Can polar bears survive in warm weather?
Summary: Polar bears are not likely to survive in a warmer world, biologists report. As polar bears lose habitat due to global warming, these biologists say, they will be forced southward in search of alternative sources of food, where they will increasingly come into competition with grizzly bears.
Do polar bears eat seals?
Unlike other bear species, polar bears are almost exclusively meat eaters (carnivorous). They mainly eat ringed seals, but may also eat bearded seals. Polar bears hunt seals by waiting for them to come to the surface of sea ice to breathe.

What is the biggest threat to polar bears?
The loss of sea ice habitat from climate change is the biggest threat to the survival of polar bears.
Do polar bears drink?
It might come as a surprise that polar bears rarely drink water. … Polar bears get their water from the chemical reaction that breaks down fat.
