I remember the "Earth Day" Leftists in the 60s saying we'd have 9 billion by 2030. Friggin loons.

A ggogle search on that 1968 book brought up this little tidbit:

"Population Bomb contained no specific statements about resources that could be checked. Ehrlich did, however make specific statements about resources in Population, Resources, Environment, published in 1970, as follows:

The U.S. should by now have run out of reserves of crude oil, uranium, manganese, cobalt, copper, chromium, nickel, lead, zinc, tin, aluminum, gold, silver and platinum.

The world should have already run out of each of the following minerals: lead, zinc, tin, gold, silver, platinum, and should run out of natural gas, copper and tungsten about the year 2000, and crude oil shortly thereafter."

I could easily find what he thought the population would be.
