TED TURNER UNLEASHED: ‘With only $500M, it is hard to afford a jet plane’

2008: Ted Turner predicts 'mass cannibalism' by 2040

He said drastic action – immediately – is required to address global warming.

"Not doing it will be catastrophic. We'll be eight degrees hotter in 10, not 10 but 30 or 40 years and basically none of the crops will grow. Most of the people will have died and the rest of us will be cannibals," Turner said.

He said civilization will have collapsed and "the droughts will be so bad there'll be no more corn grown. Not doing it is suicide."
