@60minutes: "Humanity is not sustainable. To maintain our lifestyle (yours and mine, basically) for the entire planet, you'd need five more Earths," biologist Paul R. Ehrlich told 60 Minutes in 2023. Ehrlich, who died Friday at 93, became a doomsday celebrity after his 1968 bestseller, “The Population Bomb,” warned of the collapse of nature. "I know there's no political will to do any of the things that I'm concerned with, which is exactly why I and the vast majority of my colleagues think we've had it; that the next few decades will be the end of the kind of civilization we're used to,” Ehrlich said. #environmentalist #Sustainability #biologist
