Author Jared Diamond in a recent interview with The Financial Times:

“If we continue to operate non-sustainably, then in 50 or 60 years, the US and Japan and Europe will be in bad shape. But my friends in the highlands of New Guinea will be fine. Some of my friends made stone tools when they were children and they could just go back to what their ancestors were doing for 46,000 years. New Guinea highlanders are not doomed.”
