Why do scientists point out that most humans will land on Mars in the future?

In the future, the earth's resources will not be enough to feed too many people, and the earth's environment will deteriorate day by day. Immigration to Mars is the only way. Mars is the most likely planet to migrate.

First of all, the number of human beings has increased dramatically, so most people will emigrate to Mars, which is most similar to the earth's environment. The distance from Mars to the sun is about 1.5 times that from the sun to the earth, and the Martian year of 1 (period of revolution) is about 1.88 Earth year. The inclination of the rotation axis of Mars relative to the orbital plane is about 25. 19 degrees, which is also equivalent to that of the Earth. Because the inclination of the axis determines the change of seasons throughout the year, Mars has the alternation of seasons similar to that of the earth, and human beings first pointed the goal of "colonial planet" to Mars, which is the most similar to the earth. People can build a large enclosed house on Mars. In the closed place, the atmospheric pressure is too low, so it is not a problem. Oxygen can be extracted from the Martian atmosphere, and water can be obtained from the soil, which can be drunk and planted after purification. The gravity of Mars is only one third of that of the Earth, which makes the construction work much easier. On Mars, people don't even have to adjust their living habits, and they implement an 8-hour working system, because the rotation period of Mars is very close to that of the Earth, about 24 hours.

Since most human beings will emigrate to other planets in the future, it is necessary to know in advance that Mars is the extraterrestrial planet that human beings know the most at present. The exploration of Mars began as early as 50 years ago, and many experimental projects are being carried out to observe and explore Mars. In this process, people's understanding of Mars is deepening. Scientists speculate that Mars billions of years ago probably had a thick atmosphere, water, oceans and even life, just like the earth today. However, because the gravity of Mars is too small, atmospheric molecules keep fleeing, and Mars becomes as cold and dry as it is now, and ancient life disappears or hides underground. In addition, it has been confirmed that there is a small amount of methane in the atmosphere of Mars, and its source is still a mystery. It may come from a chemical reaction, or it may be produced by bacteria-if the latter is strong evidence of life on Mars.

Scientists believe that most human beings will emigrate to Mars, because it is inevitable that human beings will emigrate in the future, and Mars is the most similar to the earth and knows the most at present.
