Pollution

I think there are many reasons for pollution, such as car exhaust emissions, factory exhaust emissions, garbage littering and so on. Pollution will lead to many problems and influences, such as causing people to have diseases, making the air worse, polluting the environment and so on.I think if we want to solve the problem of environmental pollution, we should start from everyone. We can plant more trees, try not to use plastic bags, drive less and take more buses.

This picture is about pollution. The exhaust emissions from cars may cause pollution. There are many cars in this picture. The more cars there are, the more exhaust emissions there are, so the air pollution is more serious.
This picture is the specific picture of automobile exhaust emissions, as we can see, this picture of exhaust emissions is very large, and can smell a very bad smell, a lot of pollution to the air.
