In the 21st century, human's science economic development has reached a very high level. But I want to ask: do you have any aware of human activities on the environment will be what kind of impact?

　　The deforestation of the forest is not a serious problem? According to the survey the world forest area is in at an annual rate of millions of hectares of disappear. Caused a lot of water and soil loss, make many areas become desert. Scope of human activities in the declining, it's not scary?

　　What human besides destroying forests, don't damage the environment problems? It is not. Now, we should see the seriousness of water pollution. At present, 60% of the country in the world face the shortage of water, 20% of the population is difficult to get clean water, 51% of the people do not have access to sanitary water. This is caused by what? Is, that we are causing ourselves now factories and sewage in our life, not by processing is out. This is not proof of that? According to research, each 1 cubic meter of sewage discharge, 14 cubic meters of natural water pollution. Think of it, this is what a terrible number?

　　In the discharge of smoke in the factory, we don't know the smoke is atmospheric pollution? Scientists have found that there are at least 100 species of air pollutants produced great harm to the environment, directly affect people's health.

　　Do we want to live in such an environment? Certainly don't want to; Then let us use action to prove it! We can start from me, start from now, start from the side. Love nature, the consciousness of environment protection! To do propaganda environmental protection angel! Let's take action to protect the environment

　　在21世紀(jì)的今天，人類的科學(xué)經(jīng)濟(jì)發(fā)展已經(jīng)達(dá)到了很高的水平。然而我想問：你們有沒有意識到人類的活動對環(huán)境會造成怎樣的影響呢?

　　森林的亂砍濫伐不就是一個嚴(yán)峻的問題嗎?據(jù)調(diào)查全世界森林面積正以每年上千萬公頃的速度在消失。造成大量的水土流失，使許多地區(qū)成為沙漠。人類的活動范圍在不斷減少，這不可怕嗎?

　　人類除了破壞森林之外，難道就沒有什么破壞環(huán)境的問題了嗎?不是這樣的�，F(xiàn)在我們應(yīng)該看到水污染的嚴(yán)重性，目前世界上60%的地區(qū)面臨供水不足，已有20%的人口難以得到清潔水，51%的人無法得到衛(wèi)生用水。這是什么造成的呢?是我們?nèi)祟愖约涸斐傻�，現(xiàn)在的工廠及我們生活中的污水，沒有通過處理就排出去。這不是最好的證明嗎?據(jù)研究，每排放1立方米污水，就污染14立方米天然水。想一想，這是多么可怕的數(shù)字?

　　在工廠排出的濃煙里，我們不知道濃煙是污染大氣的嗎?科學(xué)家發(fā)現(xiàn)，至少有100種大氣污染物對環(huán)境產(chǎn)生極大危害，直接影響人們的健康。

　　難道我們想在這種環(huán)境中生活嗎?當(dāng)然不想;那讓我們用行動來證明吧!我們可以從我做起，從現(xiàn)在做起，從身邊做起。樹立愛自然、愛護(hù)環(huán)境的意識吧!來做宣傳環(huán)保的使者!讓我們一起為保護(hù)環(huán)境行動起來吧
