The largest ocean-based source of plastic pollution is discarded fishing gear (including traps and nets), estimated to be up to 90% of plastic debris in some areas. [ 56 ] [ 57 ] Continental plastic litter enters the ocean largely through storm-water runoff, flowing into watercourses or directly discharged into coastal waters. [ 58 ]
The state of Sikkim has restricted the usage of plastic water bottles (in government functions and meetings) and styrofoam products. [239] The state of Bihar has banned the usage of plastic water bottles in governmental meetings. [240] The 2015 National Games of India, organised in Thiruvananthapuram, was associated with green protocols. [241]

Global negotiators have agreed to craft a draft treaty to end plastic pollution, a preliminary but crucial step toward tackling one of the most lasting sources of human waste. Environmental ...
[8] [10] There can be many sources of marine debris such as land-based, marine-based, and other anthropocentric activities. Million tons of land-based waste products such as plastics, papers, woods, and metals end up in seas, oceans, and beaches through the wind, oceans currents (five major gyres), sewage, runoff, storm-water drains and rivers.

Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...
Debris on beach near Dar es Salaam, Tanzania Debris collected from beaches on Tern Island in the French Frigate Shoals over one month. Researchers classify debris as either land- or ocean-based; in 1991, the United Nations Joint Group of Experts on the Scientific Aspects of Marine Pollution estimated that up to 80% of the pollution was land-based, [5] with the remaining 20% originating from ...
The plastic industry has responded to the increased interest and concern for plastic pellet loss and pollution sources. Operation Clean Sweep was created by SPI: The Plastics Industry Trade Association in 2001 and joined by the American Chemistry Council with the goal of zero pellet loss for plastic manufacturers.
