Dry air swirls around empty frozen lands, glaciers move slowly across the waters, winter darkness envelopes the areas day and night. Still, there is life at the poles -- polar bears and penguins, scientists and explorers, berries and mosses. Learn how seasons affect life in the Arctic and Antarctic, how wildlife survives, and what scientists can learn from studying these regions.
