What s new in Biosphere 2?

Not yet, not stopping at all!

Reason: The total amount of oxygen decreases due to the oxidation of organic matter in the soil, and the carbon dioxide produced is absorbed by the concrete used to build the building, and does not enter the cycle.

The photosynthetic capacity of the biosphere is insufficient, and the level of carbon dioxide in closed containers rises, more than 10 times higher than normal levels on Earth.

A little more than a year later, Biosphere 2's ecological situation has taken a sharp turn for the worse, with oxygen (O2) levels falling rapidly from 21 to 14, while carbon dioxide (CO2) and nitrogen dioxide (NO2) levels have skyrocketed, the atmosphere and sea water have become acidic, many species have died, and morning glories, which absorb carbon dioxide, have grown wildly. Most vertebrates die, and all pollinators die, resulting in the death of all plants that reproduce by pollen. Due to uncontrolled rainfall, man-made deserts have been turned into jungles and meadows.

The deterioration of the air inside Biosphere 2 directly endangered the health of the inhabitants, and scientists were forced to withdraw from this "Garden of Eden" ahead of scheduleMore carbon dioxide and less oxygen (because there are relatively few plants to convert and release oxygen from as much carbon dioxide produced by people and plants themselves.) Oxygen is consumed at a rate higher than it is produced, while carbon dioxide is produced at a higher rate than consumed), imbalance of the water cycle, imbalance of biological species relationships, etc.

The Biosphere 2 experiment ended in failure.

Scientists call the Earth's biosphere "Biosphere 1". In order to better study the phenomenon of ecological imbalance, the United States spent a huge amount of money in the 80s of the 20th century to build a completely closed experimental base that simulates the earth's biosphere, which is the famous "Biosphere 2".

Location

Biosphere 2 was built in the desert of Arizona, USA. It is a glass building with a steel frame structure of about 1 hectare and several separate ecosystems inside

There is a small ocean, several marshes, lakes, a sandy beach, a rainforest and a meadow.

Biosphere 2 is completely cut off from the outside world, with only sunlight accessible. In this biosphere, plants provide oxygen and nutrients for animals, animals provide carbon dioxide for plants, humans depend on cultivating crops and raising animals for food, and microorganisms in the soil can decompose animal and plant carcasses and excrement. In this way, a relatively stable ecosystem can be formed.

Experiments

In January 1993, eight scientists entered Biosphere 2. According to the plan, they will stay in it for 2 years, while doing scientific research, while living a completely self-sufficient life. In the past 2 years, except for the initial batch of items, everything else has to be obtained by themselves.

They also have to find ways to regulate and control the temperature and climate in the circle.

Results

The results were unsatisfactory, and due to the lack of a firm experimental theory, a series of chemical reactions took place after a year of carbon in the soil, oxygen in the greenhouse, and calcium in building materials. This resulted in a decrease in oxygen content from 21% to 14% in Bio 2.

Due to the lack of internal climate adjustment, the food production was insufficient, and the scientists had to eat food seeds to satisfy their hunger, and finally had to evacuate from the Biological Circle 2. The experiment ended in failure.

Scientists refer to the Earth where humans recuperate as "Biosphere 1". In order to test whether human beings can survive without the earth, the United States began to build an almost sealed "Biosphere 2" experimental base in the desert of Arizona in 1984. The site is a large glass and steel greenhouse, modeled after the Earth's ecosystem.

The laboratory covers an area of 10,000 square meters, with a volume of 10,000 cubic meters, and consists of five parts: a tropical forest with miniature mountains; an ocean with coral reefs and 1 million gallons of water; a desert; a prairie and a marshland; There is also a half-acre of garden land for growing grain and vegetables.

With soil, water, air, and a wide variety of flora, fauna, and microorganisms, scientists hope that the laboratory that mimics the Earth's environment will be able to provide enough food, water, and air.

Biosphere 2 "Since it is man-made nature, is there any human habitation?" The answer is, "Yes!" But this "Biosphere 2" is inhabited not by ordinary people, but by eight scientists;

Of course, scientists do experiments at Biosphere 2, but they also have the participation of plants and animals, which are home to 3,800 species of plants and animals. Since September 26, 1991, eight scientists have officially entered this completely sealed "miniature world". They lived in it for two years before leaving the "giant glass lab" in September 1993.

During this period, they experienced a crisis of reduced oxygen levels in the air, soaring levels of carbon dioxide, increased nitric oxide levels, and other crises that forced them to intervene. Scientists have also found that, with the exception of lianas, which are more luxuriant, all pollen-borne plants have become extinct, and the trees are crumbling. Scientists have also found that most of the insects, with the exception of termites, cockroaches and gnats, are almost all dead.

Creatures in the man-made ocean, the situation is slightly better than on land. Due to uncontrolled rainfall, man-made deserts have turned into meadows.

After the modifications, on March 6, 1994, seven more scientists entered Biosphere 2 for 10 months of experiments. In September 1996, a committee composed of a number of scientists and experts summarized the Biosphere 2 experiment and declared the multi-year Biosphere 2 experiment a complete failure. This study proves that under the current scientific and technological conditions, human beings are not able to maintain the vitality of the earth by artificial methods, and human beings will not be able to survive without the earth.
