Paul McCartney became a vegetarian in 1975, thanks to his wife Linda, who campaigned for animal rights before it became fashionable, and later wrote internationally bestselling vegetarian cookbooks. Decades later, Sir Paul still remains committed to the cause, encouraging people to skip eating meat once a week -- see his Meatless Mondays web site -- and persuading figures like the Dalai Lama to walk the walk. Above you can watch the Paul McCartney-narrated film, Glass Walls. It works on his theory that "if slaughterhouses had glass walls, everyone would be vegetarian." That is, if you saw how most every carnivorous meal starts with absurd amounts of suffering suffering, you might question whether you personally want to support this.
