I agree with you guys! Sense you brought a very good comparison between Cloning and Nuclear Reactors. I was also considering the same concept when i was preparing my seminar on one of the papers that was published by the Korean Scientists in "Science"- Therapeutic cloning something similar to generating electricity from the Nuclear reactor and Reproductive cloning something that would be equivalent to making a Nuclear bomb!! And of course most Scientists of the present world do not favor human cloning!! But there might be some scientists they are just crazy about cloning human and in fact Clade is the name of a company that has claimed that it has already cloned human. This report is to be verified independently. As i started looking deep into the therapeutic cloning, there also you have to destroy a lot of human embryos and the success rate of SCNT is something around 20%. That means to produce 20 blastocysts you have to sacrifice 100 human embryos. And there comes the ethical and health related issues related to the egg donor (the mother). She has to go through unnecessary risk of taking high dose of drugs that stimulate the production of ovum from her uterus and other invasive procedures. And of course there are reports of toxicity related problems with the tissues that were prepared from the therapeutic cloning. Well there are some reports where instead of human egg Scientists are working on ways to find procedure for using animal (other mammals) eggs for the therapeutic cloning. Let?s hope that would make things easier in the coming days for the patients with Neurodegenerative diseases such as Parkinson's disease and Diabetic patients who have completely destroyed their terminal beta-cells- insulin producing cells. These are the very few examples where therapeutic cloning that can be used. But again there are lots of chances where even therapeutic cloning could be misused! So be careful about this!! Well Matrix Gal has also brought good points about the cloning! I expect from you guys to comment more about ethical issues that are related to cloning human embryoning stem cells!! Nut
