This video crossed my path again recently. It’s Albert Bartlett’s famous lecture, “Arithmetic, Population and Energy” and it’s billed in this youtube video as “the most important video you’ll ever see”. I’d agree with that. I think the world’s brain-dead politicians should be locked in a room together and made to watch it. But then, I expect very few, most likely none of them, would have the mental capacity to understand it. We wouldn’t have the unsustainable, useless society we have, if that were so.
