Can Mars become a second home for mankind?

How to breed life on a planet and what conditions are needed? Modern science tells us that this planet needs to be a terrestrial planet first, and then its volume and mass cannot be much smaller than that of the earth. Otherwise, it is difficult to condense into a thick atmosphere outside. Without the atmosphere, it would be exposed to all kinds of radiation in space, and there would be absolutely no life. Of course, the most important thing is that this planet should be in a livable zone like the earth, and it is best to be at a moderate distance, not too far and not too close.

What does this mean? Here, let's take the solar system as an example. In the solar system, Venus, Earth and Mars are all in the livable zone of the sun. However, because Venus is too close to the sun, Venus is very hot, and the temperature is as high as Baidu, which is not suitable for the birth and gestation of life at all. It can be said that the environment of Venus is very bad; Let's look at Mars. It is too far away from the sun, so it is very cold and not suitable for human survival.

Moreover, there is another reason. Mars is a little small, so the atmosphere on Mars is also very thin, which can almost be considered as a semi-vacuum state and not suitable for human habitation. However, since the late 1980s, scientists have been clamoring to turn Mars into the second home for future human beings. Before Hawking's death, Hawking also said that in the next 40 years, humans may immigrate to Mars. However, the current situation of Mars is not suitable for human habitation. How can we transform Mars into a "second earth"?

Scientists say that it will take about 150 -200 years for human beings to transform Mars, which shows that Hawking's previous predictions are not reliable. Within 40 years, the atmosphere of Mars has not yet formed, and human beings want to live freely on Mars without wearing any protective equipment and oxygen equipment, which is simply daydreaming.

So, how to transform Mars? Scientists believe that, first of all, a thick atmosphere needs to be formed on Mars to raise the temperature of Mars. How did you do that? After mankind entered the industrial revolution, the climate change of the earth provided us with a direction. We only need to emit a lot of greenhouse gases on Mars, and this plan will take about 100 years. In the first step of the plan, we will build a large number of chemical plants and nuclear reactors on Mars, and then emit a large number of fluorocarbons over Mars through continuous combustion. After that, Mars will become an "ideal atmosphere" similar to the original atmosphere of the earth.

Then, 50 years later, scientists will let Mars have a hearty rainstorm. After that, a primitive ocean will appear on the soil of Mars, and then a pattern similar to the earth will be formed. At that time, Mars has become very warm and humid, which is very close to the early earth. What should we do next? Yes, we can plant plants on Mars and make it full of oxygen.

This process also takes about 50 years. Like the early earth, plants constantly injected oxygen into Mars through photosynthesis. After that, life can be born on Mars. Before emigration, human beings will bring the creatures on the earth to Mars to thrive. After that, mankind will emigrate to Mars, making Mars the second earth and another home for mankind.
