Analysis of global carbon emission sources
In recent times, the world wind has changed day by day, and the global climate has also changed. The main reason is that the sharp increase in carbon emissions is the key. Only by analyzing the sources of global carbon emissions in detail can we get the gist and find feasible solutions to eliminate this big problem.

The first to bear the brunt, the use of energy is the bulk of carbon emissions. Fossil energy sources such as coal, oil and natural gas are still dominant in the energy pattern of today's world. Since the dawn of industry, there are many factories, machines are roaring, and fossil energy is the source of power. When this generation burns, carbon combines with oxygen, and a large amount of carbon dioxide escapes into the atmosphere. Looking at electricity production, coal-fired power stations still generate a considerable proportion of electricity, and their daily emissions of carbon dioxide are huge. And in the field of transportation, automobiles, ships, airplanes and other means of transportation, most of which use petroleum products as fuel, shuttle between, exhaust emissions continue, adding a lot of carbon to the atmosphere.

Second, the process of industrial production is also an important source of carbon emissions. Metallurgical industries, such as iron and steel smelting, consume a lot of energy in the process of ore reduction, and the carbon contained in the ore is also released at high temperatures. In the chemical industry, from the preparation of basic raw materials to the synthesis of various fine chemicals, many reaction steps are associated with carbon emissions. Cement manufacturing is particularly prominent. The process of calcining limestone to generate cement clinker, the decomposition of calcium carbonate produces a large amount of carbon dioxide, and the global cement production remains high. The carbon emissions of this industry should not be underestimated.

Furthermore, although agricultural activities are the foundation of people's livelihood, they are also closely related to carbon emissions. In rice fields, due to water flooding, the soil is in an anaerobic environment, and microorganisms decompose organic matter to produce methane, which is a powerful greenhouse gas, and its warming effect is several times that of carbon dioxide. And livestock breeding, cattle, sheep and other ruminants, because of their special digestive systems, belch out a large amount of methane during digestion. At the same time, in agricultural production, nitrogen fertilizer is applied, and part of the nitrogen is converted into nitrous oxide by microorganisms, which has a considerable greenhouse effect.

At the end, land-use change and forestry activities also have a significant impact on carbon emissions. Deforestation and degradation have greatly reduced the area of forests that were originally used as carbon sinks. Trees absorb carbon dioxide and store it in xylem and soil, and forests are deforested, and the stored carbon is re-released into the atmosphere. Urban expansion, infrastructure building, etc., a large amount of land is converted from natural state to artificial land, ecosystems are changed, the carbon cycle is unbalanced, and carbon emissions increase.

In summary, the global carbon emission sources are complex, and energy use, industrial production, agricultural activities, and land use change are all important factors. In order to reduce the trend of global warming and control carbon emissions, it is necessary for all parties to cooperate, introduce new ideas in various fields, find clean alternative energy sources, improve industrial production processes, optimize agricultural production models, and protect forest resources, so as to hope to reshape the ecological balance of the earth.
