In a PBS interview CNN founder Ted Turner says if global warming continues people will cut out the middlemen and start eating each other to survive. If steps aren't taken to stem global warming, "We'll be eight degrees hotter in 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
