JulianSimon|Wager
JulianSimon and PaulEhrlich entered in a famous wager in 1980,
betting on a mutually agreed upon measure of resource scarcity over the decade leading up to 1990.
Simon and Erlich agreed to bet on the price of several commodity metals. Erlich chose 5 metals: copper, chrome, nickel, tin, and tungsten.
JulianSimon won handily.
(More details should be filled in here.
this page has a lot of detail, and presumably somewhere we could find a pro-Ehrlich page to find out if there are any additional counter-arguments.
