More on Cows and Climate

fart_cow_1Following up on the post below, this article in the NYT bears a look.  Some in the dairy industry (e.g. Stonyfield Farms) are experimenting with feeding dairy cows green plants instead of corn to see if it lowers their methane output.  Guess what?  It does.

Cattle fed alfalfa and flax emit less methane than those fed the industrial ag diet of corn and soy (apparently most of the emissions come from burps rather than the other… — who knew?).  Guess what else?   Cows that eat food that they can digest naturally also live longer than those who eat grain.

I suppose I should rejoice that the dairy industry has begun examining such issues but I am too busy worrying about the likelihood that dairy and beef cattle production will double over the next three decades.  As the article mentions, the cattle industry already poses more of a threat to the atmosphere than cars and trucks combined.  Somehow, I don’t think alfalfa and flax are going to solve this little problem.
