Marine plastic pollution 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.
The Ocean Cleanup. / 51.92083°N 4.46833°E / 51.92083; 4.46833. The Ocean Cleanup is a nonprofit environmental engineering organization based in the Netherlands that develops technology to extract plastic pollution from the oceans and to capture it in rivers before it can reach the ocean.
Research shows that marine plastic pollution has impacts on marine ecosystems and economic activities at various levels, but further studies are currently being conducted to thoroughly investigate the size of such impacts in the Mediterranean area, both on marine biota and on human health.
Marine plastic pollution could rise 2.6 fold by 2040 if legally binding global policies are not introduced, it predicted. The study looked at surface-level plastic pollution data from 11,777 ocean ...
It is impossible to know for sure, but it is estimated that about 150 million metric tons of plastic exists in our oceans. Plastic pollution makes up 80% of all marine debris from surface waters to deep-sea sediments.
The hydrophilic properties of polyethylene polymers increase as the material experiences degradation and oxidation, which causes polyethylene to become less recalcitrant. [3] Lipases, esterase, endopeptidases, and other extracellular enzymes then further degrade the polyethylene polymers. [3]
The film explores environmental issues affecting oceans, including plastic pollution, ghost nets and overfishing, and argues that commercial fisheries are the main driver of marine ecosystem destruction.
Of the 300 million tons of plastic material produced each year, over 14 million tons end up in the ocean, and plastic production is continuing to increase. Marine litter as a whole is imposing environmental threats to marine ecosystems and policy solutions are crucial to better the ocean.

The manta trawl is useful for collecting samples from the surface of the ocean, such as sampling the plastic pieces making up the great Pacific garbage patch as well as the associated plankton .
