See how the loss of Arctic ice affects the survival skills of ringed seals, polar bears, and narwhals. For some, the ice is a way to hunt. For others, a way to keep from being hunted. These Arctic creatures have become masters at negotiating the perils of this frozen world. But, their dependence on the ice is also their greatest vulnerablility. These resourceful creatures are learning to adapt. Not rated. This DVD is copy protected and may be played only on licensed devices. 20150831. Closed-captioned.
