The struggle for survival of a mother polar bear and her two cubs in the Arctic is documented. Environmental changes are speculated to be presenting new challenges to polar bears as well as other Arctic animal species. Timing of the migration cycle is altered as Caribou traverse thinner ice packs. The recession of sea ice reduces the diving platforms needed by hunting walruses. Additional waterfalls from the top edges of vast glaciers appear to be forming as a result of temperature warming. Male polar bears demonstrate the intent to prey on unrelated cubs when seal hunting is nonproductive. Underwater perspectives showcase the superb swimming ability of polar bears, and the affected animals demonstrate adaptability and resilience in response to changes in their environment.
