Analysis of Carbon Sinks of Grasses and Trees
On the role of plants and trees in carbon, either as a source or as a sink, there are various opinions.

Considering the actual situation, when plants and trees grow, they use photosynthesis magic to absorb carbon dioxide in the air, combine water and light and heat, make organic quality, and sequester carbon. At this time, the amount of carbon absorbed by them is more than released, which is like a carbon sink. Looking at the forests, vast and continuous, green trees, year after year, countless carbon sequestration, which is great for slowing global warming.

Of course, there are times when plants and trees are also sources of carbon. In case of natural disasters, fire burns the forests and fields, flames soar, and plants and trees burn quickly, and the sequestered carbon quickly returns to the atmosphere and becomes a source in an instant. Another example is that grass and trees wither, rot on the ground, and decompose by microorganisms, and carbon gradually escapes in the form of carbon dioxide. Under the circumstances, man-made logging of forests to make fields, destruction of wood to build cities, causes the grass and trees to decrease sharply, its carbon sequestration power declines, and the potential of carbon sources increases.

To sum up, the study of grass and trees as carbon sources or carbon sinks cannot be generalized, depending on the growth situation, external conditions and human measures. In order to protect the carbon sink of grass and trees, it is necessary to protect forests and forests, prevent fire pests, and control man-made destruction, so that they can play a permanent role in the carbon sequestration industry, maintain ecological balance, and protect the safety of the earth.
