It would put into play wholly unprecedented social, psychological and political forces that would feed back upon themselves with impacts quite beyond our ability to foresee, much less control.

The implications for individual integrity and autonomy, for family and community life, for social and economic justice and indeed for world peace are chilling. Once humans begin cloning and genetically engineering their children for desired traits...
