Nope, it’s not going away.

It’s the smallest pieces that are of most concern, the “bite-sized” pieces that are interacting with the food chain: bottlecaps, bags and wrappers.

Plastic sea trash doesn't biodegrade and often floats at the surface, coming from overflowing sewage systems and 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.

Plastics have entangled birds and turned up in the bellies of fish, and one paper cited by the NOAA estimates 100,000 marine mammals die trash-related deaths each year.

Only humans are to blame for ocean debris. Only humans can do something about it.
