The continent home to the polar bear is North America, particularly the Arctic region. Polar bears primarily inhabit areas within the Arctic Circle, including parts of Canada, Alaska (USA), Greenland, Norway, and Russia. These magnificent creatures are uniquely adapted to cold environments, with thick layers of fat and dense fur providing insulation against extreme temperatures. They are excellent swimmers, often hunting seals, their primary food source, by breaking through sea ice. Climate change poses a significant threat to polar bears, as melting ice due to rising temperatures affects their hunting grounds, leading to concerns about their future survival and ecological balance in the Arctic.
