Floating plastic in the Pacific is mistaken for plankton; threatens wildlife

From Bloomberg.com:

Marine researchers Charles Moore and Marcus Eriksen surveyed the dark water of the Pacific Ocean aboard a catamaran about 700 miles (1,126 kilometers) north of Hawaii in January and found trash everywhere.

They were in the eye of the North Pacific subtropical gyre, where opposing ocean currents form a vortex bigger than Australia, trapping tons of floating debris in its circular flow. Trash that wound up there used to decompose. Now, with 403 billion pounds of plastic produced annually, according to the Houston-based consulting group Chemical Markets Associates Inc., areas of the gyre have turned into a soup of indigestible shards that can break down to the size of plankton and be mistaken for food, endangering millions of fish and birds. “No matter where we go, we find plastic,” said Moore, 60. “The ocean is now this plastic soup, and we just don’t know what that’s doing.”

Marine debris worldwide kills more than 1 million sea birds and 100,000 mammals each year, according to the U.S. National Oceanic and Atmospheric Association. The chemical-laden materials have been found in the stomachs of dead fish and birds. “We know that these plastics can carry high levels of toxins that they collect as they float,” said Eriksen, 40, an oceanographer with Moore at the nonprofit Algalita Marine Research Foundation in Long Beach, California. “The next step is to see if it bio-accumulates up the food chain onto your dinner plate.”

No clean-up efforts are under way, according to the NOAA and researchers. Moore and Eriksen said such an endeavor wouldn’t be feasible because of the distance from land. The oceanographic agency has focused on removing derelict fishing gear threatening marine mammals and corals. The plastic industry is funding litter-reduction efforts.
