Cut down on flying, sell the car and recycle your bottles. But if you really want to tackle global warming, you should stop your cow from burping.

According to scientific estimates, the methane gas produced by cows is responsible for 4% of greenhouse gas emissions. And now, German scientists have invented a pill to cut bovine burping.
