The issue with "do plants have rights too" stirs my brain into a frenzy!! I am just now, looking to explore the emotions and make the right choice rather than just continue along oblivious.
yes and no - we derive from monkeys who are known to be herbivores engaging in only instances of carnivorous behavior. Research indicates that our early ancestors relied mostly on the kills of other animals like a hyena or vulture. So as far as our ancestors go we depended primarily on veggies - its only very recently that meat arrives as a mainstay for humans - even then as Mr. Walker correctly points out, most of the world does not consume meat in vast amounts simply b/c it can be an expensive commodity.
