What's the big deal with grass-fed beef? I can't imagine cows enjoy it. If I lived the life they did, I would for sure want to enjoy a juicy steak from time to time. With some frites. Especially if I'm on a farm in Paris.
Besides, I think cows should use their own product if they're going to sell it. Remember the Hair Club for Men commercials. The President wasn't just the President. He was a client too.
Cows should eat beef every once in a while. I'm more likely to eat them if they do.
