And sadly, a lot - a LOT of arable land is used to create cheap corn-based sweeteners so that farmers in Louisiana who used to grow sugarcane now have to make it with soybeans. Brazil's ethanol comes from sugarcane waste. Ours comes from cow food. Real smart.
Did I mention the amount of water that's used in the name of farming corn we don't need, and that you and I are tax-susidizing that, too? Must be nice to be Monsanto.
