On the Three Sources of Carbon Dioxide
Between heaven and earth, there are three sources of carbon dioxide. One is the breathing of living things. All kinds of creatures, animals and plants are the same, and they usually absorb and spit out turbid. Animals live and breathe during the day and night, and they all rely on the opening of their lungs. They exhale breath and exhale carbon dioxide. Although plants are different from animals, they also have the function of respiration. In the dark night, they absorb oxygen and expel this gas. This is often a source of carbon dioxide.

The second is the combustion of fuel. Since the flutters drilled wood for fire, humans have used fire for a long time. Firewood, coal, and oil and gas are all commonly used fuels. When these things burn, they combine with oxygen to produce carbon dioxide. Between the wells of Guanfu City, cooking smoke curls; above the passageway, vehicles are galloping and exhaust gas is emptied; in the factory, fires are burning, all of which are used for combustion, and carbon dioxide is also produced. This fuel combustion is also a major source of carbon dioxide.

The third is the activity of the earth's crust. Mountains and rivers and the earth are not constant. When a volcano erupts, the ground is hot and the magma is surging, and a large amount of carbon dioxide is ejected with hot air and volcanic ash, permeating the sky and the earth. And deep in the stratum, carbonaceous minerals under high temperature and pressure will also decompose to produce carbon dioxide, or slowly escape through the cracks in the ground. Those born of this crustal activity are another source of carbon dioxide.

Knowing these three sources, you can get it from the generation of carbon dioxide. Seeking a clear environment and a stable climate is a long-term solution when it comes to the three sources.
