1、As we all know, pollution is harmful to living beings. There are many different types of pollutions in this world. For instance, water pollution, air pollution, noise pollution and so on. Water pollution cause many kinds of disease that have negative effects on human beings, sometimes the diseases will take people’s life away. Dirty air will increase the rate of getting lung cancer. While the noise pollution will cause insomnia. People’s health condition will be damaged.

　　2、In my humble opinion, people should take measures to control the pollution. Recently, not only the government, but also individual has taken part in the action of protecting the environment. This is a good sign. Rivers are being cleaned, air is purified, and the people come to realize that the importance of protecting the environment.

　　3、However, this is not enough, the problems are still exist. Not all of them have been solved. Some factories are still pouring dirty water into the rivers or give off the toxic gas into the sky. We should know that protecting the environment needs everybody’s effort.

　　4、我們都，污染對生物大危害。在這個世界上，有許同類型的污染。例如：水污染，空氣污染，噪音污染等等。水污染會使人們生病，甚至死亡。髒空氣會使患肺癌的幾率上升。而噪音污染會讓人失眠。人們的健康水平會下降。

　　5、在我看來，人們應該采取措施去保護環境。最近，不僅僅是政府部門，個人也參與到環保中去。這是個好現象。河流幹淨了，空氣清新了，人們也意識到環保的重要性。

　　6、然而，這些還遠遠不夠。問題依舊存在。不是所有的問題都得到了解決。一些工廠依舊往河流裡面排放污水，向天空排放有毒氣體。我們應該謹記環境保護需要每個人的努力。
