Pollan discusses how farms used to be with multiple crops and supporting just the farmers family and twelve others, now one farmer supports 129 with their crop. He also discusses the many other vast changes in the make-up of Indiana farms as well as farms nationwide. This is due largely in part because of a man named Fritz Haber who figured out how to use nitrogen for fertilizer. Because of this invention corn can be grown more efficiently and in tighter places than ever before.
Another major reason why corn has taken over farms everywhere is because of the government subsidies which has lead to farmers being forced to grow corn over other vegetables because the government will pay for someone to lose a lot of money growing corn rather than a bit on a different product. There are many other interesting facts in this chapter but those were just the main ones.
