WASHINGTON (Reuters) -- Old toothbrushes, beach toys and used condoms are part of a vast vortex of plastic trash in the middle of the Pacific Ocean, threatening sea creatures that get tangled in it, eat it or ride on it, a new report says.

 

Because plastic doesn't break down the way organic material does, ocean currents and tides have carried it thousands of miles to an area between Hawaii and the U.S. West Coast, according to the study by the international environmental group Greenpeace.

 

This swirling vortex, which can grow to be about the size of Texas, is not far from the Northwestern Hawaiian Islands, designated as a protected U.S. national monument in June by President George W. Bush.

 

The Greenpeace report, "Plastic Debris in the World's Oceans" said at least 267 species -- including seabirds, turtles, seals, sea lions, whales and fish -- are known to have suffered from entanglement or ingestion of marine debris.

 

Some 80 percent of this debris comes from land and 20 percent from the oceans, the report said, with four main sources: tourism, sewage, fishing and waste from ships and boats.

The LA Times ran an excellent, multi-part series on the state of the world's oceans a few months ago, including discussions about the Pacific trash plume. If you're really interested in this topic, I'd suggest giving that a read as well.
