WHAT WOULD HAPPEN IF A POLAR BEAR WAS IN A DESERT? Most likely it will die unless it receives care quickly after. A polar bear's natural habitat is to be in cold weather, and their bodies are adapted to the snow. Humans find deserts hot after a couple of minutes, but we don't have long, thick coats of fur on us. On top of that, a polar bear eats like twenty times what we do. If heat wouldn't kill it, starvation would. I hope that never happens :(
