求一篇英语作文,fight against air pollution
Air pollution has become a serious problem in recent years.There are a lot of causes.first of all,is the chemical noxious gases emission.We all know that there are a lot of of factories around the world,they are actually emitting such gases everyday.The second one is the sharp decrease of the forests.Forest is very important to our Eco-system,it can adjust the heat and balance the air.The third one is the urbanization.People tend to stay in the city where is actually an abnormal Eco-system.Many cities do not have a complete system of controlling the air pollution.
In order to solve such problems,I have some ideas.
First of all is to control the emission of noxious gases.A set of necessary standards is required.It is not allowed to emit some particular gases until they have been transferred to another kind of chemical substance that is harmless to environment.Second one is planting more trees.We have cut down a lot of trees.It does have side effect on the quality of air.By planting more trees,many environment problems can be solved rather than air pollution only.

One of the most serious problems man is facing is pollution. The poisonous waste may do harm to the things around us. The air pollution can bring death to some people and kill trees and vegetables. Very loud noise can make people ill, hurt their ears or even drive them mad. So we have to realize the harm done to man by pollution. We must try our best to fight against pollution. I’m sure some day we’ll win the battle.第二个
Pollution is harmful to human beings. Polluted water causes many kinds of diseases such as diarrhea, enteritis, etc. And sometimes these diseases even take man’s life. Dirty air or air-borne garbage causes stinging eyes and running nose. Pollutants are destructive. They cause runs in nylon stockings and crack rubber tires and they eat away at stone and rust iron.
Measures have been taken to control pollution. In recent years, legislative steps have been introduced to control pollution. Rivers are being cleaned. Air is purified, and pollutants are being trapped before they are poured out of chimneys.
However, pollution problems have not been completely solved. Pesticides are widely used almost everywhere. They pollute soil, water and food. They have the power to make our streams fishless and our gardens and woodlands silent and birdless. Some factories are still using air as a dumping place for wastes. Some lakes are still dirty. Quite a few chimneys are still pouring smoke into air and noise pollution remains serious.

Wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air. If there are impurities in the air, they may be absorbed by our bodies and make us ill. We need clean air, but unfortunately, air pollution is globally present, especially in cities. Many large cities are anything but pollution-free. Our cities have many factories, which we need to make food, clothing and other things. Every year these factories pour millions upon millions of tons of smog into air. Power plants and houses that burn coal add greatly to air pollution. Besides, there are more cars in cities now. Once out on the streets, they will take in fresh air and replace it with poisonous gases. Our country is trying hard to prevent and control air pollution. As long as every citizen also realizes its importance and makes join efforts, the day will come soon when people will take in only clean air. Then, the sunlight will no
