Life at the edge
The North Pole and the South Pole are icescapes that seem and look very alike, but look closer and you will find they are as opposite as night and day, summer and winter, for the Arctic and Antarctic are literally poles apart.
Life at the Edge, the first of three Ice Worlds programmes, explores life in the polar regions. It focuses on polar bears in the Arctic and emperor penguins in the Antarctic, and how these two very different animals share some remarkable survival strategies.
