Latest Research on Plastic in the Ocean


Plastic sea trash doesn't biodegrade and often floats at the surface. Bottlecaps, bags and wrappers that end up in the ocean from the wind or through overflowing sewage systems can then drift thousands of miles.
The sheer quantity of plastic that accumulates in the North Pacific Gyre, a vortex formed by ocean and wind currents and located 1,000 miles off the California coast, has the scientists worried about how it might harm the sea creatures there.
A study released earlier this month estimated that thousands of tons of plastic debris wind up in the oceans every year, and some of that has ended up in the swirling currents of the Great Pacific Garbage Patch.
