To Fight Global Warming, Eat Less Corn and More Flaxseed…If You’re a Cow
Cows could become a greater threat to global warming than cars or SUVs, scientists insist, which has prompted farmers in the U.S. and Europe to experiment with the diets of bovines. At issue is the tremendous amount of methane gas that cows expel as a result of digesting feed heavy on corn or soy, causing the average cow to produce “eruptions” (burps and flatulence) that total 200 to 400 pounds of methane each year. With the global production of dairy and beef expected to double in the next 30 years, adding millions more cattle, the expelling of methane by cows is now a serious concern, because methane has 20 times the heat-trapping ability of carbon dioxide.
