If the earth can no longer survive, what should human beings do?

The earth has existed for billions of years. If the earth is no longer suitable for human habitation or is on the verge of destruction because it reaches the age limit in the future, then people who depend on the earth can only be destroyed with the earth, or dispersed to other habitable planets to create new living space.

One, the earth will one day be unfit for life. Today, in human understanding, the earth is the only planet that can allow life to exist. However, with the continuous exploitation of energy, environmental pollution, waste of resources and the aging of the earth, the future earth will definitely be uninhabitable. By that time, people living on the earth will lose their place of residence and will definitely look for a new planet to live on. If the level of science and technology does not reach the time when it cannot travel light years, and there is not enough financial and material support, then the rest of mankind will go extinct.

Second, the deterioration of the earth's environment will eventually lead to the demise of mankind. Nowadays, human beings are crazy about absorbing the resources of the earth to develop themselves. Trees collapse, air pollution and garbage are countless. The earth has been damaged by many holes. If human beings do not know how to cherish the earth, when the earth is no longer suitable for human habitation and naturally begins to rebound to human beings, then human beings will only go extinct. Because it is too difficult to find a living planet with current technology, and with the level of human science and technology, it is not yet qualified for interstellar migration. The universe is so big, it can be said that the earth is tailor-made for human beings, so there are talents on the earth. And the next planet, there may be other creatures in charge, and humans don't know what fate awaits us when we go to the next planet.

Third, scattered interstellar migration. If human beings want to go to interstellar migration, they must be scattered to different planets. Because the earth is dying because of the heavy population burden, only by dispersing immigrants can the life of the next planet be longer.
