That’s one cow for every five people on Earth. We keep them for dairy and meat, and they’re a climate problem that we’ve struggled to solve. Every year, each one of those cows is estimated to release up to 220 pounds of methane, mostly when they burp.

But instead of trying to convince billions of humans to change their diets, some researchers are focusing on the diet of the cows.

It allows them to dig
