MA682.jpg Arctic polar bear habitat
Polar bear (Ursus maritimus), Canada..Note:  This somewhat illustrates the issue of global warming--the ice forms later and breaks up sooner 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 where the bears around Churchill weigh about 10% less than 20 years ago.
