Paul McCartney is pushing for Meat Free Monday, a U.K.-based initiative encouraging people to reduce meat consumption to slow climate change, according to The Guardian. The goal is to persuade people that going veggie once a week—they've picked Mondays—will reduce greenhouse gas emissions from livestock, among the most serious contributors to global warming.
According to Meat Free Monday's website, "The UK's Food Climate Research Network suggests that farm to fork is responsible for between 20 to 30 percent of global green house gas emissions. Livestock production is responsible for around half of these emissions."
Linda McCartney Foods is showing its support by sharing a meatless recipe every Monday, starting yesterday with a vegetarian bolognese sauce. Other rock stars on board of the campaign: Sheryl Crow and Coldplay's Chris Martin.
