Today ’s technology develops so quickly that many impossible things become true; the cloning technology is the example. What is cloning? Cloning is the process of creating an identical copy of an original through nonsexual means.Different from the common propagate, cloning need only one cell and without sex. In 1997, the great news shocked the whole world that the British scientists created a lamp named Dolly from a single cell, miraculously; the cell had been taken from the udder of adult sheep, which show the first cloning experiment was successful.

When the cloning technology improves so quickly, many people have different opinions,In my opinion,cloning is a doubled-blade sword.Cloning can bring many benefits to the human, such as rejuvenation, helpful for Defective genes, Liver failure, Kidney failure and Leukemia. These disease are very different to cure, if we use the cloning technology we can change the Gene’s DNA order, so we can save lots of people. I agree to clone the endangered animal and disagree with cloning human. Because I think the cloning technology should be respected. It really can bring us many benefits; further more it can develop the science of human.But cloning still has some problems. The scientists found that the cloning animal’s Gene has a little different from the original animal. So the life will shorter than the real life. The fact proved that, the cloning sheep Dolly has died. It only has the half life of the common sheep.If clone the human, there will, however, be many problems, the population is the biggest problem. May be some people will use the cloning people to start the war. So I am against cloning human.

As far as I ’m concerned cloning has both advantages and disadvantages.We should make full use of it’s advantages to serve human beings, at the same time we try our best to avoid it ’s disadvantages.Only in this way our society will be more and more harmonious.

In the end, I think cloning is new technology, it should be accepted, how to look upon this technique, first we should know the advantages and disadvantages, then we should know the effect of cloning for human and the animal, third we will take the action: To advocate the animal cloning but be against with the human cloning.
