My sisters don't eat meat because of the horrible conditions we keep our factory farm animals in, what it's doing to the environment, and you don't need to eat meat to maintain a healthy diet (if you're educated.. Don't listen to the vegans saying they stopped because their hair fell out.) After watching an undercover factory farm video and witnessing the horrors that some of the terrible workers do to the animals for fun, I have a hard time eating meat. I'll probably be vegan some day.
