Why don't penguins get eaten by polar bears?

No, because they are not in the same place. 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.
