Polar Bears Face Steep Declines

A new study from the U.S. Geological Survey finds that polar bears will likely see a sharp drop in their population in most parts of the Arctic Ocean if greenhouse gas emissions continue at their current rates. Researchers said those emissions are causing the accelerated melting of sea ice, which the bears depend on. They use floating sea ice as platforms to hunt for their prey. "Substantial sea ice loss and expected declines in the availability of marine prey that polar bears eat are the most important specific reasons for the increasingly worse outlook for polar bear populations," said Todd Atwood, USGS research biologist and lead author of the study, in a statement. — Read it from Reuters via Yahoo
