Disadvantages of Human Cloning Essay Example

1. Health risks from mutation of genes - an abnormal baby would be a nightmare come true. The technique is extremely risky right now. 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 - say - 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 (presumably) 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 - probably linked to the cloning process.

Even if a few cloned babies are born apparently normal we will have to wait up to 20 years to be sure they are not going to have problems later -for example growing old too fast. Every time a clone is made it is like throwing the dice and even a string of "healthy" clones being born would not change the likelihood that many clones born in future may have severe medical problems. And of course, that's just the ones born. What about all the disfigured and highly abnormal clones that either spontaneously aborted or were destroyed / terminated by scientists worried about the horrors they might be creating.
2. Emotional risks - a child grows up knowing her mother is her sister, her grandmother is her mother. Her father is her brother-in-law. Every time her mother looks at her she is seeing herself growing up. Unbearable emotional pressures on a teenager trying to establish his or her identity. What happens to a marriage when the "father" sees his wife's clone grow up into the exact replica (by appearance) of the beautiful 18 year old he fell in love with 35
