Polar bear is the largest land carnivore on the earth, belonging to one of Xiong Ke. It's all white, so it's also called? White bear? , gives the impression of a docile and naive image. But under its lovely appearance, it is indeed a fierce predator. Polar bears are the top predators living in the Arctic, and their maximum weight can reach 1300 kg. Polar bears can run at a speed of 60 kilometers per hour on land. They are also good swimmers, and can swim for more than 90 kilometers at a speed of 10 kilometers per hour. The powerful ability of polar bears also enables polar bears to prey on almost all animals living in the Arctic. But despite this, the living conditions of polar bears are still worrying.
The number of wild polar bears in the world is about 20 thousand. Although the number is relatively stable, there are great problems in their survival. At present, global warming leads to the melting of Arctic glaciers and the reduction of floating ice on the surface of the Arctic Ocean, which makes it difficult for them to prey on animals such as seals, resulting in a serious shortage of food for polar bears. Many polar bears have to swim to another place to find food. Although polar bears are good swimmers, many polar bears are drowned, and many polar bears starve to death because of food shortage. In addition, polar bears will also face human poaching, pollution and industrial activities. It can be said that the current situation of polar bears is worrying.
