Last year, legendary investor Jeremy Grantham of GMO published a treatise on exploding commodity prices. He also offered a startlingly depressing outlook for the future of humanity.
Grantham believes the world has undergone a permanent "paradigm

Grantham believes that the planet can only sustainably support about
1.5 billion humans, versus the 7 billion on Earth right now (heading to
10-12 billion). For all of history except the last 200 years, the human
population has been controlled via the limits of the food supply.
