The earth is the home of human survival, and the ecological environment on the earth is also the foundation of human survival.
However, it is undeniable that the earth is an extremely small existence in the universe, human science and technology are also developing, and the longing for extraterrestrial immigration is becoming stronger and stronger, but can we immigrate to alien planets "carefree", or even "move"?
The idea has been raised as to whether humans can survive in a closed environment.
And so an experiment was born.
8 scientists, 4 men and 4 women, they were locked together and conducted experiments for nearly 2 years, but the results were shocking, human beings have been "trapped" on the earth?
So why do scientists come to such conclusions, and why can't humans survive in a closed environment?
This also reveals the arduousness and difficulty of extraterrestrial immigration, so how should human beings choose to survive on alien planets?
1. Human beings cannot survive normally in a closed environment.
The so-called "closed space experiment" is an idea of human beings living in a different environment, and the process of the experiment is to live in this closed space, so in 1991, there was such an experiment, that is, the "Biosphere II" experiment known to the mainland.
The Biosphere 2 experiment was a miniature artificial ecological circulation system, in which eight scientists were involved, including four male scientists, Wu Jianxiong, Liu Yingde, Wang Jun, and Zhang Wenhan, and four female scientists, Ma Wei, Wang Jianhong, Zhao Hong, and Wu Yuping.
They were enclosed together for almost two years to conduct experiments, which were originally designed to test the ability of humans to survive in an enclosed space, where they would conduct experiments on artificial ecosystems in a closed laboratory with an area of 1.2 hectares and a volume of about 35,000 cubic meters.
This volume is also enough to ensure the life of 8 scientists, and the environment in the laboratory is also a suitable environment for human beings, so after the 8 scientists entered, everything was arranged smoothly.
They live a self-sufficient life every day, including growing vegetables and raising animals such as chickens and ducks, which are also part of the ecosystem, providing oxygen and food for humans, as well as disposing of carbon dioxide and sewage emitted by humans.
But what the scientists didn't expect was that in the middle of the experiment, they actually encountered a "famine", and the reason for the starvation of the eight scientists was that the vegetables they planted died.
Why is that?
After investigation, they found that it was the lack of oxygen in the ecosystem that led to the death of vegetables, and the reason for the lack of oxygen in the ecosystem was that the consumption of oxygen exceeded the supply capacity of the ecosystem.
After the experiment, scientists concluded based on the results of the experiment that it is difficult for humans to survive normally in a closed ecosystem, because the earth's ecological environment itself is a large and complete ecosystem, and human understanding of this ecosystem is very limited, let alone replicated.
2. The complexity and irreproducibility of the Earth's biosphere.
On the one hand, the complexity of the earth's biosphere is reflected in the fact that the earth's biosphere itself is composed of a variety of organisms, and the interaction between them is also very complex.
More importantly, the earth itself is a mobile ecosystem, which will adjust the biosphere accordingly according to its own development and changes, thus ensuring the stability of the ecological environment.
However, in the Biosphere 2 experiment, the ecological environment they created is a static environment, and the ecosystem on the earth cannot be stationary, so it is difficult for humans to replicate a complete ecological environment, and it is precisely because of this that it is difficult for humans to survive in a closed environment.
So people came up with another idea, which is to reshape the planet.
Planet modification is the process of replicating Earth's ecosystems and transplanting them to other planets, but this is also fraught with difficulties.
First of all, it is very difficult to transform the planet, because the ecological environment on the earth is very complex, but on the alien planet, our understanding of the planet is very limited, let alone copying, and secondly, the environmental differences between the planets are very large, such as the temperature on the earth is a full illustration, the temperature on many planets is very low.
If human beings don't modify it, then they won't be able to survive on this cold planet at all, so it's very difficult to modify the planet.
Although it is very difficult to modify the planet, it does not mean that the earth is the eternal home, and people's exploration of extraterrestrial immigrants has never stopped.
As a result of human exploration, various experiments in artificial ecosystems have also been born.
In 2014, the mainland also released the Yuegong-1 experimental device, which was developed by the mainland in 2011, and 2011 was the time when the mainland began to implement the Mars-500 program, which is a kind of idea for the continent to experiment with the alien living environment.
Therefore, the Yuegong-1 experimental device is also in this sense, the Yuegong-1 experimental device is also a closed ecosystem, and its structure is very exquisite, very much like a "Moon Palace".
In 2014, the mainland announced the design drawings of the Yuegong-1 experimental device, but the Yuegong-1 experimental device was not used in extraterrestrial exploration, but was used in the training of mainland astronauts, and the system has been widely used in the mainland's astronaut training.
3. Bottlenecks in permanent settlement.
Although the idea of human exploration of alien migration is full of temptation and makes people full of hope for their future life, it will take a lot of time and expensive expenses for this set of facilities to take shape, and more importantly, it will also cause some other problems when humans settle permanently.
For example, the Mars-500 program, the Mars-500 program is an idea of extraterrestrial migration on the mainland, but at present, human beings still do not have the ability to completely replicate the ecosystem on the earth to Mars, so in the process of exploring the Mars-500 program on the continent, many problems have also been found.
The main reason is that the gap between Mars and the Earth is too large, and to permanently settle on Mars, it is necessary to form a stable atmosphere on Mars first, but the atmosphere on Earth is formed after hundreds of millions of years before forming the current stable atmosphere.
Therefore, it will take hundreds or even thousands of years for humans to form a stable atmosphere on Mars, which is why humans cannot move to Mars in a short period of time to survive.
And there are some other reasons, such as the magnetic field of Mars, the magnetic field of the earth can shield the high-energy particles in the universe, thus ensuring the survival of life on the earth, but the magnetic field on Mars is very weak, so there will be some high-energy particles through the magnetic field, reaching the surface of Mars, which is harmful to life.
Although the water resources on the earth are abundant, on Mars, human beings need to collect and purify water, which is also a project that requires a lot of time and energy.
So for now, humans still can't settle permanently on Mars, but alien immigration is still a tempting idea, so how should humans choose to survive on alien planets?
It is possible to establish a closed environment similar to Yuegong-1 on an alien planet, and human beings can survive in such an environment, but this method also has one of the biggest drawbacks, that is, human beings have not achieved permanent settlement on alien planets, and human beings still need to rely on the earth for survival.
epilogue
Humanity has a restless heart for extraterrestrial colonization, but we should realize that the earth is our only home, and if the ecological environment on the earth is destroyed, then humanity will also lose the basis for survival.
Therefore, human beings should pay attention to the protection and governance of the earth's ecological environment, although human exploration in alien migration is still in full swing, but the premise is that human beings can protect their homeland, can achieve sustainable use of the earth's resources, and protect the earth's ecological environment.
The development of science and technology should be combined with the protection of the ecological environment, and human beings should pay attention to the protection of the earth's ecological environment while exploring alien migration, and should not neglect the responsibility and cherishing of the earth because of the pursuit of new fields.
