In fact, from the natural disasters found on the earth today, it is not difficult to see that the earth has seen some frequent changes. Humans can still be on Earth, and how long they will survive is something to consider. In fact, as early as 2017, the National Aeronautics and Space Administration has begun the implementation of the plan to immigrate to Mars. But this is something that really should be done to speed up, after all, the earth does have a lot of problems.
The first humans will travel to Mars in 2024 and may never return to Earth. Many people have doubts about the plan to colonize Mars, and believe that human technology today cannot reach the heights of survival on Mars. One of the most important points is the reproductive and reproductive ability of human beings, it is impossible for humans to mate in space, so where will the next generation of human beings extend from? What is the group of people who go to Mars before 2024 and will not return to Earth?
This kind of problem is worth considering, but the space migration program implemented by the United States is indeed very feasible. The spacecraft of the Mars Colonization Program uses nuclear-powered propulsion dyes, that is, through the fusion of the sun's nuclear methods, which is very safe and fast. The United States will also invest a lot of electrical equipment and machinery into Mars to prepare for the necessary survival.
Mars is currently known by humans as the most likely planet for human survival and habitability. Even the first Martian colonists will have the needs of human survival, all the equipment will go to Mars, and the traditional small-scale peasant economy will be self-sufficient in Mars. The idea is very good, once implemented, it may really bring about a change in human society, and maybe the first "Martian Earthlings" will really not return to Mars, and the future Earth will no longer be the only planet where human beings can survive, which is really good.
The United States' Mars colonization plan has many problems, and some people believe that the first Martian colonists are the test products of the United States, and taking humans as the test objects of the space program, they have absolutely lost their humanitarian spirit, which is unbearable to see and a kind of erasure of human nature. Maybe this kind of plan is really worth discussing. But now that technology has reached colonization mars, the possibility of inhabiting Mars is very small.
If the problem of fertility and mating in space is not solved, then all immigration is really just empty talk. But now that the United States has determined that it will be the first to invest in space migration in 2024, it will be a matter of wait and see.
