Carbon dioxide | CO2 - PubChem

Carbon dioxide is naturally present in the atmosphere as part of the Earth''s carbon cycle (the natural circulation of carbon among the atmosphere, oceans, soil, plants, and animals). Human activities are altering the carbon cycle-both by adding more CO2 to the atmosphere and by influencing the ability of natural sinks, like forests, to remove CO2 from the atmosphere.
