As female polar bears emerge from their dens with young cubs they need to find food quickly, as they have not eaten for the past five months. Without catching a regular supply of food, the mother's milk will fail and her cub will starve to death. With an extrodinary sense of smell, polar bears can detect the scent of a seal over two miles away. This time of life is crucial.
