Whether humans can recreate the earth's environment, Biosphere 2 tells us: Wash and sleep.

Flying away from the earth now seems to be an effort of the scientific community, especially for Mars and some livable planets, but those livable planets are far away and cannot be reached by the existing technology, and this direction is only to move to the near-earth planet-Mars, and then carry out environmental transformation.

According to the booming technology, people seem to see the hope of moving to Mars. Coupled with the enthusiastic propaganda of some people, Martian immigrants seem to be close at hand, but can people really move to Mars with the existing technology? Re-create an earth environment on Mars?

Although we can't confirm this speculation on Mars, the pace of human experiments has never stopped. Once realized, one of the most exciting scientific research projects praised by American scientists after the moon landing program means that human beings are gods and have the ability to rebuild the earth. This experiment is the famous Biosphere II.

Maybe we first came into contact with the term Biosphere 2 in a biology textbook. What an exciting and desirable experiment this is. Some people may ask: Why is there no such a huge experiment now? That's because the Biosphere 2 experiment failed, and human beings failed to play the role of God.

Ever since mankind stepped into space in the last century and realized the rich resources of the universe, it has always wanted to simulate an earth ecosystem. In order to be able to migrate to other planets, Biosphere 2 was born under this background (many people wonder why it is called Biosphere 2? Because the earth itself is a biosphere (1)

Biosphere 2 lasted 8 years and cost 654.38+0.5 billion US dollars. It's almost completely closed. It has five biological communities: tropical rain forest, savanna, swamp, desert and ocean, and two artificial biological communities: residential area and agricultural area. There are about 4000 species including animals, plants and microorganisms in the circle, which can be regarded as a miniature version of the earth.

199 1 On September 26th, 2008, four men and four women scientists stepped into a closed door and started an unprecedented task. In order to test the effect of complete isolation from the outside world, people in the circle need to be self-sufficient without any supplies. At the beginning of the experiment, all the scientists involved in the experiment were smiling.

However, as time goes by, things are not as good or even bad as expected. Scientists are faced with a series of problems in the experiment, such as food shortage, malnutrition, oxygen reduction (which is impossible according to the earth's environment), gas escape, water cycle imbalance and so on, which all imply the failure of the experiment.

With the takeover of Biosphere 2 by Columbia University and the development of tourists, it also means the failure of the experiment. Biosphere 2 has also become the laughingstock of science, even being ridiculed as "extravagant scientific fantasy". Even now, such a large-scale simulated biosphere only exists in science fiction movies, but in my mind, Biosphere 2 is definitely a beacon in human history.

The failure of Biosphere 2 tells us that it is impossible for human beings to recreate an earth environment. Now we can't leave the earth and move to other planets. How weak human beings are in front of nature. The earth is not a laboratory, but our home.
