Stephen Hawking says pollution and 'stupidity' still biggest threats to mankind

> Professor Hawking said: “Six years ago, I was warning about pollution and overcrowding, they have gotten worse since then. The population has grown by half a billion since our last interview, with no end in sight.

When will the overpopulation argument die? It was wrong when the world was significantly less populated and poorer, and it's probably wrong now.

Wealth and prosperity are not natural resources that are harvested from nature. They are the results of human intellect and ingenuity.
