Polar Bear Status Report
Polar bears are a potentially endangered species living in the circumpolar north. They are animals which know no boundaries. They pad across the ice from Russia to Alaska, from Canada to Greenland and onto Norway's Svalbard archipelago. Biologists estimate that there are 20,000 to 25,000 bears with about sixty percent of those living in Canada.
The main threat to polar bears today is the loss of their icy habitat due to climate change. Polar bears depend on the sea ice for hunting, breeding, and in some cases to den. The summer ice loss in the Arctic is now equal to an area the size of Alaska, Texas, and the state of Washington combined.
