Nowadays, with the development of science and technology, cloning has become a hot topic for many people. Some people are against it ,while others are in favour it. Personally, I wouldlike to say that cloning is good
the human race.
, cloning technology proves helpful for genetics researchers. With cloning technology, scientists
bring some animals that are extinct back to life. Secondly, cloning body parts can serve as a lifesaver for people
are seriously ill. When a body organ such as a kidney or heart fails to function, it may be possible to replace it
a cloned one. Thirdly, if a couple can’t have
child, human cloning technology will make it possible for them to have a child. All in all, I firmly believe that cloning is beneficial
the human race.
