In today's world, the largest source of carbon dioxide in the atmosphere is related to the livelihood of everyone and the change of heaven and earth. To investigate its source, the first is to burn fossil fuels, such as coal, oil and natural gas. People rely on the burning of these fuels for their daily livelihood, for heating, power supply, and driving boats.

Every time a stone of coal is burned, or a barrel of oil, or a side of natural gas is burned, a large amount of carbon dioxide is released into the atmosphere. Although such combustion is of great benefit to the rise of industry and the smooth transportation, it also causes the amount of carbon dioxide in the atmosphere to rise sharply.

And the cutting of forests is also the reason for the huge increase in carbon dioxide. Forests, the giants of carbon sequestration, can absorb carbon dioxide and release oxygen. However, due to the reclamation of fields, wood extraction, etc., people cut down forests widely, causing the carbon sequestration energy of forests to drop sharply, and carbon dioxide could not be absorbed and accumulated in the atmosphere.

Furthermore, farming and animal husbandry are also involved. The respiration of animals and the decomposition of manure all produce carbon dioxide. In addition, the application of fertilizers also promotes the release of carbon in the soil and increases it in the atmosphere.

These various reasons increase the carbon dioxide in the atmosphere day by day, causing the greenhouse effect to intensify, and the climate to change. To solve this dilemma, it is necessary to save energy, promote green energy, protect forests and increase plants, and optimize agriculture and animal husbandry. In order to slow down the accumulation of carbon dioxide and maintain the peace of the world.
