On the source and destination of the carbon cycle process
Between heaven and earth, the cycle of carbon is related to the life of all things. Its source and sink are fixed, and various processes complement each other.
The source of carbon has many sources. First, biological respiration is a common source. All creatures, no matter how big or small, need to breathe to survive. Inhaling oxygen and exhaling carbon dioxide, this is the path of carbon into the atmosphere. Second, the burning of fossil fuels is also an important source. Coal, oil, and natural gas have been buried deep over the years, and once burned, a large amount of carbon was released into the air as carbon dioxide. Furthermore, forest fires broke out, the trees were burned, and the carbon also escaped with the fireworks.
As for the fate of carbon, there are also many paths. Oceans are a great sink of carbon. Seawater contains soluble carbon dioxide, some of which are chemically reacted into carbonates and sink to the bottom of the sea. There are also marine organisms that use photosynthesis to fix carbon in their bodies and settle after death, adding to the carbon storage in the ocean. Forest vegetation is also a reservoir of carbon. Green plants photosynthesize, absorb carbon dioxide, and store carbon in branches, leaves, and roots. In the land, organic matter decomposes and humus forms, which is also the destination of carbon. Part of the carbon is retained in the soil and participates in the soil carbon cycle.
Looking at the whole process of the carbon cycle, the source and destination are balanced with each other, and the ecology is safe. If the source is too abundant, such as excessive burning of fossil fuels, carbon emissions will far exceed the absorption capacity of the destination, and the carbon concentration in the atmosphere will rise, causing global warming and frequent disasters. Therefore, when the source is recycled, the balance of the carbon cycle should be maintained, and the ecological peace of heaven and earth should be maintained.
