Cows are being bred to pass less gas in an effort to make them friendlier to the environment. Each day a cow can produce 42 gallons to 85 gallons of methane, which has 28 times the global warming potential of CO2, meaning dairy cattle’s burps and farts account for 14 percent of global warming gasses. Scientists are locating those cows that produce the least amount of methane and they will breed them into existing herds. Experts are also testing fart-free feed. (The Sun)
