In the 13th 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 15th century. However, people in China began to use paper money in the 7th century.

A Chinese man called Cai Lun invented paper almost 2,000 years ago. He put these pieces of paper together and made them in a book.

Now paper 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. So how can we save paper? We can use both of every piece of paper, especially when we are making notes. We can choose drinks in bottles instead of those in paper packets(小包). We can also use handkerchiefs(手帕) and not paper ones. When we go shopping, we can use fewer paper bags. If the shop assistant does give you 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. We should do it now, before it is too late.
