 Others are more skeptical about slippery slope arguments against cloning and think that effective legislation can prevent us from sliding down the slope (Savulescu 1999; Devolder &amp; Savulescu 2006). If reproductive cloning is unacceptable, these critics say, it is reasonable to prohibit this specific technology rather than to ban non-reproductive applications of cloning. The UK and Belgium, for example, allow cloning research but prohibit the transfer of cloned embryos to the uterus.
