"Never has there been less hunger, less disease or more prosperity." That seems unlikely to me, given the recent growth of the world's population. I would guess there are now more people hungry than there were people alive some centuries (or couple of thousand years?) ago.

Maybe he is talking about percentages, or just the 20th century, or something like that?
