When the earth's resources are exhausted, can we move to other planets?

Almost impossible. First of all, mercury is too hot, and the moon has no atmosphere (of course, you can dig holes near the poles with water to live). Mars is similar to the earth, but scientists are still desperately looking for water on it, and it is too far away, the atmospheric composition is not good, and the transportation cost is very problematic. Jupiter's surface howls every day, and those small satellites can still be considered. It's too cold, stay away from the sun. Anyway, we can't go anywhere with the existing space transportation technology. The nearest planet outside our solar system, proxima centauri, is also 4 light years away. Unless we get the wormhole out, we will still die. Let's protect the environment and realize sustainable development.
