"On the Main Sources of Carbon Dioxide"

Between heaven and earth, the change of gas affects all things. Now I want to discuss the main sources of carbon dioxide to study the mystery of nature.

One of them is all kinds of burning things. Firewood is burned in the stove, fireworks rise and carbon dioxide is produced. In the past, people used firewood for cooking, and they burned it in the room, and carbon dioxide accumulated in the room. In later generations, the burning of mineral charcoal was even more prosperous. Mineral charcoal was buried in the ground for a long time, dug out, and burned in the furnace. Its fire was raging, and a large amount of carbon dioxide escaped. And the fuel car, running in the road, and the fuel explosion in the engine, is also the source of carbon dioxide. This is all because when burning, carbon and oxygen are synthesized into carbon dioxide.

Second, the breathing of living things. All creatures in the world, from large beasts to small insects and ants, need to breathe in order to survive. Inhaling oxygen and exhaling carbon dioxide is the common way of life. In the mountains and forests, all beasts run around, birds and insects sing and fly, and carbon dioxide comes out of their breaths. Farming in the fields is silent, but the breathing of leaves also emits carbon dioxide. In the case of rivers, lakes and seas, and aquatic spirits, the same is true.

Third, the movement of the earth and the change of mountains and rivers are also the sources of carbon dioxide. Volcanoes erupt, flames take off, magma overflows, and carbon dioxide gushes out with heat, filling the air. In a geothermal place, hot steam evaporates, which also contains carbon dioxide. Within the earth, there are various chemical changes, and carbides decompose when heated, resulting in carbon dioxide.

In summary, combustion, biological respiration, and earth changes are all the main sources of carbon dioxide. Knowing its source, you can think of ways to control it, so as to keep the sky and earth clear and all things peaceful.
