If there is no way to migrate to the planet, how long will the earth's resources last for human life?

Without the rapid development of human science and technology, it is impossible to migrate or find other planets suitable for human habitation, then human beings can only rely on the limited resources on the earth, but most of the resources on the earth are non-renewable and will be gone when they are used up. At present, the earth is short of resources. It is estimated that water resources will reach the consumption bottom line around 2050, coal resources will be used for about 170 to 200 years, natural gas reserves for 65 years and oil for 46 years. Many other metal mineral reserves are only enough for human use 18 to 50 years, and only aluminum can be used for about 200 years.

Energy Crisis Due to the limitation of human science and technology, the energy we use is mainly natural gas energy stored on the earth, that is, various minerals, metals, coal, natural gas, oil and fresh water resources. However, with the rapid growth of human population and the selfish nature of human beings, many acts of wasting resources, polluting and destroying the environment make human resources more scarce. As early as 1990, the world began to show signs of energy supply crisis. At that time, few people cared about the energy crisis. Nowadays, people pay more and more attention to the energy crisis, which has become the focus of the interests of all countries on the earth, and even some big countries have launched wars for it.

Interstellar migration in the near future, the limited energy on the earth will be exhausted by human beings, so countries with strong scientific and technological strength are now developing space technology and space technology, hoping to find another planet suitable for human habitation, and also hoping to develop powerful interstellar spacecraft to realize the dream of interstellar migration, or at least find a planet rich in mineral resources, so that the mineral resources on that planet can be transported back to human beings for use, and human beings can continue to survive. But this dream is so beautiful that technology is almost impossible to realize, so we can't have too many illusions about it.

Clean renewable energy At present, the more realistic way to solve the energy crisis is to develop and advocate clean energy, and actively research and develop renewable energy, including solar power generation, huge wind power generation devices, geothermal energy utilization, tidal energy utilization, etc. In recent years, governments all over the world are vigorously promoting it.
