IG Looks at Delays in Polar Bear Listing

This undated photo released by the U.S. Fish and Wildlife Service shows a sow polar bear resting with her cubs on the pack ice in the Beaufort Sea in northern Alaska. The Interior Department's inspector general has begun a preliminary investigation into why the department has delayed for nearly two months a decision on listing the polar bear as threatened because of the loss of Arctic sea ice.
