Burger King battles cow fa–ts, er, cow gas

(Miami, FL) — Burger King is tackling climate change with a new Whopper on the menu today. The burger is made with beef from cows on a low-methane diet. The fast food chain worked with scientists to give its cows 100 grams of lemongrass leaves a day. That’s been shown to help them release less methane as they eat. Right now, the new burger is only in Miami, New York, Austin, Portland and Los Angeles.
