If carbon dioxide gas is produced in excess, it will accumulate in the atmosphere, causing the global climate to have an unpleasant greenhouse effect. In places covered by green vegetation, especially in forests, through photosynthesis, green plants absorb carbon dioxide in the air and release it. Oxygen. 
As long as the plant-generated fuel consumed by factories in various countries is controlled within a certain limit, the greenhouse effect of the global climate can be avoided.
 in this sense, the destruction of green vegetation, especially forests, means the production of carbon dioxide. The consumption of fuel generated by plants by factories produces a large amount of carbon dioxide gas, which includes wood, coal and oil.
