The desire for families is built into our genes; and since people have a right to reproduce, more people living a more abundant life is a perennial hope.

Too many people is arguably the most serious problem on the world agenda—for the adverse effects on human flourishing, on land health, and on biodiversity. . . . Cafaro and Crist have gathered much of the best recent work analyzing these daunting issues. In the new millennium no one can claim to be well educated, or moral, without facing ‘life on the brink.’
