Happy Birthday Paul McCartney! The Beatles legend is turning 78 on June 18, and is also celebrating the 10th anniversary of Glass Walls, a heartbreaking clip in which he dives deep into the meat industry.
"All I've ever wanted for my birthday is peace on Earth—including for the animals," McCartney wrote in a new guest blog for PETA. "That's why this year I'm urging fans to watch a video I hosted for PETA titled 'Glass Walls.' We called it that because if slaughterhouses had glass walls, who would want to eat meat?"
