Types of Pollution and Their Sources
Air Pollution
Air pollution is one-way pollution affects animals. It is formed by byproducts of operations that make chemicals airborne. Close to the surface of the earth, sulfur dioxide (SO2) connects with the water cycle to produce acid rain or any other form of acid deposition. Nitrogen dioxide, an emission from vehicles and sunlight, combines with photochemical smog.
In the upper atmosphere, chlorofluorocarbons and other chemical compounds lead to the degradation of the earth’s ozone layer. The major pollutants in the air include burning fossil fuels, automobiles, agricultural activities, factories, mining activities, and other sources of domestic waste. Air pollution leads to several health hazards for animals in many ways.
The effects of pollution on animals, especially air pollution, are almost the same as those on humans. Like humans, animals suffer from breathing problems, skin diseases, etc.
