Air pollution has become increasingly common in modern society. There are several factors that contribute to this. This essay will discuss the main causes as well as possible solutions.
First problem is cars. Many people use cars every day. Cars make smoke and bad gas. This gas makes air dirty. In big cities, there are many cars, so air is very bad. People breathe this air and get sick.Solution for cars is to use public transport. If people use bus, train or metro, there will be less cars on road. Also people can use bicycles. It is good for health and for air. Government can also make electric cars cheaper. Electric cars do not make smoke.Second problem is factories and plants. Factories make many things, but they make a lot of smoke too. This smoke goes to air and makes it dirty. Solution for factories is to use filters. Factories must clean their smoke. Government should make strict rules.
In conclusion, cars and factories are two main causes of air pollution. If we use public transport and clean filters, the air will be better
