Tertullian

"Our teeming population is the strongest evidence our numbers are burdensome to the world, which can hardly support us from its natural elements. Our wants grow more and more keen and our complaints more bitter in all mouths, while nature fails in affording us our usual sustenance. In every deed, pestilence and famine and wars have to be regarded as a remedy for nations as the means of pruning the luxuriance of the human race." Paul Ehrlich in 1968? Al Gore last year? Nope. It was Tertullian, a Carthaginian priest in 210 AD
