The outline of the source and sink of the carbon cycle
Between heaven and earth, the cycle of carbon is related to the survival of all things, and the reasons are complicated. Here is the key to its source and sink to clarify its importance.

Carbon sources, carbon is released in the atmosphere. First, the burning of plants and trees, the raging fire, the destruction of forests and the opening of the wasteland, the lush forests in the past are completely absent, and a large amount of carbon escapes. In ancient times, deforestation was destroyed, and the smoke and flames spread into the sky. Carbon also rose into the air with the smoke, causing the atmospheric carbon to increase. Second, the burning of mineral fuels, coal, oil, and gas, have been buried deep over the years, and are now used by people. They are burned in stoves and cars, and their carbon is turned into gas into the air. Since the industrial boom, machines roar, fuel consumption has increased sharply, and carbon sources have become more and more extensive. Third, living things breathe, and both humans and animals are like this. Between the old and the new, carbon dioxide is exhaled, which is also one of the carbon sources. Although a single individual has limited emissions, but all living beings multiply, the number is huge, and its accumulation is also huge.

Carbon sinks are also places where carbon is collected and stored. Forests are the first, with lush trees and lush green leaves. Photosynthesis occurs, carbon is absorbed in gas, and stored in branches and roots. In the land of lush forests, carbon sinks are quite abundant, so the ancient deep forests and dense green forests are all carbon reservoirs. Second, the ocean is vast, and there are many plankton, which absorb carbon to make a living, and seawater also dissolves carbon dioxide. The ocean is vast, and the amount of carbon it contains is innumerable. Furthermore, in the soil, microorganisms are active and participate in the transformation of carbon, and humus and other carbon-containing substances are also forms of carbon storage.

It is clear that the source and sink of the carbon cycle are important, and a balance should be sought. Reduce carbon sources, control the use of mineral combustion, advocate clean energy, such as sunlight and wind; protect forests and cultivate forests, and prohibit indiscriminate logging. Increase carbon sinks, plant trees widely, and promote afforestation; maintain marine ecology and maintain soil health. In this way, the carbon cycle is orderly, the ecology can be balanced, and all things can live in peace.
