Human reproductive cloning is a constant topic.Now a lot of public opinion is related to human reproductive cloning.But I still can't judge this technique is good or bad. When I have read text of Human cloning:A scientist's story,I have learned that Human reproductive cloning is just simply wrong ethically from a medical standpoint and a scientific standpoint.Because the majority of reproductive clones in other species are actually abnormal,with very high miscarriage rates,very high stillbirth rates,fetal anomalies,death soon after birth.what's more,many different studies or finding could be used for evil. In a word,it does make sense to me that it's such an Emotional and contentious topic. I have study many knowledge related to Human reproductive cloning.people say that everything have two aspects,No exception this technique can bring people benefits but also harm.For example ,if Human reproductive cloning have developed,it's contribution in the medical will be very great,many disease now can't be cure will be cure,like HIV.On the other hand ,people worry about the emergence of human cloning will cause social disorder.No one wants to another ourself. However ,we shouldn't stop the development of this Technique.Of course we must be appropriate to use the technique.
