However , people in China began to use paper money in the 7th century . A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these 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 on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 trees every day . Since it takes more than 10 years for a 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 .

Clean air is all around us. People don't have to worry about polluting the air every time they drive their cars. They no longer need to face the problem of not having enough fuel either. Although scientists have been trying for many years to develop a new kind of car that does not need gasoline , _ have been unsuccessful. Recently, however, car engineers have succeeded in creating a new kind of car that runs on gasoline and electricity . This is the famous "hybrid car". This car gets its name from the fact that it has a gasoline engine and an electric motor inside. Hybrid cars do not pollute the environment as much as the cars that are commonly used today. They also cost drivers less money because they need less fuel than ordinary cars. Hybrid cars are becoming widely popular in the United States. They are soon expected to become widely used around the world. If scientists and engineers continue to work on car development, perhaps the world with clean air that we imagined earlier just might become real in the future.
