Some argue that procreation is immoral due to its negative environmental impact. Since living an “eco-gluttonous” lifestyle of excessive resource consumption is wrong in virtue of the fact that it increases greenhouse gas emissions and environmental impact, then bringing another human being into existence must also be wrong, for exactly this same reason. I support this position. It has recently been the subject of criticism, however, primarily on the grounds that such a position (1) is guilty of “double-counting” environmental impacts, (...) and (2) that it over-generalizes to condemn other clearly permissible behaviors, such as saving lives, or certain instances of adoption and immigration. Here, I will defend the environmental argument against procreation from these criticisms. I will do this, first, under the assumption that our individual consumption and emissions cause significant harm. I will then address the problem of causal impotence, and argue that, even if our individual contributions to environmental problems ultimately make no difference to the amount of harm that occurs, procreation is still immoral for many, if not most, of those living in the developed world.
