Plastic trash vortex menaces Pacific sealife-study

WASHINGTON, Nov 6 (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 US 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 US 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 per cent of this debris comes from land and 20 per cent from the oceans, the report said, with four main sources: tourism, sewage, fishing and waste from ships and boats.

The new report comes days after the journal Science projected that Earth's stocks of fish and seafood would collapse by 2048 if trends in overfishing and pollution continue.

Two weeks ago, the US Institute of Medicine said the benefits of eating fish outweigh the risks of toxins detected in the animals.
