Today we’ll talk about the history of blue jeans. For many people, blue jeans stand for (代表) American culture.

The history of blue jeans usually began with a man named Levi Strauss. He did not invent jeans. But he is the first person to produce and sell them in large numbers. Levi Strauss was born in Germany. In 1847, he and his family moved to the United States. He opened a small store and sold jeans. These pants were especially useful for miners (矿工) in California. They needed strong clothing. Levi Strauss worked with Jacob Davis, who had invented a step for making rivets (铆钉) for jeans. They helped make the blue jeans stronger.

In 1873, Strauss and Davis received a patent (专利) to own this invention. Nineteenth century workers would probably be surprised to know that their pants would one day become fashions. Today, jeans are worn by people of all ages. Jeans come in many colors other than blue and in many styles and prices. Fashion designers even create very costly jeans. 

Writer James published a book called Jeans: A Cultural History of an American Icon (偶像). In the book, he says jeans serve as a sign for two American values, creativity and rebellion (叛逆).

The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution.

To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, drink it and even eat it. Pollution is beginning to threaten (威胁) our 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 and water. There weren’t so many people then and their wants 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 pollution and the development of industry(工业) have changed that. Man is slowly poisoning(毒害)not only his environment but also himself.

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(堆存处)，or is there any hope that we can get rid of (摆脱，除去) the pollution? Luckily, millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under control.

The earth is our home. We must take care of it. This means keeping the land, air and water clean. And we must take care of the rise in pollution at the same time.
