The carbon source of the United States
The carbon source of the United States involves a wide range. One is the energy field. In the production of electricity in the United States, coal and natural gas still account for a considerable proportion of power generation. When coal is burned, a large amount of carbon escapes from the air, which is an important carbon source. Although natural gas is cleaner, it also releases carbon when burned.

In the industrial field, many industries are carbon sources. In iron and steel smelting, the ore reduction process requires coke, and coke combustion causes carbon emissions. In chemical production, raw material conversion and reaction steps, carbides decompose and oxidize, and carbon is also released into the atmosphere.

In the transportation field, it can be called a major carbon emitter. In highway traffic, there are huge numbers of cars, fuel vehicles are driven every day, and fuel combustion is a continuous carbon source. Air transportation is also not to be underestimated. Aircraft fuel consumption is large, and carbon emissions are emitted at high altitudes, which affects the global carbon cycle.

In agriculture, although it is not an intuitive carbon source, it is actually closely related. Livestock breeding, cattle and other ruminants produce methane during digestion, which has a greenhouse effect greater than carbon dioxide. Farmland soil management, such as unreasonable fertilization, can cause changes in soil microbial activities and affect carbon release and storage.

Beauty's carbon sources are diverse and complex. To reduce carbon emissions, it is necessary to coordinate in various fields to effectively address the challenge of climate change.
