On man-made carbon dioxide emission sources

The human source of carbon dioxide in the world is related to the climate and ecology of the world, and it cannot be ignored.

Man-made sources are the first to promote energy consumption. In today's world, coal, oil, and natural gas are the main energy sources. People use them for heating, power generation, and driving. When these energy sources are burned, carbon and oxygen are synthesized, resulting in carbon dioxide, which rises in the atmosphere. Like industrial plants and machines, they all rely on energy, and the amount of carbon dioxide emitted by their burning energy is huge. And the cars, or fuel oil, or gas used by people in daily life are also sources of carbon dioxide.

Industrial manufacturing is also an important source. Metallurgy, chemical industry and other industries, the manufacturing process requires high temperature, which relies on energy to burn for heating. And manufactured things, such as cement, are made by the method of calcination of limestone, which also releases carbon dioxide. The carbon dioxide emitted by this industrial manufacturing accounts for a large proportion of human sources.

Agricultural activities are also similar. Farmers are fertile fields and often apply chemical fertilizers. Among them, nitrogen-containing fertilizers are chemically transformed in the soil to produce greenhouse gases such as nitrous oxide. Although they are not carbon dioxide, they will indirectly cause carbon dioxide to increase. In addition, animal husbandry, cattle, sheep and other animals, digested after eating grass, will emit methane and other gases. Methane is chemically transformed in the atmosphere, which will also affect the amount of carbon dioxide.

There are many kinds of man-made carbon dioxide emission sources, and their impact is far-reaching. Everyone should think about reduction strategies, seek new energy, change industrial methods, and improve agricultural policies to slow down the increase in carbon dioxide and protect the world's environment.
