Do you know how much grass the cow has to eat to gain the energy it does? Herbivores have to eat all day long to gain enough energy to survive, and they spend the rest of their time sleeping. And human teeth are designed perfectly as omnivorous teeth.PersianLlama said:This is what I wanted to say. Also though, if the whole world was vegetarian you can feed more people from an ecological point of view. Every time something passes in the food chain/is eaten (For Example: Cow eating grass) about 10% (Just an average, not always this) of the energy is passed on. So if a human eats that cow that ate the grass, the human gets 1% of the energy, rather than the 10% a human gets from eating a plant himself/herself. So more plants = more energy = feeding more people. I'm a bit fuzzy on this, but I remember there was a question on one of my biology tests last year asking how more vegetarians would be better. Of course, this isn't really related to the environment, but it's still a valid point, I guess.Shivari said:Cows produce a ton of methane which does adversely affect the environment, and anyone who says otherwise has absolutely no idea what they're talking about.

But will one person going veggie help? No, that's way too small of movement to have an impact. Would everyone going veggie help? You bet it would, but not everyone is willing to do that because they're too busy justifying what they're doing so that they can continue eating meat. By continuing to eat meat you're still being part of the problem. Sure, the meat industry isn't dying out because little old you stopped eating meat, but as more people do it, it does have an impact. You can say that it makes no difference what you do by the time it's in the store, but by continuing to purchase the meat and support the industry, guess how much you're doing to solve anything? Absolutely fucking nothing.
And to the people above saying you need protein from meat. There's nuts and beans along with tofu.
According to my student teacher for Biology last year (I don't remember if my actual teacher verified this), human teeth aren't made for eating meat.
Carnivores get huge energy payoffs from killing and eating other animals, although they have to expend a lot of energy to catch and kill prey, but have to eat less frequently, herbivores spend all their time eating. Omnivores are superior to any straight herbivore or carnivore. We can eat nearly anything and are less penned in by the constraints of over-specialization.
And as for the environmental concerns, it doesn't matter, the only way the cows stop producing methane, is if they are exterminated.
