This guy sounds like a total dick and isn't a stickler for details, but he does touch on an important conundrum stated more eloquently by other social scientists like Jared Diamond in his book "Collapse." The conundrum being that feeding people and providing them with vaccines, new crops and other means for a better life without checks on population growth can lead to some serious problems - competition for a limited amount of environmental resources probably being the biggest one. How do we ethically balance our concern for fellow human beings who are suffering in abject poverty on the one hand, and what kinds of problems overpopulation can lead to because of those same efforts in environmentally strained areas on the other hand is a tough question to answer.
