         Do you know about Dolly, a famous sheep? She was created by cloning more than ten years ago in Scotland. Cloning is famous throughout the world. It is an experiment to make an animal that is exactly like its parent. So far, scientists have cloned rabbits, sheep, cows, mice, pigs and some other animals.
          But what is used in cloning? It’s DNA. There is DNA in most living things, including human beings. Your DNA is the same in every part of your body. For example, your fingernails have the same DNA as
your hair. You have your own DNA, which is similar to your parents’ , but not exactly the same. However, Dolly’s DNA is exactly the same as that of the sheep she was cloned from.
          No doubt cloning can help save those animals in danger. And it can also benefit human beings. The cloning technology has been used in human organs. With its help, scientists are able to explore more ways
to treat many serious diseases such as heart disease, AIDs and cancer. However, cloning could be used in some ways to harm society. All governments should make laws to make sure it can be used properly.

There is another reason for throwing less away. All of our trash has to be put somewhere. Often , it is put into garbage dumps (垃圾场). Much of that trash will be there for hundreds of years. The dumps will be filled up with all this trash.
