Polar bears have uniquely adapted to living near the farthest tip of the Northern Hemisphere. They live in the Arctic territories of North America and Eurasia. They are distributed in the following countries: Canada, Russia, Norway, Greenland(Denmark), and the United States of America. In the United States they live in Alaska. Early map population history indicate much larger territories prior to becoming endangered.
Their habitat includes both land and sea ice. Often polar bears live on ice and drift from one area to another. Massive areas break off and shift locations, sometimes putting mother and cubs in danger. In fact baby polar bears can become stranded when blocks drift far apart since cubs cannot swim long distances.
Climate information facts indicate global warming is responsible for altering polar bear habitat, the animals they eat, their behavior, life cycle, and life span. Hunting harvests by indigenous villages are also impacted.
Except in captivity, scientific statistics indicate they may suffer extinction by year 2100. To save them conservation efforts must attack the problem head on. Through evolution polar bears have adapted to the Arctic. Their ecosystem is the most sensitive to climate change.
