Other polar bears may kill young polar bears
Humans hunting them
Polluted air
Oil drilling
Other industrial disturbances
Bears have no predators other than man. They are not being killed by disease. So apart from global warming the only other way they die is by hunting.
Hunting of polar bears is allowed to native groups in all the countries around the Arctic Circle. There is a quota allowed. In 2011 the quota for Canada is 500 bears. In 2011 in Russia the quota was set to zero. No bears were allowed to be hunted.

Global Warming.
Polar bears are not a cause of global warming. They are being affected by climate change in that their habitat is decreasing in size (as the sea ice is melting).
Countries and their citizens are trying to slow and maybe even stop global warming. This is the only thing that will help polar bears.
Because of global warming, you can't hunt polar bears
