Is it really possible for human beings to move underground in the future? Probably, underground life is much more realistic than living in space, or looking for the next earth and immigrating from there. And this can only be done by current technology. Now there are many underground research institutes, laboratories and military bases. In fact, to put it bluntly, it is nothing more than solving these problems, such as energy supply, water resources circulation, structural stability of underground facilities, waste reuse, air circulation and so on. Think about alien immigrants again, and the technical cost here will be much higher.

In fact, you see a lot of works that describe the future underground life. Isn't the movie The Wandering Earth the same? Even sunlight can be simulated by projection, and the huge canopy can generate real day and night. If you live underground, will it affect your health? At that time, the government will naturally announce that there are corresponding exercise methods to improve people's immunity.

In addition, whether we live underground depends on the difficulties we encounter. If we only know the problems of global warming, greenhouse effect, melting glaciers and energy shortage, living on the surface can solve these problems, but it is useless to move underground. If, like wandering the earth, we met the Great Ice Age, we naturally lived underground. And if the planet itself is destroyed, maybe we can only emigrate to the planet and find another place.

Due to the great disaster suffered by mankind, a few people turned from the ground to underground life. The original design of this huge underground city can only last for 200 years, and there is only light as the only lighting tool in the city. However, with the passage of time, the year 200 will come soon, and the design life of the urban core will also come soon. There are more and more blackouts in cities, and the light we live on is about to disappear in this shimmering city. One day thousands of years later, an asteroid hit the earth, and human beings needed to go underground temporarily to survive. This is a last resort, not a long-term solution. The goal of mankind is to leave the earth in the future and develop outside the solar system. One day in the future, the sun will run out of fuel, that is, five billion years later, the sun will become a white dwarf, and the earth will cease to exist without the sun. Humans can't stay on the earth, let alone move underground.
