not the poster you're replying to, but i felt the need to throw down my couple cents. i tried vegetarian/vegan for quite a while, but my body simply could not thrive. no matter how much "good" veg protein i got (and i'm a bit of a crazy about my diet...), no matter how much i wanted to save the animals, i just couldn't stay healthy. i can't speak for all humans, but from what i can tell from my own biology, i'm an omnivore - i have the teeth and digestive system of one. i require nutrients from both plant and animal sources. i cannot perform up to my full potential without animal products.
once i'd realized that, it came down to personal ethics. i refuse to buy meat (or most anything, really) from grocery stores. i'm lucky enough to live somewhere with lots of farms and markets; i speak with the farmers about the creatures they raise for slaughter, about how they're cared for, housed, and fed. there are proper ways to do these things, to raise livestock humanely and feed it a species-appropriate diet - so it can be healthy enough to live well and also be properly nourishing to those who consume it.
and to the poster you were replying to, you've got a noble goal there. i just recently took up hunting and would love to be able to bag enough wild game to greatly reduce or eliminate my dependence on farms altogether. until then, i'll choose the friendly local farmers.
