But if the environment is polluted, it can bring a lot of terrible problems. Please look at this picture, the sky is gray, billowing smoke is given out into the air. It is bad for people’s health. The river is full of oil stains, which sent off by the factories. Furthermore rubbish heaps are seen everywhere. The polluted environment is bad for the human being and the living.So the whole world must pay attention to the matter of pollution problems. A lot of measures must be taken to control and prevent all kinds of the pollutions. Or else the pollution will get more serious. All of us must realize the importance of preventing the pollution. The earth is our only home so we must make it comfortable for ourselves and for our generations to live on.On PollutionPollution is becoming more and more serious all over the world. Please look at the picture of the real world. First, the poisonous gas sent off by factories and automobiles is filling the air which is unhealthy for people to breathe. Second, waste water keeps pouring into rivers and lakes; as a result, many water species are dying out. Furthermore, hills of rubbish can be found everywhere. We live in a polluted environment, which does great harm to our health.People are showing a real concern over the problem. The public have been calling for firm actions against pollution. Scientists have warned that unless effective measures are taken, pollution will get more serious. Instead, the earth is our only home and we should make it comfortable for ourselves and for our later generations.Fortunately, measures are being taken to do with the situation and nearly all of the countries are trying hard to stop and control pollution, yet progress is slow, and it seems that we have a long way to go before we have a “clean” world. At any rate, we should try our best to fight against pollution, and hold on to the last.
