"The case against population is simple: Assume a fixed pie of wealth, and do the math. If every person gets an equal slice, more people imply smaller slices. The flaw in this argument is that people are producers as well as consumers. More sophisticated critics of population appeal to the diminishing marginal product of labor. As long as doubling the number of producers less than doubles total production, more people imply smaller slices. These anti-population arguments have strong intuitive appeal. But they face an awkward fact: During the last two centuries, both population and prosperity exploded." (05/02/11)
