Between heaven and earth, carbon is in the atmosphere, and its sources are various. Linze is lush, between tona, carbon enters the gas, which is one of its sources. Forest trees are prosperous, when photosynthesis, they absorb carbon and release oxygen, but they wither and decay, and carbon also returns to the atmosphere.

There is also the burning of ground fire, coal seams, oil reservoirs, and burn in case of fire. With a raging trend, carbon rises with the flames, and it is the second source of carbon in the atmosphere. Ancient deposits have deep carbon deposits. Once burned, the amount of carbon is huge.

In addition, the breath of sentient beings, such as humans and animals, breathes and tona, and also releases carbon gas. Day and night, the cycle is endless, although the amount is small, the accumulation is also one of the carbon sources in the atmosphere.

Therefore, the carbon in the atmosphere comes from many sources, which is related to the rise and fall of forests, the intensity of fire, and the breath of all living beings. It is necessary to investigate it carefully to understand its changes and seek ecological balance.
