33. Some people believe cloning technology can be used to cure the patients with genetic diseases and save a lot of people’s lives. However, other people insist that cloning technology will cause ethical problem and violate human rights. No one can predict how negative the consequences could be. We have to take a cautious approach.
I don’t think it’s a good idea to clone humans even though we might have the ability to do so in the future. There are different reasons if you approach the issue from different angles. From the ethical point of view, I believe the disadvantages of producing cloned animals outweigh the advantages. If not handled properly, great confusion could arise. People could end up marrying their close relatives by mistake,if childless couples are allowed to clone themselves or adopt clones.Furthermore, if the technology is misused or stolen by evil people,great damage will be done.What if they cloned lots of criminals or murders?The world would be turned upside down.
