What is cloning? Originally it meant “asexual reproduction.” You can copy an organism, even a new life by developing the cells from the cell donor. Generally speaking, there are two types of cloning:therapeutic cloning and reproductive cloning. Therapeutic cloning can create specialized cells and organs in order to fight diseases while reproductive cloning can even give birth to a new humanbeing.
Dolly the sheep, the first cloned mammal from an adult, was announced in 1997 and it caused an international sensation. Since Dolly debut, scientists have created cloned animals such as mice,pigs, and monkeys, etc. Technologies of cloning were renewed. However, unfortunately, Dolly has been euthanized in 2003 for her premature aging and some kind of lung disease. Although Dolly has died, yetthe achievement of her creation was still a milestone in cloning science. On one side, it showed that human cloning would be possible in the future; on the other side, it also raised questions aboutpracticality of cloning life.
But what most of the people care are ethical questions. In a CNN poll, over two-thirds of the respondents think that cloning is immoral in any way. In 1997 when Dollywas announced, ex-President Clinton banned the use of federal money for human cloning projects. A few states have even passed laws banning human cloning though it was temporary. Now, the House haspassed a law supported by President Bush, which would ban all human cloning including researches. It shows that most people oppose human cloning, so do I.
I don’t object cloning, exclusive ofreproductive human cloning. I think that therapeutic cloning is proper and necessary because it can be used to fight diseases and create organs artificially. Nowadays, many people around the world wait for anorgan transplantation, but it is difficult to get suitable organs for themselves. What’s more, some people would buy organs in the third world or even extract them without donors’ permission. If...
