Question

  There are three reasons why I don't think that we are ready for cloning.

  Firstly,we don't know exactly what the consequences of cloning would be. For example,if scientists cloned a man,they might know what he would look like,but they wouldn't know his dominant traits. What would happen if scientists cloned another Hitler or others like him? Do you really think we would survive if this became a reality?

  Secondly,cloning raises many ethical questions. Look back at the cloned man I presented and ask yourself these questions ：

  "Do you really think that he would be a man?"

  "Who would be responsible for him?"

  "Do you think he should have the same rights as we have?" I don't think that we can answer these questions now.

  Lastly,we don't know exactly what the meaning of life is. In my opinion,creating life is the duty of nature,and we must not interfere with that task be?cause we can't understand the extremely complicated relationships among lives that are defined by nature. Usually these relationships are extremely complex. Sometimes,they seem to be so untouchable that they cannot be changed. From my point of view,we have to look at the natural environment around us. We can see that an ecosystem (生態(tài)系統(tǒng)) is composed of a lot of different kinds of life,and each life has its own function within the system. If we inter?fere with that,I think it could lead to our extinction.

  Even though cloning may have a lot of benefits for humans,I think we should stop cloning because we do not understand it and can't control all of its effects. Maybe in future,we will be ready to do it,but that time has not yet arrived.
