Four men and four women carried out experiments in a closed space, and the results showed that human beings had been "trapped" on the earth.

In recent years, the United States has been exploring the ecological environment of Mars in order to better continue the development of mankind. I was surprised to find traces of water flowing on it, and inferred that there might be life on this planet.

As a result, there is a plan to send some residents to immigrate to Mars, and this plan continues to advance. But this does not mean that we have to give up the home of the earth, just for the longer-term development of human civilization.

No matter from air, resources or environment, the earth is the only place suitable for living things. Although human beings want to change the living environment of Mars, it is very unlikely to create a natural protective layer similar to the earth out of thin air. After all, the formation of the atmosphere took billions of years.

So humans thought of creating a living base on Mars with the model of physical protective cover, but is it really feasible?

Closed space experiment-Biosphere II

In fact, this kind of closed space experiment was adopted as early as 30 years ago. At that time, eight scientists from the United States entered a closed cabin simulating space life, which was called Biosphere II. There is plenty of oxygen in it, but there are no tools, so humans need to do experiments themselves.

The initiator of this experiment is not a scientist, but a football player. He tried to persuade the oil magnate to invest in this experiment, and showed that if successful, it would make outstanding contributions to the sustainable development of mankind.

In the 1970s, the confrontation between the United States and the Soviet Union was in dire straits. Two great powers landed on the moon one after another, but the United States was one step ahead of the Soviet Union. This gave Americans great confidence in conquering the universe. The experiment of Biosphere 2 has been mentioned many times, and all mankind has turned their attention to this world-famous "interstellar plan".

Biosphere 2 was chosen in a vast desert in Arizona, USA. In order to change the ecological environment of the simulated earth, the scientists decided to give these eight people an area of 1.3 million square meters, which is enough for them to explore.

This ecological environment includes rainforest desert, grassland ocean, swamp wetland, agricultural planting area and human living area. The most important cycles in the ecological environment are atmospheric cycle and water cycle. If it cannot be implemented, the ecosystem will fail.

So there are not only 3800 kinds of plants, but also many ordinary poultry animals, so let them participate in this cycle. The reason why the earth can run is because of the gravity of the sun and the transfer of light and heat. The photosynthesis of plants in this ecosystem still depends on the sun. In order to ensure its tightness, the whole ecosystem is made into a large container and the ground is closed.

At the same time, in order to increase the accuracy, scientists tried their best to imitate the composition of the earth's crust and achieved realistic results. In addition, there are two air pressure regulators to adjust the internal ecological environment and block all possibilities of contact with the outside world. This is only isolated from the outside world in the ecosystem, not really cut off all contact with the outside world.

The energy in the ecosystem will also be exchanged with the outside world, and people inside can also get the information transmitted by the outside world and judge their current situation, so that they can be fully prepared in case of unexpected accidents. The eight scientists walked into the laboratory with confidence, believing that they could overcome many obstacles according to their own abilities, and fantasizing that they could make great achievements in them.

After all, it is equivalent to a "paradise". But in fact, it is impossible for human beings to replicate an ecological environment exactly like the earth, and the Biosphere 2 experiment ended in failure.

The failure of the experiment

Biosphere 2 is equivalent to a primitive society, and a group of human beings with modern advanced thinking are naturally at a loss when they "cross" back to the past. They found that it takes a long time not only to grow their own vegetables, but also to raise poultry.

In order to solve the current dilemma, scientists must find edible ingredients in the wild. At the beginning, they vowed to live in it for two years or even double it. But contrary to expectations, what made them collapse most was that the environment inside the container began to deteriorate.

Although it took two years from setup to construction, everything was as perfect as ever. No one expected that human participation in the cycle would accelerate the degree of environmental damage. Biosphere 2 has a large area, but the only areas that can produce oxygen are places with green plants, such as deserts, swamps and oceans, which cannot provide atmospheric circulation.

Moreover, with the increase of carbon emissions, the carbon in the soil is stimulated to combine with oxygen in the air to generate carbon dioxide, which makes the oxygen content in the container drop by 7%. At this time, scientists also developed symptoms such as discomfort, dizziness, and difficulty breathing.

Due to lack of oxygen, some lower organisms cannot breathe and die. Animals are one of the messengers by which plants reproduce. Once an animal dies, it will also affect the survival of plants. Researchers have no choice but to manually deliver oxygen to the experimental base, but to no avail. Animals and plants in the base are dying and entering a vicious circle.

Because the living environment has become bad, the relationship between people has become tense. I can't believe the situation encountered this time is so complicated. Moreover, they come from different countries and have different living habits. This self-made life is really painful and uncomfortable. There are more and more contradictions between them.

In the end, the experiment ended in failure, and the bodies of eight scientists were also damaged to varying degrees. The idea that human beings want to create another earth is shattered. It is almost impossible for the United States to immigrate to Mars, and human beings are "trapped" on the earth.

Biosphere 2 failed, but there are many similar experiments. For example, Moon Palace No.1 in China. It is also a small ecosystem, which is to prepare for human landing on the moon. Compared with the experimental base in the United States, Yuegong No.1 is particularly compact, and the most edible plants such as vegetables are planted in it.

It is almost impossible to rebuild an ecosystem, and even if it is capable, the money spent may be borne by all mankind. We are doomed to be trapped on the earth for a long time.

With the development of science and technology, human activities have also caused irreversible damage to the ecological environment. We can't give up the development of this planet and find another way out just because it is getting worse and worse. We must do a good job in environmental protection, resource exploitation and rational development, and reduce carbon emissions. This is the most reasonable plan.
