Here, let’s briefly introduce Biosphere 2.

After a few decades, no one will have an impression of Biosphere 2, right?

But in the 1980s and 1990s, this was a scientific research project that caused a sensation around the world. It was no less important than the subsequent starship launches, Mars exploration, Tiangong and Chang'e projects, etc.

Because Biosphere 1 is the earth itself, it is named Biosphere 2. It was initiated by several major American consortiums and a large number of wealthy people. The main investors are the oil king Rockefeller family.

Biosphere 2 was built in the desert north of Tucson, Arizona, USA. The construction period lasted eight years, covering an area of ​​12,000 square meters, with a volume of 141,600 cubic meters. It is composed of 80,000 white-painted steel beams and 6,000 pieces of glass.

Costing $1.5 billion.

People can't help but marvel. At this time, the United States is indeed very powerful and wealthy. You must know that this is completely private financing, and it is invested in scientific research projects that have no profit. The purpose is to create an independent ecosystem and to immigrate to outer space.

After the completion of this miniature artificial ecological cycle system, eight scientists entered "Biosphere 2" in January 1991. According to the plan, they would stay there for two years. Unless a serious accident occurred, they would not be able to come out before the end of the experiment.

of.

In two years, except for providing the first batch of items, including seeds, everything else needs to be solved by themselves. Energy, obtained from the sun; oxygen, produced by the plants they grow; food, grown by themselves in the fields

The meat and protein are obtained from the chickens, ducks, pigs, and sheep they raise. Even the temperature and climate inside are controlled by them and simulate the earth's climate as much as possible. In short, they must try to ensure that this small

The balance of small ecosystems.

Unfortunately, the model of the Earth's ecosystem is not that good. Just a few months ago, in June 1993, the Biosphere 2 experimental project failed.

There are many specific reasons for failure. There are many papers in this area. If you are interested, you can read it yourself.

But no matter what, the failure of Biosphere 2 also caused a sensation all over the world. The main emotion is still regret. It is really difficult to rebuild the earth's ecosystem, and there are many technical difficulties that cannot be overcome.
