To feed a growing global population, which could reach 9.1 billion by 2050, world food production will need to rise by 70%.

That isn't a 70% increase in population, so why is it a 70% increase in food needs?

Stop growing crops for fuel and you'll have some food back in supply for dining.

Agree, given the obesity epidemic, I don’t think there’s a one-for-one correlation. Also, to break bad news to the doomsayers, I doubt world population continues to increase that fast, as it’s slowing down everywhere, particularly in the Third World.
