Air pollution is a serious problem in our country. Causes such as: Wind dust, storms, tornadoes are the main factors that increase the scope of air pollution on a large scale because most of the dust and emissions are carried away by the wind, and forest fires are the main causes. The cause of the increase in the amount of nitrogen oxide gas in the air every year is because the scale of the fires is usually large and takes a lot of time to extinguish in which a large amount of gas will rise, in which, sulfur dioxide gas accounts for quite a lot and this This is the cause of air pollution, even acid rain. There is also the phenomenon of thermal incompatibility, a phenomenon that often occurs around the time of season change and it creates a low-level smog layer that causes pollutants. in the air is trapped in the atmosphere close to the ground and causes air pollution. In addition, radioactive substances, ocean waves, decomposition of dead plants and animals, etc. are also natural activities that cause air pollution. And because it is an objective factor, it is difficult for humans to prevent and eliminate them.
