I've been vegetarian for 15 years. I started when I was seven for ethical reasons. My mother was vegetarian and she always taught me to respect every living being. I was already certain I didn't want to be part of such cruelty towards animals. Documentaries like Earthlings had a great part in my vegetarianism. As a matter of fact, I think that, if more people watched these documentaries and knew the cruelty hidden behind their "clean" steak, at least half of it would become vegetarian.
