Second, the consumption of air pollutants, food and water will be poisoned! Third, the respiratory tract, after the air pollution, will suffer from a variety of serious diseases. From the following examples, we can see that all kinds of air pollutants are harmful to human health through a variety of ways. The impact on the human body is multifaceted.
As the beginning of human environmental protection activities, Earth Day has strongly promoted the formulation of environmental protection and laws in many countries in the world.

Air pollution endangers the survival and development of organisms. There are three kinds of harm, it is possible! One is to dry up the reading in living things and lead to death. The second is to slow down the normal development of organisms. The third is to reduce the resistance of organisms to diseases and insect pests. During the growing period, plants are exposed to air pollution for a long time, which weakens photosynthesis and damages the internal structure. It's the plants that wither until they die. Among all kinds of harmful gases, sulfur dioxide, ammonia gas and hydrogen fluoride are the most harmful to plants.
Air pollution, damage to animals, mainly respiratory tract infections and eating food contaminated by the air! Among them, arsenic, fluorine, lead and molybdenum are the most harmful.
