On carbon emissions from energy sources
In ancient times, when it comes to energy use, the harm of carbon emissions is not detailed. In today's world, science and technology are advancing day by day, energy is widely used, and the problem of carbon emissions is gradually emerging. Investigating its source is not a matter of detail.

Carbon sources come from the burning of firewood
In ancient times, people used firewood as the main energy source. The trees of the mountains and forests are cut and burned for cooking and heating. However, the burning of firewood, carbon comes out with smoke. Between the countryside, households make fires, and the smoke from cooking is curled. The carbon-containing things are scattered in the sky and the earth. Although the population was not large at that time, it accumulated over the years, and its carbon emissions cannot be ignored.

The use of coal and carbon emissions
and the rise of coal, the field of energy is one of the changes. Coal is stored in the ground, it is convenient to use, and the heat is high, everyone likes it. The factory is powered by coal, the fire is raging, the black smoke is billowing, and the carbon emission is huge. The home is also heated by coal. In the cold winter, coal stoves are all over the market, and carbide fills the streets. When coal is burned, sulfur and carbon are produced together, which is very harmful to the quality of the air and human health.

The situation of carbon emissions from petroleum products
Petroleum is an important energy source in modern times. Refined into gasoline and diesel for transportation. The streets and alleys, the traffic Ma Long, the engine roars, the exhaust gas is thin, all of which are the carbon emitted by the combustion of oil. Ships travel in rivers and seas, and their power depends on oil, so their carbon emissions can also be seen. In the aviation industry, aircraft go through clouds and fog, fuel consumption is huge, and carbon emissions are at high altitudes, which affects climate changes.

Natural gas carbon emissions are briefly described
Natural gas, a cleaner energy source. However, its combustion also produces carbon. In urban and rural areas, pipelines transport gas for cooking and heating. Although carbon emissions are slightly less than coal and oil, the amount of carbon emissions is increasing day by day, and the carbon emissions are increasing, which is also a concern for the climate.

In today's world, knowing the harm of carbon emissions is about energy use, and thinking about changes and seeking innovation. Reducing the dependence of fossil energy and promoting clean energy such as wind energy, light energy, and water energy is a long-term solution, which can slow down climate change, protect the beauty of mountains and rivers, and leave blessings to future generations.
