The following is a classical Chinese article focusing on "American Carbon Footprint By Source" and taking "American Carbon Footprint Sources" as the direction:

In today's world, the reason for the beautiful carbon trace is related to the ecology of heaven and earth, and it cannot be ignored. Its carbon trace comes from various ends.

The first is the daily needs of its people. The transportation is to travel by car. The crowd of cars consumes fuel and emits huge amounts of carbon. All kinds of power depend on the burning of fossils. If coal, oil, and gas are burned, carbon is generated and scattered between heaven and earth.

Furthermore, the prosperity of public works. The factories are numerous, the equipment is running, day and night. The energy it relies on is mostly carbon sources. Refining and smelting, weaving, all rely on carbon power, and carbon is also released with the work, causing the amount of carbon in the atmosphere to increase day by day.

And the supply of housing. The heating, lighting of houses, and the use of energy are also the reasons for carbon production. Warm in winter, cool in summer, equipment operation, the source of carbon consumption is endless.

The service of agriculture and forestry also involves the growth and decline of carbon. The cultivation of acres, the application of fertilizers, and the raising of livestock all have carbon emissions.

The sources of beautiful carbon footprints are intertwined and complicated, affecting the whole body. To reduce the amount of carbon, we should start from various sources, promote clean energy, and change the old methods in order to slow down the trend of carbon accumulation and protect the peace of heaven and earth.
