The Polar Bears of the Canadian Arctic survive primarily on willows and kelp on the tidal flats during summer and autumn. It is essential that the winter freeze comes early so that the ice pack can form to enable the bears to move north and hunt seal. The nutrients and blubber from the seal enable the bears to survive the long, harsh Northern winter.

The effects of Global warming are nowhere more evident than on the banks of Hudson Bay where the winter's freeze is happening later and later. Many bears are falling victim to starvation and many have resorted to killing cubs in order to survive.
