 What are the ethical issues regarding human cloning?
The possibility of human cloning has long fired the popular imagination, including in theworld of popular entertainment. For example, a thriller novel, the boys from Brazil, subsequently made into a 1978 Hollywood film, depicted a Nazi war criminal who raises a colony of young Hitler“clones”. For many others, cloning implied overtones of human immortality or of assembly line eugenics. Hoaxes wild claims and media speculation have inevitably intruded into the cloning discussion, sometimesoriginating more in pure science fiction than actual scientific experiments. Dolly gave added impetus to talk and concern about human cloning.
The cloning debate involves scientists, legislators,religious leaders, philosophers and international organizations, but not always harmoniously. General agreement, if not absolute unanimity, evolved that human “reproductive” cloning for the purposes ofproducing a human genetic copy baby is unethical. Sir Lan Wilmut explained to the United States congress that cloning a mammal involved a high failure rate, since of his 277 “similar experiments withhumans would be totally unacceptable”, Wilmut concluded.
The high failure rates (more than 90 per cent) and high morbidity of animal cloning strongly suggests its inapplicability to humans. Furthermore,cloned animals seem to suffer high deformity and disability rates. Dolly herself was finally put down in 2003, at the age of just six and a half years, even though many sheep live more than 10 years.She had developed a progressive lung disease, which is usually found in older sheep, as well as premature arthritis. Some cloning experts have consequently hypothesized that cloned humans might needhip replacement surgery while still adolescents and might suffer from senility by the age of 20.
The ethical ramifications of cloning, especially with regard to humans, seem to defy easy...
