In the gateway to the Arctic, fat, ice and polar bears are crucial. All three are in trouble

  • BY SETH BORENSTEIN AP Science Writer

In the gateway to the Arctic, fat and sea ice are crucial, intertwined and dwindling. And scientists say because of that polar bears are in trouble. In Churchill, Canada, the polar bear capital of the world, scientists say there are now about half the polar bears as there were 40 years ago. Polar bears are losing sea ice that they use as a base for seal hunting, so they are going hungry longer in the summer. Even tiny plankton, the base of the food web, is going low fat. And that's bad for the region because fat is crucial for survival here.
