Many argue that cloning will benefit many people in various ways such as providing genetically related children for people who are infertile and allowing for stem-cell research. However, they choose to blatantly ignore the many risks associated cloning a human being. When man attempts to play God, it can never turn out well.
One of the risks that I'd like to discuss is the health risk from mutation of genes - an abnormal baby would be a nightmare come true. A particular worry is the possibility that the genetic material used from the adult will continue to age so that the genes in a newborn baby clone could be 30 years old or more on the day of birth. Many attempts at animal cloning produced disfigured monsters with severe abnormalities. So that would mean creating cloned embryos, implanting them and destroying those that look imperfect as they grow in the womb. However some abnormalities may not appear till after birth. A cloned cow recently died several weeks after birth with a huge abnormality of blood cell production. Dolly the Sheep died prematurely of severe lung disease in February 2003, and also suffered from arthritis at an unexpectedly early age
