Pollution(污染)is a “dirty” word. To pollute means to make things unfit or unclean to use. Pollution comes in many ways; we see it, smell it, taste it and drink it. Pollution it beginning to threaten(威胁)out health, out health, our happiness and our life.
Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another place. At first the problem was not so serious because there was plenty of clean air, land water. There weren’t many people and then their wants were fewer. All the dirty things could be absorbed (吸收)by nature and soon covered over. But this is no longer true. The increase of population and the development of industry have changed that. Man is slowly poisoning his environment(环境).
Once we thought of pollution, we simply mean air pollution. Though it is still the most dangerous, air pollution is only type of pollution.
Through the use of poison, man has polluted the land, killing the animals. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water, killing the fish.
Our increasing population is part of the problem. More people more waste.
Where is this all to end? Are we turning the world into a big rubbish dump(垃圾堆), or is there any hope that we can get rid of (除掉)the pollution.
