Paul McCartney is making noise in public and it’s not something to which you can sing along. In fact, it’s better. You can eat to show support. With the power of daughter Stella and other family members behind him, McCartney is pushing for Meat-Free Mondays. As meat production is responsible for 18 percent of greenhouse-gas emissions, the singer believes that one meat-free day per week is one way every person can make a meaningful change and help make the world cleaner and more sustainable. Joining McCartney in his quest for vegetarian Mondays are fellow famous faces such as Chris Martin, Kevin Spacey, Yoko Ono, and Woody Harrelson. One day a week sounds like a beautiful start!
