Cattle farts (and burps) put methane into the atmosphere. And since there are more than 900 millions cows on earth right now, that’s a significant contributor to climate change. Burger King is all for the beef industry, but they are taking baby steps, so to speak, to reduce cows’ methane production by giving them a new diet incorporating lemongrass. You can read more about the research here. Burger King is offering burgers made from cows fed the new diet in select cities now. The rest of us can just enjoy the cow fart song. -via The Takeout
