I want to talk about Causes of Air Pollution. The first cause I want to mention is emissions from factories and vehicles. Since emissions from factories are not treated, they are very harmful to both the air and the environment. One of the substances that contribute to air pollution in these gases is carbon dioxide (CO2), which is also present in exhaust from vehicles. In addition, today, more and more factories and vehicles appear, making air pollution more serious. The more gases are released into the air, the more polluted the air becomes. And this brings some bad effects to both the environment and people. Now, I will continue with the second part on the effects of air pollution. Firstly, polluted air definitely affects the environment. Air pollution means high levels of CO2 in the atmosphere, and this gas causes the greenhouse effect. This phenomenon will lead to global warming and this is very bad for the environment. In addition, the ecosystem is also affected because in places where there is more CO2 than oxygen, it is difficult for organisms to survive. They may die or become extinct. Another effect is that air pollution harms human life. Air pollution damages human health because it causes respiratory diseases. Besides, it can have a negative effect on daily life. When the air is seriously polluted, people will want to stay at home rather than go out to avoid illness, and this disrupts their daily lives. Furthermore, pollution also costs the government to deal with the problems it causes. Every year, the government needs to spend a large amount of money to deal with the problem of air pollution for a better society. If not prevented as soon as possible, the amount will gradually increase.
