Cow flatulence breakthrough

Cows, it turns out, burp and break wind all day long, emitting about 14 percent of global methane gases. That's a problem "worth doing something about," said UK scientist John Wallace. And he has, Reuters reports, helping to develop a diet that makes bovine eruptions smell sweeter. In a 12-month trial, the new eats slashed ozone-damaging methane emissions by 70 percent. Still, even without this breakthrough, I'd rather live in the country.
