The polar bear or the ice bear are the world's largest land predators. They can be found in the Arctic, the U.S. (Alaska), Canada, Russia, Denmark (Greenland), and Norway.
These countries either banned hunting or made rules for how many polar bears could be hunted within its own boundaries. These rules help keep the polar bear populations stable. Today, 20,000 to 40,000 polar bears roam the Arctic.
This information helps people understand how endangered the polar bear is how would you feel if the human race was endangered.
There are three main dangers to the polar bear

By the end when the polar bear eats the seal and it could be lethal.
In a recent study done, that was released on July 6, 2009, states that not only is global warming threading the existence of polar bears, but also harmful chemicals that man is releasing into the environment.
Mercury has been found in polar bear bodies. Mercury is ingested by the polar bear through other animals. It can simply start our as a small fish, then as it goes through the food chain, it becomes more and more concentrated. By the time the polar bear eats the seal, the mercury levels could have a lethal effect on the polar bear.
Polar bears live in a very specific. habitat They need the cold, snow and ice of the polar regions. That is why they are called "polar bears" and not "summer bears." Polar bears have very few natural threats in the polar region. Polar bears are on the top of the food chain and there are no other animals in the north that will threaten the polar bears. So why are the polar bears now on the threatened/endangered species list?
Polar bears are not threatened because of other animals or because they are being hunted too much. Polar bears are threatened as a direct effect on how we as humans treat the earth and the environment. People have begun to take the earth for granted. They have treated it as though it is indestructible. When in fact, the earth is destructible, and we are destroying it.
Climate change is effecting the polar bears already. They have to stay on shore more, because the ice forms later in the year and lasts for fewer months. Polar bears need the ice to live. They hunt seals from the ice floes and with less time on the ice. The less time they have to eat. Polar bears do not hibernate. They have to have enough fat storage build up throughout the winter to last them throughout the spring, summer, and parts of fall. So to answer the question, is global warming killing the polar bears? Yes, and we have to begin acting now to help with their survival.

...polar bears shelter their cubs in a safety of their snow dens when they go hunting for food. But as the ice melts, these dens are collapsing on the cubs, leaving them weak and exposed to the extreme weather conditions.
...experts predict that the arctic sea ice could disappear completely in summer by 2040.
More than two thirds of the world's polar bears will be wiped out by 2050, according to a shocking new study.
By then, scientists say, global warming will have melted 42% of the Arctic sea ice which the bears need to hunt and repopulate.
And by 2100, the experts warn only a handful of the...
