Bering Sea Ecosystem in Trouble

Steve Heimel of the Alaska Public Radio Network reports on the decline in an array of wildlife species in the Bering Sea. Some in the area say the trouble is due to overfishing of pollock by the region's factory trawler fleet. A possible downgrading of the northern sea lion from threatened to endangered status could force a sharp cut in pollock harvests and a new battle over the Endangered Species Act.
