It's about time.

There was this documentary filmmaker on the BBC, talking about how she witnessed polar bears eating each other, because they had no food. Also, she witnessed one drown because the distance between ice floes, was too far.

U.S. wants polar bears listed as threatened

Designation could propel action on global warming

The Bush administration has decided to propose listing the polar bear as threatened under the Endangered Species Act, putting the U.S. government on record as saying that global warming could drive one of the world's most recognizable animals out of existence.

The administration's proposal -- which was described by an Interior Department official who spoke on the condition of anonymity -- stems from the fact that rising temperatures in the Arctic are shrinking the sea ice that polar bears need for hunting.

The official insisted on anonymity because the department will submit the proposal today for publication in the Federal Register, after which it will be subject to public comment for 90 days.

Identifying polar bears as threatened with extinction could have an enormous political and practical impact. As the world's largest bear and as an object of children's affection as well as Christmastime Coca-Cola commercials, the polar bear occupies an important place in the American psyche.

Because scientists have concluded that carbon dioxide from power-plant and vehicle emissions is helping drive climate change worldwide, putting polar bears on the endangered species list raises the legal question of whether the government would be required to compel U.S. industries to curb their carbon dioxide output.
