Is Global Warming Turning Polar Bears into Cannibals?
Filed under: add to del.icio.us
A new study has found that polar bears in the southern Beaufort Sea may be turning to cannibalism because longer seasons without ice prevent them from obtaining their natural food. The study reviewed 3 cases of cannibalism in the bears, which typically kill each other only for population control, dominance, or reproductive advantage. Environmentalists fear shrinking polar ice may soon lead to the extinction of the bears.
