Many vegans choosed this lifestyle because they feel sorry for animals. They're eating only plants, but aren't plants living things too? Is there any proof that plants don't have feelings or thoughts? Even if they don't, they're still living things. And humans are natural omnivores, it's true that we accomplished many things which we weren't naturally supposed to, but is it good to surpress our need of meat and other animal products? Even if all humas stopped eating meat, there will still be other carnivore and omnivore animals, so the killing of animals will never stop.
