Looking at the various species in the world, people are in the middle of it, and in the circulation of carbon, the implications are not light. And the husband's daily living and travel are all related to the metabolism of carbon.

People's diet, farming and animal husbandry, among which agriculture, carbon emissions are involved. The fields, the application of manure, and the rot of crops all release carbon into the atmosphere. Livestock, the respiration of livestock, and the decomposition of excreta are also one of the sources of carbon.

As for housing and transportation, cars are on the road, and fuel is driven, and carbon emissions are endless. Building construction and building materials are fired, which can consume a lot of carbon and overflow carbon. Daily electricity, thermal power is the main one, coal is burned to generate carbon, which is lost in the four directions, and people use it, all with traces of carbon.

However, people can also be carbon sinks. The act of afforestation, trees absorb carbon to make a living, the photosynthesis of leaves, and the sequestration of carbon in the body form the basis of carbon sinks. Furthermore, with the increasing development of science and technology, carbon capture and sequestration techniques are gradually emerging, and industrial exhaust gas, which is used to keep carbon in the ground, can also be the path of artificial carbon sinks.

Therefore, people are in carbon, which is both a source and a sink. The source, living and production, the dissipation of carbon; the sink, the assistance of forest planting technology, the accumulation of carbon. Desiring for the balance of carbon, people should be aware of the two, save resources and increase remittances, in order to achieve long-term peace.
