pReproductive cloning is creating a person or an animal that is genetically exactly the same as another. Therapeutic cloning uses human embryos for research and to develop cures for diseases. In many countries, the second two types of cloning are illegal.
Dolly the sheep was the product of reproductive cloning. She gave birth to six baby sheep during her life, but by the age of six, she was seriously ill. She had cancer, and was put to sleep. Most sheep live for eleven or twelve years, but Dolly only lived for six years.
While people worry about cloning leading to similarly early deaths in humans, people have many other worries as well. People worry that if we allow cloning, scientists will be able to create copies of people, which many people believe is not natural. People are also concerned about the effect on society, and worry that there will be many clones walking around everywhere. However, cloning does have benefits. DAN cloning can be used to build organs that can be given to people with failing organs who are waiting for transplants. Therapeutic cloning can be used to help disabled people walk again and to help cure diseases such as cancer. Many governments have made therapeutic cloning illegal, though, because it uses embryos for scientific research. Many people do not like the idea of creating new people and animals for science.
Despite the arguments against it, cloning can benefit people all over the world. However, because it means that scientists could copy people, a lot of people would like to see it banned. What these people need to understand is that there are different types of cloning, and that cloning itself is not the problem. The problem is what we choose to use cloning for.
