There is a question about the proportion of carbon dioxide sources today. Examine in detail, in order to clarify the proportion of various types of carbon dioxide in the total.

Looking at the actions of industry, its production, or the production of large amounts of carbon dioxide, the proportion is probably not small. The operation of factories, the operation of equipment, and the combustion of fuel are all sources of carbon dioxide, and their proportion may reach 50%. Because of its large scale of production, it can be used a lot.

Furthermore, in the field of transportation, vehicles are constantly flowing. Whether it is cars, trains, planes, or ships, when fuel is driven, carbon dioxide also escapes. Take today's common motor vehicles as an example, there are many in cities, and their carbon dioxide emissions account for more than 20% of the total. Because it is an essential tool for daily travel and cargo transportation, it is used frequently and consumes a lot of energy.

As for the lives of residents, it should not be underestimated. Cooking and heating in the home also produce carbon dioxide. Although the amount used by each household may be limited, it accounts for 10% and a half of the population. This is due to the large number of people and the continuous consumption of energy required for daily life.

In addition, agricultural activities are also one of the sources of carbon dioxide. In farmland, crop respiration and soil microbial activities all release carbon dioxide. However, compared with the previous ones, it accounts for about 10%. The nature of agricultural production is different. Although it is widely distributed, the emission per unit area is relatively small.

Overall, industry, transportation, residential life, agriculture, etc. are the main sources of carbon dioxide, each accounting for its own proportion. To reduce the amount of carbon dioxide, it is necessary to take good measures in all aspects.
