Holdren, in his 1971 Sierra Club book, Energy: A Crisis in Power, declared that “it is fair to conclude that under almost any assumptions, the supplies of crude petroleum and natural gas are severely limited. The bulk of energy likely to flow from these sources may have been tapped within the lifetime of many of the present population.”
That dude could spout more out-of-left-field theories in ten minutes than anyone I’ve ever heard of. Biggest trouble was that the **** Sierra Club was funding him, so he could have postulated that Up is Down and they would have graven it in stone for him.
Have you ever heard of Soapy Smith? (Colorado and Alaska gold field con artist from the 1800’s)
Holdren’s got the same DNA.
