They are EVIL! Just like Coca Cola, British Petroleum, and Monsanto. There are also many alternatives. USE 'EM!
Oh, I might as well throw the Coke boycott list up, too:
I betcha they sabotaged Odwalla in order to buy them out cheap. No proof, but go figure. I refuse to buy even their only good product now. Even if they haven't contaminated it with GMO, not that I trust them to not have.
