Pollution is a “dirty” word. To pollute means to make things dirty. Pollution comes in many forms. We see it, smell it, drink it and even hear it. 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, man moved on to another place. At first, the problem was not so serious because there was plenty of clean air, land and water. There weren't so many people then and their needs were fewer. All the dirty things could be absorbed by nature and soon covered over. But this is no longer true. The world is becoming too crowded. We are using up our natural resources too quickly and at the same time we are polluting our environment with dangerous chemicals. If we continue to do this, human life on the earth will not survive. Now, more and more people have realized how serious the problem is. We have begun to try our best to do something to protect the environment. We hope that all the people in the world will take good care of our earth and make it a better place to live in. 1. What does the word “pollution” mean? A. Making things clean. B.
