Bill is simply a movie supervillain.

Bill Gates: "Cows and other grass-eating species have a digestion system that emits methane. And methane is a very powerful greenhouse gas. And so cows alone account for about 6% of global emissions. And so we need to change cows, just cows alone."

"Actually of all the categories, the one that has gone better than I would have expected five years ago is this work to make what's called artificial meat. And so you have people like Impossible or Beyond Meat, both of which I invested in."

"You can go to Burger King and buy the Impossible Burger. All right, is it healthier for you, or just healthier for the atmosphere? It's slightly healthier for you in terms of less cholesterol. It's, of course, dramatic reduction in methane emissions, animal cruelty, manure management, the pressure that meat consumption puts on land use."

The main reason why we need to increase the agricultural output over the rest of this century is not the population increase. It's that as countries get richer, they eat more meat. And meat is a very inefficient way of creating calories."
