Remember how your grandfather used to scream about the aliens hiding inside his couch? Maybe that's not a common experience. Anyway, with all due respect, the famous Australian scientist who is predicting humanity’s extinction in the next 100 years is, uh, 95 years old. Still, humans aren’t immortal; we’re likely to die out. Plus, it’s hard to deny that:
"The Aborigines showed that without science and the production of carbon dioxide and global warming, they could survive for 40,000 or 50,000 years. But the world can't. The human species is likely to go the same way as many of the species that we've seen disappear."
