We can't now, but we can't deny that we can't in the future. Once, we thought the deep sea was the desert of life. However, we found that the submarine hot spring biological system of deep-sea volcano is an ecological environment supported by chemical energy bacteria. The temperature of hot springs reaches 400 degrees (Venus is familiar with it), and the chemical energy base comes from hydrogen sulfide (Venus sees sulfur). There are even shrimps, crabs and fish, and life is hard. Venus is extremely harsh, but people can't live without dreams. If we transform Venus, what do we need? Biosphere transformation. We need a microorganism that can chemically convert carbon dioxide into oxygen and adapt to the extreme climate of Venus. This behavior is not impossible. Many anaerobic bacteria can survive in extreme environments. You know, in the early days of the earth, it was huge microorganisms that constantly transformed the earth and gradually turned the highly toxic atmosphere into today's environment. Anaerobic bacteria lost to the algae empire. It's just that we can't wait for the accumulation of hundreds of millions of years, and we don't intend to make a wedding dress for the next intelligent creature. This biotechnology needs to have extremely fast reproductive ability, very, very fast.
