no one，regardless of race, religion or nationality, can deny that the world we live in is becoming increasingly intolerable because of the effects of global warming. according to many experts, even greater impacts are still on the way.
there are numerous causes for this problem. on one hand, human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming according to the theory. on the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem.
it is urgent that immediate and effective actions should be taken right away. first, more trees need to be planted to help improve and beautify the environment. besides, stricter laws concerning global warming and irresponsible use of fuel resources have to be put into effect and achieved good results. in a word, there is a long way to go before we can take a comfortable world for granted again .

many people are active in fighting against unfair treatment to colored people, women , animals and so on. right now i am talking about fighting for respect to our environment.though the environment doesn't have a mouth done to deprecate what humans have done to her, she retaliates through action. in the early years the chinese cut down large quantities of trees, at the source of the yellow river, which led to the disappearance of big forests and terrible floods. as a result, the huangtu plateau which once was once covered with grass and forests was turned into barrens that supported fewer plants. another example was in several developed countries.

because many chemical factories discharged poisonous gas without filtering it, poisonous cities were covered with so much poisonous gas that people were killed by the air they breathed in. what horrible scene!what we are suffering is only a small part of what the nature once suffered. if we don't take action to show respect to the environment, we will have to face an increasingly awful situation. measures should be taken to protect the environment on which we are relying. first governments should forbid destroying vegetation, rivers and lakes, oceans, as and the atmosphere as well. second voices should be made to announce the public of the importance of protecting the environment. third enterprises should pay special attention to the effect they have on the environment and work out solutions for the problems. only by changing the way we treat the environment can along we get along well with it.【1】 【2】
