Paul McCartney says that if slaughterhouses had glass walls, everyone would be vegetarians. In his expose on meat.org, Glass Walls, tries to make slaughterhouse walls more transparent by exposing what goes on behind them. I think Paul McCartney’s work for animal rights is very admirable, although I know many people have a problem with some of the work he and former wife Heather Mills were involved in, especially regarding seals in Canada. That said, they both work tirelessly for this effort.
The video, like many others is VERY graphic, but I encourage you to check it out and share it with others.
