All living things cannot be separated from water. The annual rainfall determines the distribution of terrestrial organisms; it affects the structure, growth and habit characteristics of organisms. Drought leaves wither and growth is hindered; too much water in the soil causes the air to decrease, affecting the respiration of the plant roots, and in severe cases, it will suffocate and die. For animals, lack of water has more serious consequences than lack of food. In arid desert areas, only a few drought-tolerant animals and plants can survive; in tropical rain forest areas with abundant rainfall, the forests are dense and there are many animal and plant species.

Due to the strong attraction of the earth, 80% of the air is concentrated in an area of an average of 15 kilometers from the ground. This air layer has a great impact on human life and production activities. Air pollution is commonly referred to as air pollution within this range. The development of industry has discharged harmful substances into the air, polluted the air, and increased harmful components in the air. When the harmful substances in the air reach a certain concentration, it will seriously harm human health and the growth of crops, destroy certain substances, and reduce human visibility, affect traffic safety, and so on. Therefore, great efforts must be made to prevent air pollution.

The harmful substances released into the air can be divided into the following categories: dust (such as carbon particles), metal dust (such as iron, aluminum, etc.), wet mist (such as oil mist, acid mist, etc.), harmful gases (Such as carbon monoxide, hydrogen sulfide, nitrogen oxides, etc.). From a worldwide perspective, sulfur dioxide and carbon monoxide are harmful and harmful gases with large emissions and great harm. Sulfur dioxide is produced during the combustion of coal and petroleum. Carbon monoxide is mainly emitted when the car is running. It is estimated globally that carbon monoxide emissions exceed sulfur dioxide emissions.
