On oil and coal as the source of carbon dioxide
It is well known that oil and coal are the most commonly used energy sources in the world. However, few people have studied their relationship with carbon dioxide in detail. Let's try to explain the important sources of carbon dioxide between oil and coal.

Oil is buried deep in the ground and has undergone hundreds of millions of years of biochemical changes. It is formed from the remains of ancient organisms, which have undergone many geological processes, and gradually transformed into a thick mixture of liquid hydrocarbons. The formation of coal also originated from plants in the past, which have undergone crustal changes and deep carbonization, and finally became solid fuels.

When oil and coal are mined and burned for energy, major chemical changes are triggered. The two are rich in carbon. During the combustion process, carbon and oxygen in the air undergo a violent chemical reaction. The reaction formula is roughly: carbon (C) and oxygen (O 2) combine to form carbon dioxide (CO 2). During this process, the carbon in oil and coal is released into the atmosphere in large quantities in the form of carbon dioxide.

Looking at today's industries, whether thermal power generation, factory operation, or transportation, they all consume a lot of oil and coal. Thermal power generation is mostly fueled by coal. During the raging fire, carbon is rapidly converted into carbon dioxide, and thick smoke billows into the sky. In transportation, automobiles, airplanes and other petroleum products such as gasoline and aviation kerosene, etc., the engine starts, the fuel burns, and carbon dioxide is constantly emitted. Factory production requires energy to drive many processes, and the combustion of oil and coal is also an important source of carbon dioxide.

For a long time, due to the large-scale combustion of oil and coal, the content of carbon dioxide in the atmosphere has increased. This not only causes the severe situation of global warming, but also causes many evil consequences such as glacier melting, sea level rise, and abnormal climate. It also affects the ecological balance and endangers all living things.

Therefore, oil and coal are undoubtedly the main sources of carbon dioxide. In order to protect the ecological environment of the earth, human beings should find good strategies to reduce the dependence on oil and coal, and find clean energy to replace them, so as to slow down the emission of carbon dioxide and protect the tranquility of the world.
