Bill Gates: 6% of global emissions are cows who burp and fart methane to an extreme degree

"You know, what happens with beef, my climate group Breakthrough Energy just announced literally today an investment in an Australian group called Ruminate that helps cows not be so much a source of methane emissions. So we have two paths to solving that. That's 6% of global emissions are cows who burp and fart methane to an extreme degree.
You can either fix the cows to stop them doing that, or you can make beef without the cow. And both of those will be pursued to see which one can lead to the best product in terms of taste, health, and cost."
