The carbon cycle in nature

It's no secret that the carbon cycle in nature determines the conditions of life on the planet Earth. The balance of this element for many millions of years formed naturally in the atmosphere, the earth's surface and living organisms. First, the annual carbon balance in the atmosphere is determined by the difference in the amount of carbon dioxide spent by the atmosphere on the "construction" of the green mass, and its amount, which was released to the atmosphere during the decomposition of organic substances. Secondly, the mass of plants should grow with increasing carbon concentration in the atmosphere and with increasing its temperature. Finally, the intensity of the decomposition of organic matter on earth also increases in proportion to the temperature of the atmosphere, and the temperature itself is related to the carbon content - the so-called "greenhouse" effect.

The carbon cycle in nature was disrupted when a person began to burn the organic matter accumulated in the depths of the Earth - coal, oil, natural gas

The carbon cycle in nature was disrupted when a person began to burn the organic matter accumulated in the depths of the Earth - coal, oil, natural gas. Therefore, the content of carbon dioxide in the atmosphere began to grow... Will this lead to irreversible and undesirable changes in the Earth's climate, and to what extent can our planet compensate for human interference in the natural carbon cycle in nature?

To answer these questions, scientists have created a mathematical model that best describes the cycle of carbon in nature. After entering it into the computer, the model spoke in a clear language of thought-provoking numbers. Today, only 46% of the carbon dioxide produced by humans can be included in nature in their carbon cycle. And most of it is absorbed by the plant world, the smaller part is taken by the World Ocean. This clearly proves the primacy of the atmosphere, plants and soil in neutralizing excess carbon in nature.

The model also provided a forward-looking forecast. Taking into account the current rates of absorption by the atmosphere, plants and soil of carbon dioxide emitted into the atmosphere, its content over 20 years will grow by approximately 25%. As a result, the atmosphere becomes warmer by 0,39-0,450 C.

How can we weaken the influence of such warming? For example, if the temperature of the atmosphere increases, the conditions for the flow of biological processes on Earth will be more favorable. This will lead to more intensive development of vegetation, and hence, to greater absorption of carbon dioxide. The chain of interactions is naturally closed by a decrease in temperature in the atmosphere.

This is how, according to the "answers" of the model, the carbon cycle in nature must self-regulate. But this does not mean that you can rely entirely on nature: its natural abilities are limited. How then can nature be helped?

The answer to this question is quite simple: conservation of forests. Compared to the grass cover, the forest is a much more powerful instrument for compensating for thermal effects, absorbing a significant part of the surplus of the "warming" atmosphere of carbon dioxide. Hence the most immediate practical conclusion: the expansion of agricultural land through deforestation leads to a weakening of the possibilities of nature in the carbon cycle. This council of biosphere health should become a guide to action!
