Abstract
The author discusses the effects of contraception, which have borne out the predictions of Pope Paul VI's encyclical Humanae Vitae: the explosion of out-of-wedlock births, lack of respect for women, STD's, HIV/AIDS, etc. The overpopulation claims that fed the acceptance and promotion of contraception have been discredited by demographers; now the social costs of underpopulation are increasingly apparent. Acceptance of contraception has now also led to an embracing of morally objectionable technologies like cloning. This is the latest consequence of the separation of sex and reproduction signaled by the acceptance of contraception.
