Eating meat is not bad for the environment. Look at all the carnivores in Africa, lions, cheetahs, leopards, gators, monkeys, hyenas, foxes, eagles, etc. Their meat eating has caused no damage, so why would you think humans eating meat would?
Eating organic range feed chickens...sounds good. But what you don't realize is they also eat their own crap! This is much less likely to happen if they are in coops, b/c it all falls through to the bottom. So yes they are free of hormones, but if they eat their own crap, I would just as soon not eat them. Give me a good steak.
Eat whatever you want, humans have been around for thousands of years, it isn't going to matter one way or the other to the environment.
