King Corn

I know a lot of people are talking about the documentary "Food Inc.", which I saw last year, but I wanted to mention a lesser-known (at least to me) documentary that I found really interesting.

King Corn is about two college students who decide to grow an acre of corn and trace it through the agricultural system. They discover the plight of the American farmer and what corn does to cows, among other things. It was really interesting and well done. Look it up!
