On Jan.9,the Fish and Wildlife Service (FWS),the Interior Department agency that evaluates endangered species,was due that day to deliver its ruling on the polar bear.Though FWS had already taken over a year to investigate the polar bear's plight — green groups sued the federal government two years ago to declare the animal as threatened under the Endangered Species Act — the day before the deadline,the agency announced that it would need another month to decide,due to the complexity of the bear's situation.
That situation is as follows:As temperatures warm,the Arctic sea ice that supports the polar bear shrinks,leaving the animals to drown as they are forced to swim long distances between the ice,or simply starve to death.
