Here's why:
* Ice and Snow: Polar bears rely on sea ice for hunting seals, their primary food source.
* Thick Fur and Blubber: They have thick fur and a layer of blubber that insulates them from the cold.
* White Fur: Their white fur provides excellent camouflage in the snow and ice.
If a polar bear were to live in a hot area, it would quickly overheat and struggle to survive.
