Dolly the sheep resulted from a cloning experiment by a group of Scottish scientists in 1997. A fierce debate on human cloning has ever since been going on. This contentious issue had focused on ethical and social implications of the technology: what the technology might do to the very meaning of human reproduction, child rearing, individuality, et cetera.

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 risk to human life and actually provides tremendous potential for the relief of suffering in human beings. Scientists believe that with policies and monitoring in place to ensure that therapeutic cloning is used safely, we canal benefit from this procedure.
