"We are meant to be herbivores." - xfile1971
This is simply not true. If you look at the enzymes present in our body, some of which are responsible for the breakdown of our food, you'll see that many of them are specifically tailored for breaking down animal proteins. To come at it from a different angle, we lack the enzyme necessary for the breakdown of one of the most common vegetable proteins--cellulose. I'm not saying that we should eat animals, but to say the word 'meant' as if it's some biological disposition of ours not to eat meat, is simply wrong.
I would recommend reading Michael Pollan's new(er) book, The Omnivore's Dilemma: A Natural History of Four Meals. The title really speaks to the dilemma that faces us humans and takes one deep into the food chains (don't think fast food chains; think circle of life food chains) that sustain our nation. I found myself coming away from the book with a much larger disdain for the people who run commercial food chains (now you can think grocery stores and their suppliers) and a desire to get back in "touch" with what it is that I'm eating everyday.
Also, I'd like to addd that I agree with you that I'd also one day like to see an end to the death of animals for the sake of human food. At the same time though, we must remember that this is simply an ideal, something which in the near term may likely not come to fruition. What we can do is be practical and advocate for better housing and care methods for our livestock. And also more humane ways of executing animals that are destined to become human food.
