Oh give me a home where the buffalo roam,
and I'll give you a whole lot of gas.
PHYSORG.com reports on a study by scientists at the National Institute of Agricultural Technology in Argentina. By attaching plastic balloons to the backs of cows and running collection tubes from their stomachs, scientists were surprised to find that a standard cow produces between 800 to 1,000 liters of "emissions" (mostly methane) each day.
Why do this?
Well, if you must know, methane is 23 times more effective than carbon dioxide at trapping heat in the atmosphere.
The misguided scientists are now studying how changes in a cow's diet can reduce the amount of methane. It seems to me that capturing and using the methane as an alternative fuel would make a whole lot more sense. I'm studying this myself, and I'll give you an update on my findings.... as soon as I can get my feet back on the ground.
