Linear food growth vs exponential population growth is more Malthus and technology does have the potential to grow food in an exponential kind of way. We do live in a time where the amount of food produced in the world is enough to feed every single person. There is just a problem of distribution and equity. Americans have so much food that half of it is thrown in the trash and even the amount that does get eaten is often too much food already and that why you see weight related illnesses on the rise like diabetes. In economics this is a major problem when you see oversupply in one area and shortages in another. It implies inefficient economics. Thanks for your comments.
