The 6,544 tons of stuff the US takes from the natural world each year is 20 tons per person. Funnily enough, this is without even counting the CO2. When we burn those 1,936 million tons of fossil fuels they mix with oxygen to create CO2—around 6,700 million tons of the stuff. If we counted CO2 as one of the things we manufactured, it would, astoundingly, weigh more than everything else we push around combined!
