Polar BearsDVD - 2008
Polar bears are living on borrowed time. They are the descendents of grizzlies, long ago evolved to live and hunt on the frozen ice of the Arctic. Winters have become warmer, the ice is disappearing, and food is scarce. Bonus program spotlights a mother grizzly bear teaching her cub how to pluck salmon from near the McNeil River Falls in Alaska.
