Paul McCartney has taken an initiative to convince people to cut down on meat from their diet with the help of a new song, it has been revealed.
The former 'Beatles member has taken the initiative to encourage people to eat a flesh-free diet once a week in an effort to slow climate change ahead of this week's United Nations summit, the Daily Star reported.
The song's video also features actors Joanna Lumley, Woody Harrelson and model Twiggy.
