　　In the thirteenth century, the famous Italian traveler, Marco Polo, traveled a long way to China. During his stay in China, he saw many wonderful things. One of the things he discovered was that the Chinese used paper money. In western countries, people didn't use paper money until the fifteenth century. However, people in China began to use paper money in the seventh century.

　　A Chinese man called Cai Lun invented paper almost two thousand years ago. He made it from wood. He took the wood from trees and made it into paper. He then put this pieces of paper together and made them into a book.

　　Now paper still comes from trees. We use a lot of paper every day. If we keep on wasting so much paper, there will not be any trees left on the earth. If there are no trees, there will be no paper. Every day, people throw away about two thousand and eight hundred tons of paper in our city. It takes seventeen trees to make one ton of paper. This means that we are cutting nearly forty-eight thousand trees every day. Since it takes more than ten years for tree to grow, we must start using less paper now. If we don't, we will not have enough time to grow more trees to take the place of those we use for paper.

　　So how can we save paper? We can use both sides of every piece of paper, especially when we are making notes. We can choose drinks in bottles instead of those in paper packets. We can also use cotton handkerchiefs and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give us a paper bag, we can save it and reuse it later.

　　Everyone can help to save paper. If we all think carefully, we can help protect trees. But we should do it now, before it is too late.
