OK, I'm a bit late catching up to this but just seen a video called If Slaughtehouses Had Glass Walls Everyone Would Be A Vegetarian hosted by none other than Sir Paul McCartney himself. Pretty shocking stuff on how animals are treated, I've seen similar footage before but this short film really concentrates all the horrors in one place... Definately worth the watch, I don't think I'll ever be a full vegetarian but it definately made me want to strongly diminish the quantity of meat I eat...
