You seem to love the environment a lot, so tell my; Why are you a Vegetarian/Vegan (Can't remember which). Overgrazing is one of the biggest environmental issues the world faces, and not eating meat is adding to it. Sure, you can say that the fields wouldn't be overgrazed without meat production, but consider how mad the problem'd be without the meat industry. Cows'd run rampant. Fields would be nonexistent. There'd be a larger amount of Methane in the atmosphere. Just something to think about.
