Multi-billionaire and founder of CNN:

Ted Turner, speaking in 2008 about the need to depopulate the planet, to prevent "global warming":
"[Not moving off of fossil fuel] will be catastrophic. We'll be eight degrees hotter in 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."
"We've got to stabilise the population... We're too many people. That's why we have global warming. We have global warming because too many people are using too much stuff. If there were less people they'd be using less stuff."
With approximately two million acres of personal and ranch land, Ted Turner is one of the largest individual landholders in North America. Turner is also the founder and chairman of the United Nations Foundation, whose mission is to mobilise support for the UN and its Agenda 2030 Sustainable Development Goals.
