Pill stops cow burps and helps save the planet

"Cut down on flying, sell the car and recycle your bottles. But if you really want to tackle globalwarming, 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."

Really? As much as 4%? Can you really compare that to the pollution from cars, airplanes and heavy industry? I don't see it to be honest. Just leave the poor cattle alone, and concentrate on the heavy industry as they are responsible for a much larger portion of greenhouse gas emissions than the cows.
