Polar bear (Ursus maritimus), Canada Note: This illustrates the issue of global warming--the ice has been forming later and breaking up sooner in recent years in the arctic. Since the bears do most of their hunting on the ice pack for seals this shorter duration of ice limits their hunting time. I have read that many of the bears around Churchill weigh about 10% less than 20 years ago.
