It turns out cows breathe out a *lot* of methane, enough to account for 20% of the methane in the atmosphere – about 100-150 gallons per cow, per day.
Biochemist Stephen Ragsdale at U-Nebraska is trying to develop a feed additive to reduce the problem. Besides reducing atmosperic methane, this may also save farmers money – about 16% of what cattle eat ends up just being used to produce methane.
Maybe they could just fit the cows with snorkels, and harvest the methane for power production. Gary Larsen, where are you when we need you?!
