"On the Multiple Sources of Carbon Dioxide Entering the Atmosphere"

Between heaven and earth, carbon dioxide enters the atmosphere, and its source is not the same. In the world, the operation of all things is related to this.

First, the genus of fuel, such as firewood, coal, and oil and gas, when burned, the carbon and oxygen stored in it generate carbon dioxide, which rises in the atmosphere. In ancient times, cooking was fueled by firewood, and the smoke rose from the fire, and carbon dioxide also escaped. Today, the industrial boom, the burning of coal and fuel, the scale is huge, and the amount of carbon dioxide emitted is far more than in the past. Factory chimneys are lined with black smoke, which is also the source of carbon dioxide.

Second, living beings breathe. Humans and animals, etc., are born to need oxygen, absorb clear and turbid, and what they spit out is carbon dioxide. The beasts run in the wild, and everyone goes to and fro in the world, and carbon dioxide comes out with one breath and one breath. And the beasts of the mountains and forests, the fish of the rivers, are all the same. Although the individual is limited, the number of all things adds up, and it is also one of the sources of carbon dioxide in the atmosphere.

Third, between the land, organic matter decays. Fallen leaves and weeds, carcasses and beast carcasses, left in the soil for a long time, decomposed by microorganisms, in which carbon gradually turns into carbon dioxide and rises into the atmosphere. Straw in the fields and rotten wood in the forest all follow this path.

There is also an ocean, and seawater contains carbonic acid, which communicates with the atmosphere. Changes in temperature and pressure cause carbon dioxide in seawater to dissolve or escape. Escaping when warm and dissolving when cold, it is also a variable source of atmospheric carbon dioxide.

All these numbers are the way carbon dioxide enters the atmosphere. The confluence of various sources causes the amount of carbon dioxide in the atmosphere to change from time to time, which is related to the climate of heaven and earth and the life of all things, and cannot be ignored.
