It is said that another acre of the world’s forest will be destroyed forever. Why is this happening? There are two reasons — land and wood. In many countries the trees have been cut down because the land was needed for animals or crops. In other parts of the world the trees are cut down because their wood is wanted. This wood is used by local people for firewood or it is used for building. But many people don’t know that in most places the trees won’t be replaced. The soil in the forests is very thin, but it is protected by the trees. When the trees are cut down, the soil is washed away by the rain or blown away by the wind. Soon nothing can be grown on it. The forest becomes a desert. Then more land will be needed, and more trees will be cut down.
When the forest is destroyed, it isn’t only the trees that are lost — the homes of millions of animals and plants are destroyed, too. All kinds of animals are in danger — fish，reptiles, birds, mammals, insects, and shellfish — as well as thousands of plants.
Who is to blame for this? The answer is simple: all of us. There are just too many people in the world. The world’s population is now six billion. Of course, it’s very easy to blame the local people. We don’t cut down trees. They do. But the products are bought by people like you and me — wood houses, beds, tables, chairs, paper… Why are the forests being destroyed? Just look around. You are probably using it right now.

In the 13th century, Marco Polo travelled a long way to China. He was a famous Italian 31 During his stay in China, he saw many wonderful things. One of the things he 32 was that the Chinese used paper money. People in 33 countries didn’t use paper money until the 17th century. However,people in China began to use paper money in the 10th century. 34 was invented by a Chinese about 2 000 years ago. His name was Cai Lun. He then 35 these pieces of paper together and made them into a 36 .
Now paper mainly comes from trees. We use it every day. 37 we waste a lot of it. If we keep on doing so, people 38 cut down many more trees. Then there will not be any trees left. If there are no 39 , there will be no paper.
So how can we 40 paper? When we making notes,we can use 41 sides of each piece of paper. We can buy drinks in bottles instead of 42 in paper packets. We can also use cotton handkerchiefs ( 棉手帕) and not the paper ones.
43 we go shopping, we can use fewer paper bags. If the salesman gives us a paper bag, we can keep it and 44 it later. We can help to protect trees if we think 45 . We should to it now,before it is too late.
