sort of where the u.s. sits in the world in terms of food, in terms of our energy consumption, right? the u.s. has 5% of the world population but we use 25% of the world's coal, 27% of the world's gas, right? we are the great consumers of the world's energy. but we also basically eat all the food, right? when you look at global calorie intake, the u.s. is the highest global calorie intake. we're using all the coal. we're eating all the food. is that why we don't act? because we feel well fed and like there's plenty of resources? >> two parts to the question. remember, most countries would love to get to the same level. i mean, if you look at china, they are now the biggest emitter of c o2 but at the same time while they use much more coal, very polluting, much climate impact, it's lifted 680 million people out of poverty. unheard in history.
