The area of floating ice in the Arctic sea area is gradually decreasing, with a total reduction of about 20%, making it difficult for polar bears to have a long-term foothold on the floating ice. In addition, some countries hunt and kill a large number of seals, making it less and less for polar bears to prey on seals on the floating ice. When we came to a bay near 80 degrees north latitude on the northwest coast of Spitsbergen Island, the Arctic, We were surprised to shoot the whole process of polar bear fishing. We saw that polar bears changed their habit of feeding on seals and not going into the water and began to jump out of the cold water to catch fish.
 The passage fully shows that environmental changes have changed the living habits of polar bears.
