In real life, it is unbearable for human beings to give up the earth.
The earth is the only livable planet discovered by human beings so far.
This planet provides all the living resources for mankind.
Specifically, the earth provides the following biological resources for human beings:
1, water.
2. Air. It contains oxygen suitable for human breathing.
3. Suitable temperature.
4. Various organic and inorganic resources.
Judging from the current human discovery, no planet can provide all the above resources for human survival.
Therefore, it is unthinkable to give up the earth.
In the story setting of the wandering earth, in order to find a new livable zone, the earth needs to cross the universe for at least 2500 years.
For such a long time, with the current level of science and technology, it is impossible to build a spaceship that can maintain the living environment for such a long time.
In addition, even if human beings can build a spaceship that can survive for 2500 years, they will need a planet to stay, live there and build their own new home after reaching their destination. ..... spacecraft obviously don't have this condition.
Therefore, if we give up the earth, human beings will eventually be unable to survive.
Therefore, although the present earth (the state set in the story of wandering earth) is frozen because it is far away from the sun, the basic resources have been preserved, which is the material basis for human beings to continue to survive and the basis for human beings to build new homes in the future.
Therefore, in the story of wandering earth, it is impossible for the earth to be abandoned.
In real life, the same is true. ..... So far, the earth is our only home. Only by protecting the earth can we have a happy home. ..... So, the earth can never be abandoned.
