How do you write down your thoughts on the road of human migration to Mars?

Thoughts on Reading Re-creating an Earth —— The Road for Mankind to Move to Mars

I found a book on the shelf at home. Its name is "Rebuilding an Earth-The Road for Mankind to Move to Mars". We can see in the newspaper that the earth is short of resources and people are planning to emigrate to Mars. All these are presented to me with accurate figures in this book.

There is no doubt that our transportation is fast and convenient, our residence is warm in winter and cool in summer, and the development of modern civilization and technology makes us enjoy convenience. But don't forget, everything that supports these-mineral energy, and everything that can ensure our survival-is provided by the earth.

In this book, because of the over-exploitation of human resources and the shortage of earth resources, the "greenhouse effect" has appeared. Therefore, mankind is considering building a spare "Earth", and Mars is the number one target. This red planet, perhaps once warm and humid, became the first life paradise in the solar system; Maybe in the distant future, it will be the only planet suitable for us to live in.

However, we face many difficulties. First, we can't solve the problem of radiation all the time, and we can only let all life hide in the sky; The Mars-Phobos system is actually quite unstable; Third, the underground ice melts, and liquid water is squeezed out of the ground by the weight of the upper frozen soil, which means that the stratum will sink; Fourth, Mars, like the Earth, may be hit by small objects.

After reading this book, I can't help secretly worrying about the earth: will it last until the day of human migration? To tell the truth, although there are many places in this book that I can't understand, I also know its general meaning. Immigrating to Mars is a way out that human beings can look forward to, but it is still far away. In the future, man may become the director of the solar system. But no matter which planet they immigrated to and what civilization they developed, their telescopes will always pay attention to the little blue planet in the solar system. Because their genes come from the earth, from that blue ocean. I think that even if people want to emigrate, they should protect the environment of the earth first. After all, this is our base camp and our roots are here.

Let's develop science and technology on the premise of protecting the environment and look forward to the prosperous future of human society.
