Disadvantages of Martian immigrants

Humans want to immigrate to Mars. It's impossible to achieve it with current technology. It's not that people can't immigrate to Mars. But because a large number of human immigrants can't survive well on Mars.

First, the temperature is too low for human survival. First of all, the first problem of emigrating to Mars is the temperature. The average temperature on Mars is 73 degrees below zero, and the temperature of more than 70 degrees below zero is not suitable for human survival at all. Unless you have been wearing a thick cotton-padded jacket, and heating needs a lot of energy. The reason why the temperature of Mars is much lower than that of the Earth is that the atmosphere of Mars is thinner than that of the Earth. No heat remains in the atmosphere, so the temperature is extremely low. There are many ways to solve the low temperature. Scientists once thought about using an oversized magnifying glass to partially amplify sunlight. Shine on the surface of Mars. In this way, the temperature on the surface of Mars is temporarily suitable for human habitation. Although this method is feasible in theory, it is only a theory at present.

? Second, the oxygen concentration is not enough. Another problem that prevents people from moving to Mars is oxygen, which is one of the essential substances for human survival. If you want to emigrate for a long time, people will never go to Mars with oxygen bottles like astronauts. Because in that case, it is not a real immigrant. In that case, the government will have to cut off time and launch a large number of rockets to transport oxygen. This can't solve the fundamental problem of immigration at all, but later scientists found that there were glaciers on Mars. If there is a nuclear explosion, the frozen soil and glaciers on Mars can melt and release water and carbon dioxide. Now through the existing technology, plants are grown in greenhouses by using water and carbon dioxide. In this way, people and plants can't form a simple ecosystem, thus achieving the goal of * * *.

Three. Immigrating to Mars is impossible with current technology. With the present technology, it is still very difficult for human beings to move to Mars. First of all, I want to transport a large number of humans to Mars. The cost of building a spaceship will be prohibitive. Moreover, a series of cultural construction after emigrating to Mars will also consume a lot of manpower and material resources. The most important thing is that it is not completely safe with the current technology. Therefore, human migration to Mars is still a concept at present, but I believe that in the future, human beings will definitely realize their dream of moving to Mars.
