Paul McCartney has urged the Western world to turn vegetarian to help fight climate change.

He said recently: “Livestock farming is one of the biggest destroyers of the planet. When you see the Amazon being cut down for hamburger cattle, that’s pretty obvious.”

“And it’s all done in the name of something that benefits humans, when in fact it’s the opposite. It’s all about attitudes, no one thinks they’re the one who has to change.”
