Will allow the elimination of diseases  Cloning is unlikely to be widespread so any dangers from any reduction in the diversity of the human gene pool will be so limited as to be virtually non-existent. The expense and time necessary for successful human cloning should mean that it will only be used to the benefit of the small minority of people who require the technology. The pleasure of procreation through sexual intercourse does not suggest that whole populations will prefer to reproduce asexually through cloning. The only significant lack of diversity which can be expected will be in women who suffer from a severe mitochondrial disease. They will be able to use cloning by nuclear transfer in order to avoid passing on the disease which is carried in their egg cells to any offspring. This elimination of harmful genetic traits from the gene pool is no different from the eradication of infectious disease, such as small pox, and should be welcomed. So against these very marginal worries there is potentially great good to be done through cloning. Currently already we have IVF and genetic screening which can prevent that babies with certain diseases are born. In 2000 the baby Adam Nash was born, genetically manipulated through IVF, as a genetic fit to cure his sister Molly from Fanconi anemia. [1] While this was not cloning it gives an idea what cloning could possibly cure. It could be a way of curing siblings from chronic diseases and also ensuring that the transplants (for example) will not be rejected due to genetic differences.
