Because the polar bear has been used as a proxy to promote the threat of global warming. Polar bear populations are not actually declining - the species is threatened only if you assume that hysterical predictions of warming are true.
There are no polar bears in Antarctica. It's too cold and there is no food chain there for any animal. Polar bears are indigenous to the Northern Hemisphere. Antarctica is in the Southern Hemisphere.
yes, they are smaller and have not as much hair ;)
Polar bears are carnivorous. Panda bears are nearly complete herbivores. Polar bears are also much larger than pandas.
As much as they want to have.
The polar bear has no actually prey but some polar bears have been known to have been killed bye killer whales and Greenland sharks. Sometimes there has been the polar bear preying on them!!! Small cubs are preyed on by adult polar bears. Humans are pretty much the only other real issue. They can and do hunt polar bears. This is the reason their population went down many years ago to dangerously low levels. The limits on hunting allowed them to regain population.
Polar bears main eat seals, which they hunt from the ice. During summer, when much of the sea ice melts, polar bears find ift difficult to find food.
They are left-handed and can eat up to half their body weight. Polar bears are not left handed stupid!
The polar bear is stronger because it weighs much more than the liger. Polar bears weigh much more than ligers since polar bears weigh 950 pounds to 1760 pounds. Ligers weigh about 800 pounds. Brown bears, like kodiak bears and alaskan brown bears, are also stronger than ligers.
22.43% of polar bears are blubber, which protects them from extreme enviroments. Hope this helps!
Since polar bears are not territorial, they will simply range around until they find a suitable food, usually avoiding other bears.
No. The wolf is much smaller than a polar bear. Polar bears are big and mean.
There are rare cases of adult male polar bears eating young bears. Polar bears are NOT the same as black or grizzly bears - those species are known to kill cubs in an effort to send the female back into heat in order to mate. This is called infanticide and this behaviour has not been observed in polar bears. If an adult polar bear kills a cub it is most likely cannibalism, driven by desperate hunger. Due to rapidly shrinking Arctic sea ice, polar bears don't get to spend as much time on the ice hunting their primary source of food: seals. So if polar bears are stuck on land for longer periods of time, they may become more desperate for food sources.
