Around the Arctic Circle, polar bears are at the top of the food chain. They have no natural enemies and are fearless, living on the ice and hunting seals - their favourite food - with matchless cunning and ability. They roam far and wide, often far south of their Arctic habitat: they are seen regularly in Churchill, Manitoba, and in James Bay. They rarely attack humans, but when they do, they win. Considered wise and powerful by Aboriginal cultures, they have become a symbol of animals threatened by climate change in the Arctic ecosystem. Anthony Dalton has gathered stories of 'Ursus maritimus' from Canada, Greenland, Norway, Siberia and Alaska. Learn about the bears' single-minded approach to life and acquiring food, share hair-raising encounters between polar bears and humans, and marvel at the majesty of this mighty animal.
