There may be no ice in the Arctic in summer, and polar bears are facing extinction. How to save polar bears?

If there is no ice in the Arctic in summer, as German researchers have said, polar bears will face extinction, and we can only save species, not populations.

First of all, it is not difficult to save a few polar bears, but they can be kept indoors. There are already examples of raising polar bears in some zoos, so it is possible to save only a few, bring them to zoos for breeding, artificially protect and simulate their living environment, keep them in captivity, protect their gene population and release them when the environment permits. This is a model of the giant panda in China.

Second, we can't save on a large scale because we can't change the climate. However, we can't do this on a large scale because the power of nature is too great. Protecting all polar bears and even animal species in the Arctic Circle is simply a pipe dream and impossible. Because after extreme climate change in a place, most animals in that place will always die because of inadaptability, and walrus jumping off a cliff before the Arctic Circle is an example.

Third, we can only expect climate change to make the Arctic a polar environment again. If we just keep the polar bear species, it is ok to pair them and raise them artificially. Although they may lose their hunting instinct after several generations, they are at least better than extinction. However, if they want to live well in the natural state, they can only expect sunny weather, so that global warming will not come again and the Arctic summer will not be ice-free. Only in this way can we preserve the polar environment of the Arctic Circle, and then protect the ecology of the Arctic Circle, and polar bears will naturally not become extinct.

Generally speaking, there is no ice in the Arctic in summer, so we can't make it manually, because we can't make an artificial freezer as big as the Arctic Circle. The polar bear is facing extinction, so we can only promise not to poach and raise it artificially when it is about to become extinct, so as to preserve it as a species.
