fierce debate on human cloning has ever since been going on.This contentious iue has focused on ethical and social implications of the technology:what the technology might do to the very meaning of human reproduction,child rearing, individuality, etc.

The majority of scientists are adamantly opposed to reproductive cloning and support therapeutic cloning for treating diseases.The reason is that therapeutic cloning does not involve any type of relief of suffering in human beings.Scientists believe that with politics and monitoring in place to ensure that therapeutic cloning is used safely, we can all benefit from this procedure.

3.由于是人工生育而被认为缺乏道德，这样的苦境不是会糟糕得多吗？

4.因此，如果要禁止克隆人，其理由应比任何已经提出的更为有力才行。
