The extinction of polar bears is expected soon.

The polar bear, which lives on the polar ice-cap, will lose its home and die out.

Melting polar icecaps could also contribute to an increase in sea levels.

Patterns of freeze-up and breakup influence the distribution and number of seals, the polar bear's main prey.

In fact, to move at any speed the polar bear uses twice as much energy as do most other mammals.

To survive, the polar bear must keep its body at the right temperature and store enough energy to last between meals that could be a few days or a few months apart.
