Why are there no polar bears in Antarctica? The distribution of all animals is a function of luck and history. Having everything you need is no guarantee of being able to reach any point on the globe once you are there because it may not be possible to get there in the first place. Polar bears likely evolved very recently (about 200,000 years to possibly as long as 500,000 years ago) from grizzly bears somewhere off eastern Russia or the Alaskan Panhandle. They are totally dependent upon sea ice for their primary habitat for getting their food (mainly ringed seals and bearded seals). As the world's oceans never have been frozen from the north to the south, polar bears never have had the possibility to reach the Antarctic. Polar bears are strong swimmers but not strong enough to swim to the Antarctic. Some species have wider distributions because their habitats were connected at some time in the distant past. For example, grizzly bears (also called brown bears) live in the USA, Canada, Russia, Spain, Italy and even Norway! They crossed over a land bridge between Russian and Alaska. The same is true for wolves, wolverines, lynx and many other species. However, polar bears would really like the Antarctic. In the absence of polar bears, seals and penguins in the Antarctic are not afraid of predators (except leopard seals and killer whales). A polar bear would have a lot of fun and probably get very very fat! On the negative side, the seals and penguins would be devastated. Polar bears are really better off in the Arctic.

They live in the North Pole, and as the ice caps melt, they are being forced to find other places to live and have been either starving to death or drowning in the Arctic Ocean because the ice is getting to thin and far in between.
Good luck on your project!

they live in north pole, unlike the penguins, in south pole.
global warming means temperature is rising and this causes icebergs to melt faster. resulting in the polar bears' homeland to be destroyed and they might not to able to survive better due to their thick fur coat.

On the poles... that is why they are called polar bears... the melting of ice due to global warming is destroying their natural habitat...

they live up in norther regions of Alaska and mainly in the North Pole. Since the north pole is all Ice and no land, when there is no more ice, they will be crowded for land and will not survive
