Billionaire environmentalist says world has too many people Failure to address global warming will have us all dead or eating each other by mid-century. So says Ted Turner, the restaurateur, environmentalist and former media mogul whose controversial comments have earned him the nickname "Mouth of the South." 30 or 40 years and basically none of the crops will grow," Turner said during a wide-ranging, hour-long interview with PBS's Charlie Rose that aired Tuesday. "Most of the people will have died and the rest of us will be cannibals," said Turner, 69. "Civilization will have broken down. The few people left will be living in a failed state â€” like Somalia or Sudan â€” and living conditions will be intolerable." One way to combat global warming, Turner said, is to stabilize the population. "We're too many people; that's why we have global warming," he said. "Too many people are using too much stuff." Turner suggested that "on a voluntary basis, everybody in the world's got to pledge to themselves that one or two children is it." Admitting that he's "always suffered from foot-in-the-mouth disease," Turner added, "I've gotten a lot better, though. It's been a long time since anybody caught me saying something stupid."
