Bill Gates: To Reach Net Zero, 'You Don't Get to Skip the Cows'—Vaccination & Feed Changes Proposed

Bill Gates: "Cows are about 5% of global emissions... If your goal is to get to zero, you don't get to skip the cows."

"We've pursued many solutions. One is to vaccinate the cows."

"You can change what they eat, and you can either put that in their water or their feed."

"It's just a question of which solution for which country ends up being the best."
