King Corn. Don't know if anyone saw this yet but well worth the time. The part about corn feed cattle in this country was eye opening and shocking. One fact that was truly scary was the fact that %75 of the antibiotics used in this country are for livestock, thus we are consuming them too. Another fact that was interesting is that all the corn we grow now is unfit for human consumption. It must be processed, corn syrup being the largest end product.
