This paper defends the Famine Relief Argument against Having Children, which goes as follows: conceiving and raising a child costs hundreds of thousands of dollars; that money would be far better spent on famine relief; therefore, conceiving and raising children is immoral. It is named after Peter Singer’s Famine Relief Argument because it might be a special case of Singer’s argument and because it exposes the main practical implication of Singer’s argument—namely, that we should not become parents. I answer five (...) objections: that disaster would ensue if nobody had children; that having children cannot be wrong because it is so natural for human beings; that the argument demands too much of us; that my child might be a great benefactor to the world; and that we should raise our children frugally and give them the right values rather than not have them. Previous arguments against procreation have appealed either to a pessimism about human life, or to the environmental impact of overpopulation, or to the fact that we cannot obtain the consent of the non-existent. The argument proposed here appeals to the severe opportunity costs of parenting. (shrink)
