“Giving people the right to have as many people as many children that they want is, I think, a bad idea,” Ehrlich told Raw Story. “It’s not giving people the right to have as many children as they want, it’s giving people the right to control their reproduction so that they don’t have so many children that their children’s and grandchildren’s lives are in danger.”

“Nobody, in my view, has the right to have 12 children or even three unless the second pregnancy is twins,” Ehrlich continued. “That may be a hard-nosed view, but if you look at the entire situation, it’s crystal clear if we keep the populations of the rich growing, then the poor aren’t going to have a chance, and eventually, the descendants of the rich aren’t going to have a chance either.”
