Investor Jeremy Grantham of GMO recently published a startlingly depressing outlook for the future of humanity.Grantham thinks the number of people on Earth has finally and permanently outstripped the planet's ability to support us.
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).
Basically, Grantham thinks most of us are going to starve to death.
Why?
