If a Cow Eats Chocolate. . .

Are American cows becoming junk food addicts? As corn prices soar, some meat producers are supplementing their herd's grub with cheaper foods, such as potato chips and M&M's, reports the Wall Street Journal. Adding an odd twist to a complicated issue, the cows' new diet could be another example of the biofuel effect. Sierra magazine details the recent backlash against biofuel, as developing countries and corporate giants blame U.S. subsidies for corn ethanol for increased food prices worldwide. While the big shots work it out, do your part by keeping in mind that cows are naturally adapted to eat grass, not corn or candy. Look for meat with the American Grassfed Association's certification and lower your carbon footprint by limiting the amount of beef (M&M-fed or otherwise) in your own diet.
