polar bear

Polar bears think that since they have arrived at the North Pole, there should be many such bears named after this place. It was not until the Arctic Circle that I discovered the harsh living environment, which is really unimaginable for people living in temperate zones. In addition to the island desert near the Arctic Circle, some lower plants such as moss are struggling, and the rest are boundless in the ice sea. Polar bears are stationed in the vast ice area between 80 degrees and 85 degrees north latitude all the year round. When we say that they are resident, we mean that they never leave the bitter and cold place in the extreme north all year round, whether it is extreme day or night, whether it is foraging or breeding. This is the first time I have seen a polar bear. It is not very big, its body is flexible, and its fur is white. It is estimated that there is limited oil and water in its stomach, and it has not been dyed yellow by the fat of ringed seals. It runs fast on the ice, like an elf made of silver foil. Four big palms, like white cattail leaf fans, flapped in an orderly way in the ice and snow, flying up and down, with elegant posture. Although its hearing is not developed, the tourists have learned their lesson completely and kept silent. In addition, the atomic icebreaker does not emit any smell. It has never been frightened, and it still maintains a happy attitude. When the sea ice scattered in the running, it didn't want to, didn't slow down, and didn't hesitate at all. With the help of running inertia, it jumped forward, drew a burning white light in the air and landed firmly on another piece of ice floe. In front of it, the ice area cracked, so it jumped step by step, as if crossing an invisible railing, up to 5 meters at a time. Most of the time, it judged correctly, landed safely (to be precise, it was safe to freeze), and then the horse (to be precise, it was a bear) kept running. Sometimes it's bad luck, falling into the cracks in the ice and being submerged by the blue sea. As cool as a cucumber, the polar bear didn't feel anything unusual. He immediately raised his head and began to paddle freely in the Arctic Ocean. At the moment of falling, the polar bear was instantly soaked by ice water. Will it be cold enough to make people shiver? In an instant, tears welled up in my eyes. Not only lamented the difficulty of the polar bear's survival, but also was moved by its smooth swimming stroke. The clear ocean is like blue crystal, and polar bears are as elegant as blooming Bai Lianhua when floating. I know it doesn't seem appropriate to describe a fierce animal weighing hundreds of kilograms, but when you see this huge white spirit dancing its limbs lightly and leisurely on the dark blue sea floating with ice floes, like a giant jellyfish, you can only make such an incredible sigh. Polar bears can paddle freely, and their broad front paws are like paddles, pushing down and rowing backwards to provide power for their huge bodies. The hind legs are basically in the same place, which acts as a rudder and controls its swimming direction. Polar bears are complete carnivores and have no plants in their diet. This can't blame its unhealthy eating habits, which is forced by the harsh environment in the Arctic. Native arctic plants, mainly mosses and lichens. At the lower latitudes of the Arctic, you can occasionally see a drop of green, and at the higher latitudes, almost nothing grows. Polar bears can only eat pure meat all their lives and live alone in the ice and snow. It may be the loneliest animal on earth. If the Arctic ice floes melt, or even there is no ice, polar bears will lose their homes and cannot survive. Someone asked an animal expert: "Can polar bears immigrate to the South Pole, let them adjust their diet and practice eating penguins from now on?" The animal expert said, "Polar bears don't want to leave the North Pole." If the Arctic ice completely melts, polar bears lose their homes to recuperate, and finally starve to death and become tattered black skin, human beings, including you and me, are to blame.
