Amid the global financial crisis, terrorism threats and other challenges capturing the attention of global leaders, the climate crisis still "needs to be tackled urgently," Greg Barker, MP and Climate Advisor to the U.K. Prime Minister, told The Dodo. He launched the Meat Free Pledge with McCartney, and feels that going meatless for one day is a tangible way that members of the public can "do something that is more than just a token gesture."
When a family of four skips steak one day a week for a year, it's like taking their car off the road for three months, Environmental Working Group suggests.
It's "aspirin for the environment," founder of The Monday Campaigns Sid Lerner told The Dodo. What began as a health initiative quickly grew to include everyone from "animal rights-type friends" to "Paul McCartney with global warming, so it's now a banner that covers many people."
