Anthropogenic Atmospheric Carbon Dioxide Theory
In today's world, the change of carbon dioxide in the atmosphere is related to the global climate and has attracted the attention of all eyes. Its sources are numerous, and man-made sources have a great impact.

The rise of industry, the burning of coal, oil and gas, is the main way. Factories are numerous, machines are roaring, and when fuel burns, carbon and oxygen are phased, and carbon dioxide escape into the atmosphere. Blast furnace ironmaking, coke is the source, and in the raging fire, carbon is released into gas and flows into the dome. Electricity production, thermal power accounts for Judah, coal-fired power generation, and carbon dioxide is also produced in large quantities.

The field of transportation, cars, trains, planes, and ships all rely on fossil fuels. Cars shuttle through streets and alleys, with thin exhaust; planes soar in the sky, exhaust gas is emptied; ships break waves in rivers and seas, and black smoke billows. The product of fuel combustion, carbon dioxide is the most important, year by year, its amount increases, causing gradual changes in atmospheric composition.

The state of agriculture is also involved. Fertilizer application, although it promotes crop growth, decomposes nitrogen fertilizer, and part of the nitrogen is turned into carbon dioxide. And when farming, the soil is turned over, microorganisms are active, and organic matter decomposes, and carbon dioxide is also emitted. Animal husbandry, cattle and sheep and other ruminants, when digesting, exhale, mostly containing carbon dioxide.

Building construction, from the preparation of building materials to the completion of buildings, all emit carbon dioxide. Cement manufacturing, limestone calcination, large amounts of carbon dioxide precipitation. Construction, machinery operation, fuel consumption, are also sources of emissions.

In summary, human sources are increasing atmospheric carbon dioxide. It changes in climate, causing global warming, glacier melting, sea level rise, and frequent extreme weather. In order to maintain climate stability, ecological balance, and control carbon dioxide emissions from human sources, it is urgent to take global efforts to find good measures to maintain the safety of the earth.
