Actor Mark Ruffalo took time out of his busy TIFF schedule to urge his fans to go meat free one day a week. "Join the fight against climate change & make your pledge to go meat free for one day a week #MFMclimatepledge [http://pledge.meatfreemondays.com/ ]," the Oscar-nominated actor tweeted Monday night. The Meat Free Monday pledge initiative launched yesterday a week ahead of the UN climate summit that’s to take place in New York City. According to the website, 14.5% of global carbon emissions are directly related to meat production. It’s the campaign’s hope that going vegetarian for at least one day a week will combat climate change in a major way. It will hopefully also act as a first step, paving the way for people to eat even less meat, or adopt a total vegetarian or vegan diet. (ecorazzi.com)
