A number of journal articles have discussed a popularized debate between Paul Ehrlich (a population doomsdayer) and Julian Simon (an optimist). Simon posits that resources are unlimited, and I'm trying to understand the dynamics of that hypothesis. >> . . .up until about the 1950s gold could only be mined if there >> was greater than around a half ounce per ton of rock (+ or – >> depending on the deposit), but now deposits are being mined that >> have less than 0.3 ounces per ton. Good data, thanks.
