Why are there no polar bears in Antarctica?

What will happen to polar bears in Antarctica is second, and the local indigenous "residents" seals and penguins suffer more. It is not easy for polar bears to catch seals in their hometown. Sometimes they have to wait for hours in the ice cave. Even so, they often draw water with a sieve. Because seals who have danced with polar bears for a long time have a set of tricks to deal with polar bears. Antarctica is different. There are no polar bears there. The seals and penguins there don't know how to avoid it at all, so they have to be "slaughtered" and the only consequence of waiting for them is extinction. In the global warming environment, Antarctica may not become a "refuge" for polar bears. Even if you "immigrate" to the South Pole, you can only do it as a last resort. Can humans consider turning them into "space bears"? The North Pole is an ocean and the South Pole is a continent. The former is a land-covered ocean, and the latter is a land-covered ocean. The natural environment must be different, and polar bears must not adapt to living there. Polar bears can be released to the South Pole, but they meet penguins. It's like if we put the lion on the grassland in a chicken farm, of course the lion can survive, but the chicken farm will be turned upside down. There is no problem with the survival of polar bears, but the survival of penguins and seals is a problem. Source: Composition Weekly Primary School Grade Three Edition
