It is impossible for us humans to immigrate to other planets, so what should we do?

Some people will say, isn't there a lot of space? There are countless planets there. When the earth's resources are exhausted, can't we move to other planets?

Scientists have proved that there is no second planet suitable for human habitation at least within 40 trillion kilometers centered on the earth. Humans can't expect to move to other planets after destroying the earth.

Yes, scientists have put forward many ideas, for example, building an immigration base on Mars or the moon. However, even if these ideas can be realized, it is still a distant thing. Besides, how many people can live?

4 "Our earth is so lovely and easily broken!" This is the sigh of astronauts traveling in space and witnessing the earth.

There is only one earth. If it is destroyed, we have nowhere to go. If all kinds of resources on the earth are exhausted, it will be difficult for us to replenish them from other places. We should seriously protect the earth and its ecological environment.
