Polar bears are the newest addition to the list of endangered animals. The polar bears are arctic animals that are huge and similar to grizzly bears of the US. One of the main reasons why they are disappearing is global warming. The polar bears are used to extreme cold temperatures and their body is built for the cold. However, when the weather is excessively hot, the polar bears cannot survive.
In the Arctic region, several polar bears have disappeared, and now scientists are pondering over the fact as to how many of them are left. No scientist has been able to figure out how many of them are exactly there. One research claims that there are nearly 22,000 polar bears living in the wild, and that majority of these bears live in the icy regions of Canada.
The main reason why we do not have a number for polar bears is because they are too difficult to find and also they are spread out in huge areas. Some of the regions in Canada and the Arctic Circle are inaccessible to human beings. Most of the polar bears live in Canada and some live in Arctic Circle and in North Pole. There are a few of them that live in Canada, Russia, Denmark and even Norway. However, the arctic ice and other glaciers are now melting across the world because of global warming. The polar bears are losing their habitat because of the melting snow caps and they are falling numbers.
The polar bear does not have any predators and they live in areas where there are no humans.
