Polar Bears symbolize the icy landscapes of the far north like no other animal. The bear's way of life — its very survival — is inseparable from the Arctic pack-ice.

Global warming has brought increasing change to the world of ice-dependent species such as the Ivory Gull and Polar Bear. Learn more at BirdNote.org.
