Despite laws and regulations, plastic continues to enter the world’s oceans at a rate of about 5 million pieces a day. The bulk of it enters as litter transported via storm drains and watersheds.
Once in the ocean, some of these plastics- Polycarbonate, Polystyrene, and PETE- sink, while LDPE, HDPE, Polypropylene, and foamed plastics float on the surface. Sunlight and wave action cause these floating plastics to fragment into increasingly smaller particles that never completely disappear- at least on any documented time scale. Considering that the ocean’s total plastic burden is currently estimated at over a trillion tons, the damaging impact to the ecosystem ,marine life and, ultimately, us, is huge.
