Polar

Polar bears live in the Arctic.

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

The aurora is a phenomenon characteristic of the polar regions.

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

Take a moment to imagine what the polar bear's environment is like.

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.

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.

Polar bears are white because they're old bears.

Rising pollution levels contributed to the greenhouse effect that would lead to partially melting the polar ice caps.
