , which itself spans from waters east of Australia to the South American continent, as far north as the Equator , and south until reaching the ...
The microorganisms found on the plastic debris comprise an entire ecosystem of autotrophs, heterotrophs and symbionts. [8] The microbial species found within plastisphere differ from other floating materials that naturally occur (i.e., feathers and algae) due to plastic's unique chemical nature and slow speed of biodegradation.
