Belching Cows

Researchers at the Swedish University for Agricultural Sciences have just received a half million dollars to study belching cows. Believe it or not, methane exits each end of a cow as it consumes grass and grain. With millions of cows on the job, methane, a powerful greenhouse gas, adds up. Professor Jan Bertilsson joins host Bruce Gellerman to talk about how changing a cow’s diet might fight climate change.
