Beatles legend and famous vegetarian Paul McCartney was joined by John Lennon's widow Yoko Ono Monday to launch an appeal for "meat-free Mondays."
McCartney said going vegetarian, even for just one day a week, was good for the environment because of research suggesting it cuts greenhouse gas emissions from the world's livestock population.

Lennon's widow -- famously blamed for splitting up the Beatles, but clearly reconciled and on good terms with McCartney now -- added: "Give up one day and then it will be two days maybe. It's a very, very intelligent idea."
In a video on his website, McCartney noted that the campaign had already been launched in the United States and Australia.
"It's kind of easy to do. You?ve had too much over the weekend anyway and you're all running down to the gym to try and work it off so just have a meat-free Monday," he said.
