Paul McCartney "Glass Walls"

https://www.youtube.com/watch?v=sTifP6idBPs
"If slaughterhouses had glass walls everyone would be vegetarian", this is the line Paul McCartney uses many times throughout his video.  He is supporting that every one should become vegetarian.  His video is one of very few that actually shows and describes the way our food industry is working.  He uses the examples of chickens, pigs, cows and fish and shows videos of each that discourage you from wanting to eat this food.  One of the fats he presented is that if we continue to fish at the rates we do, then the ocean will be out of fish by 2048. We are fishing at such a tremendous rate that we are destroying our oceans.  ALSO, our food sources are the cause of many diseases, especially fish as a result of the consumption of mercury.  Overall, McCartney is one of the few people to go out and bash the food industry.  He shows people what our food is like before it is slaughtered.  It, along with Food Inc, is actually making me consider becoming a vegetarian.
