The earth is our home;we must take Care of it. This means keeping the land,air and water   clean.
Pollution is a dirty word. To pollute means to make things unfit(不合适的)or unclean to use. Pollution comes in many ways. We see it,smell it,taste it and drink it. Pollution is beginning to threaten(威胁)our health,or 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 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 wants(需求)were fewer. All the dirty things could be absorbed(吸收)by nature and soon. covered over(恢复), But this is no longer true. The increase of population(人口增长)and the development of industry have changed that. Man is slowly polluting. his environment.
Through the use of poison(农药),mall has polluted land! killing the animal. 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.

Do animals have a culture? What do we mean by "culture"? Recently social scientists have begun to ask if culture is found just in humans, or if some animals have a culture too.  When we speak of culture, we mean a way of life that a group of people have in common. Culture is the forms of behavior (行为)hat help people to live together. It is also the forms of behavior that make one group of people different from another group.

     Human beings use tools, cooperate with one another, and communicate with language.  But these aspects(方面) of human behavior, or "culture", can also be found in the lives of certain animals, Animals can make tools, for example. We used to think that the ability to use tools was the dividing line between human beings and other animals.  Lately, however, we have found that this is not the case. Chimpanzees(黑猩猩) can not only use tools but actually make tools themselves. Animals can also share knowledge with each other and use their own language to communicate. So it may be important for us to know that the line dividing us from animals is not as clear as we used to think.
