From a post on another NG:
John Holdren has been named Science Advisor to President Obama.
For those too young to remember, a dude named Paul Ehrlich wrote a book in 1968 titled the "Population Bomb," in which he postulated the earth was running out of resources to provide for an ever-increasing population. Mass starvation, privation, and disease was but a few years away. Ehrlich argued for mass sterilization, abandoning over-populated countries, and other incredible solutions.
"Nonsense," denier John Simon cried. Simon offered to bet Ehrlich any amount that any five natural resources would be more plentiful and cheaper in any time frame Ehrlich chose.
Ehrlich accepted the wager and turned to his cohort, the now-advisor Holdren, to come up with the list. Holdren chose five metals - chrome, copper, nickel, tin and tungsten - and said they would be from scarce to non-existent in twenty years. Ehrlich and Holdren bet Simon $1,000 on the outcome.
Ehrlich and Holdren lost and had to pay up in 1990.
