Polar bears do not live in the rainforest but they do depend upon it for the oxygen it produces.
A polar bear is a mammal and all mammals need air to breath.
Arctic ice is melting from global warming. Bears need the ice to catch seals which they rely on for food.
A polar bear would need to adjust a lot of things in order to survive in a desert. Without air conditioning, or millions of years to evolve, a polar bear would likely die in the new environment.
Actually, the polar bear spends most of its time on land or ice flows hunting for seals. It enters the water only out of necessity.
