Why do some people want to leave the earth and live on Mars?

Because the pollution of the earth's resources is serious, the environment is destroyed a lot and the ecological pollution is too frequent.

The atmosphere of Mars is thinner than that of the Earth, of which 95% is carbon dioxide, 3% is nitrogen and 2% is argon. The equatorial surface temperature of Mars is-1 13℃ at night and 7℃ at most during the day. The average annual temperature of Mars is about-58 degrees Celsius. Oxygen-free atmosphere, freezing temperature and dry surface have become the three major obstacles for human migration to Mars. So, how about using human wisdom and technology to transform Mars into another earth? This idea sounds incredible, but it can actually be realized, and with the technology of 2 1 century, the environment of Mars can be completely transformed in decades. In fact, the most important thing in the idea of Mars becoming the earth is the first step, which is not difficult to achieve: as long as the temperature is raised a little, the earth is now facing a serious environmental problem-global warming. Scientific research shows that this is caused by the increase of greenhouse gases such as carbon dioxide in the atmosphere. The present environment of Mars is just the opposite of that of the Earth. It seems that our earth is going to cool down, and Mars Chaha needs to heat up. Why not let Mars suffer from "global warming"? There are many greenhouse gases such as carbon dioxide in the atmosphere of Mars. In fact, it once had a warm and humid climate, which can be judged from the traces of river scouring on its surface. Until now, the atmosphere of Mars still contains a lot of greenhouse gas carbon dioxide. Now Mars is cold because of its water cycle. Many carbon dioxide in the air is absorbed by water and combined with the surface material of Mars. It is fixed in the form of sedimentary rocks or ice. The early atmosphere of Mars was not dense, and the carbon dioxide was fixed and thinner, so the warm climate of Mars ended. Fortunately, the carbon dioxide lost from the Martian atmosphere did not leave Mars, but was buried in the soil of Mars. As evidence, the permafrost in the Antarctic of Mars seems to be composed of ice and dry ice. Thousands of ice is solid carbon dioxide. To make solid carbon dioxide re-enter the atmosphere, it is enough to raise the temperature on the surface of Mars a little. As long as the temperature on Mars rises a little, a large amount of fixed carbon dioxide will return to the Martian atmosphere. Once the concentration of carbon dioxide in the atmosphere of Mars increases, the greenhouse effect will begin to show its intensity, and the warming process will continue. More carbon dioxide will change from solid to gas. This is the principle of positive feedback between the temperature on Mars and the carbon dioxide content in the atmosphere. It is conceivable that if this positive feedback can be triggered, the long-standing cold on Mars will be reversed in one fell swoop. How does the new weapon that "shelled" Mars start the first shot of Mars transformation and make the temperature of Mars rise a little? The most direct idea is to improve the absorption of solar energy on the surface of Mars, such as sprinkling some black carbon powder on the frozen areas at the poles to enhance the absorption of solar energy on Mars. The ever-changing nanotechnology has given us a better solution. Some scientists imagine that the continuous development of nanotechnology will enable us to master the method of manufacturing nano-robots These invisible robots can be mass-produced and programmed in a unified way. Then scatter them on the permafrost of Mars like dust, and human beings can command hundreds of millions of nanometer armies on the earth, directly decompose substances in soil and ice, and let carbon dioxide, water and oxygen escape from it. If technology permits, nano-robots can use local materials to replicate themselves on Mars, expand the team and transform faster. When the atmosphere of Mars is transformed, human beings will issue instructions to make all these nano-robots jump ship. In situ decomposition. Even if nanotechnology can't reach such a wonderful level for the time being, we can still build a huge orbital reflector with high reflectivity to reflect more sunlight to the surface of Mars. This scheme is not technically difficult, and it can be realized by using the current principle of making solar sails. In order to achieve the positive feedback effect of starting temperature rise, perhaps we need a super-large reflector with a radius of 100 km. The Antarctic ice sheet of Mars reflects sunlight, and carbon dioxide is released while melting ice. If the big mirror is made of solar sail material, the total mass of the mirror will reach 200,000 tons. It is too expensive to transport so much material from the earth. We can consider taking local materials from stars near Mars, such as its moons, and making them locally. The resources needed to start the space factory can be obtained from the satellites of Mars. When you need energy, you can consider building a nuclear power plant. Solar sail technology can respond to the pressure of sunlight, so we can adjust the angle of the mirror appropriately and shine sunlight on the latitude where the surface of Mars needs sunlight at will. Now, human beings have synthesized a "super greenhouse gas" that is 10,000 times stronger than the greenhouse effect of carbon dioxide, which is perfluoropropane (C2F2). The soil on the surface of Mars contains carbon and fluorine. It is very convenient to synthesize perfluoropropane artificially on Mars. Therefore, in order to transform Mars, we don't have to stare at carbon dioxide all the time. We only need to build some "greenhouse gas" synthesis plants on Mars, and we can completely transform Mars. Through computer simulation experiments, scientists found that when the concentration of perfluoropropane in the atmosphere of Mars reaches three parts per million, it can trigger an unstoppable chain greenhouse effect and make the temperature of Mars continue to rise. Eventually, Mars will become a warm and humid world. After hundreds of years, the climate will be like spring and the snow will melt. Of course, this powerful weapon must be used with caution, because before we have a comprehensive and in-depth understanding of Mars, people can't judge how much perfluoropropane should be discharged into the atmosphere of Mars. If you put too much, it may make Mars have a high fever and become a "fire" star, which is difficult to get close to. Humans are self-defeating 2 1 century Reviving the scientific and technological level of Mars can completely change the planet. The new Mars is actually more like the early Mars, warm and humid, with rivers and oceans, but unfortunately there is still no oxygen. Working and living on the new Mars, humans may need breathing equipment. The good news is that we don't need to wear pressure suits. We can increase the concentration of carbon dioxide through various methods mentioned above. Increase the atmospheric pressure of Mars to a level that we humans feel comfortable with. With the increase of atmospheric pressure on Mars, humans can begin to build on the surface of Mars. Once the temperature in many parts of Mars is always above 0℃, we can transplant many earth plants to Mars. Species in cold regions such as pine, fir, birch, oak and cherry trees should like the modified Martian environment. The prosperity and expansion of plants will produce a lot of oxygen, which will allow animals on earth to migrate there. In the end, humans on Mars will throw away their heavy oxygen tanks and move as freely as they do on Earth.
