From a practical point of view . . . is there a shortage of human beings or problems with normal reproduction so that cloning a whole human being, rather than cellular or tissue cloning, is necessary? The worst application of complete human cloning would be "harvesting" or "vanity." The harvesting argument is that the richest or most influential would commission clones as a parts warehouse of their own body parts. The vanity application would be the preservation of a particularly admirable "human." Neither of these applications would seem to warrant cloning.
