Sir Paul McCartney says that global warming can be prevented if people across the world turn vegetarian.
The former 'Beatle' feels that the suggestion that livestock farming is done in mankind's favour borders on myth.
"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," the Mirror quoted the 65-year-old as saying.
"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," he added.
McCartney also recalled the spat his late wife Linda once had with the then President of the World Wildlife Fund, Prince Philip, over the shooting of birds.
"She said, 'You're the head of a wildlife organisation, how can you go out shooting birds?'" he said.
"'Are you vegetarian?' he asked, trying to catch us out. 'Yeah!', we both answered. Shooting birds, that's hypocrisy," he added.
