60% of crude oil imported into the US is burned as fuel (cars, trucks, power plants). One barrel of crude oil makes about 317 kg of CO2. The US consumes about 9,286,000 barrels/day (of gasoline, assuming it produces the same CO2 per barrel...). One average person produces about 0.90 kg of CO2 per day. The US alone produces the CO2 of 2.9 trillion people. China has the US beat on the production of CO2 also.
CO2 is the product of many things, but here are a few: Humans and animals exhale CO2 Decaying organic material (in land fills, for example) produces CO2 Burning organic material (forest fires, for example) produces CO2

The bonding of CO2 to hemoglobin produces carbaminohemoglobin. This process occurs in tissues where CO2 is released from cells and binds with hemoglobin to form a weak bond. This helps transport CO2 from tissues to the lungs for elimination.
