The author lists some of the negative implications of human cloning and concludes that we "start preparing ourselves mentally for that eventuality."

The author briefly details the risks from human cloning and germ line engineering and concludes with a call for "a new social movement-committed to affirming the integrity of the human species and opposing the new techno-eugenics and the post-human ideology."

The authors argue that the human germline is part of the "global commons" and should be internationally protected by using the precautionary principle to restrain research.

New research warns that a cloned child could die in infancy or be condemned to life as a freak or a cripple, amid claims by rogue scientists that the first human replicant may be born just months from now.

The author surveys the efforts of governmental advisory boards to come up with a strategy for dealing with the implications of the genetic revolution and concludes by calling for more resources to be devoted to public education and involvement.

Richard Hayes warns that scientists "are fast approaching the most consequential technological threshold in all of human history: the ability to directly manipulate the genes we pass on to our children."

Sally Deneen examines the ethical and environmental implications of human germ line engineering, including the potential risks of creating "designer babies."

The author reviews the arguments for and against cloning and concludes "reasons for permitting cloning to produce a person are insufficiently compelling. Even in the few circumstances where the case for human cloning seems justified, there are alternative solutions."

George J. Annas makes a moral and scientific case against human cloning and advocates for international adoption of the "precautionary principle" for all cloning research.
