My View on Human Cloning
北京 刘萌萌
Simon’s Revised Composition:
A decade ago,it was unrealistic to clone a human being.But all has changed since a sheep named Dolly,an exact genetic replica of its mother,was born on July 5,1996.People all over the world began to discuss this new technology seriously as the principle of human cloning is the same as that of animal cloning.Fierce debate arose over the pros and cons of trying to clone a human being.
Indeed,every fruit of science has a prospect of wide application.Many problems regarding human reproduction or medicine may be solved with human cloning.How exciting it would be when the life of a patient with a malfunctioning organ could be saved as a suitable replacement could be easily grown in a laboratory.Such transplants would also eliminate the risk of rejection by the body due to an immune reaction as the new organ would be cultivated from a batch of cells from the patients themselves.And what a joyful thing it would be if a copy of a person could be made to overcome infertility.
However,a large number of people including Ian Wilmut,who created Dolly,find human cloning offensive.For one thing,the technology is far from perfect and the incidences of a live and healthy clone are few and far between.Shall we kill off the ones with a deformed body or defective brains?That,I’m afraid,would cause censure from people who hold to their religious beliefs.For another,even if the technology is perfected,who can guarantee no one will misuse it for evil purposes?
I agree that the evil use of human cloning will lead to very dangerous consequences.But I don’t agree with the idea of prohibiting it.Nothing can stop the advancing steps of science.As world history teaches us,if one society rejects a new technology,another society will not.I think there is still a long way to go to judge whether cloning has more advantages than disadvantages or not.
