When I talk to people about controlling the population of the Earth, the subject of birth control often comes up as a potential solution. I can say all I want that "birth control might work on an individual level, but it doesn't work on a group level," but I don't really have any facts to back up this claim. What arguments can I put forth to back up the claim that birth control won't work to control our population as a whole? • Ishmael.org, the work & philosophy of Daniel Quinn
