A call went out on Tuesday for an international ban on reproductive human cloning. The proposal would still allow for "therapeutic cloning," an exception opposed by the U.S. and other countries, but at least the scientific community recognizes that "reproductive cloning was so dangerous - regardless of any moral qualms - that a worldwide ban was needed as soon as possible." As Britain’s Lord May observed:

Animal studies on reproductive cloning show a high incidence of foetal disorders and spontaneous abortions and of malformation and death among newborns. There is no reason to suppose that the outcome would be different in humans.
