Years later the EPA decided that green house gases were air pollutants that could be regulated under the act. Then they tried to say that CO2 was a pollutant, and businesses started to fight back hard.

> Pollution, the addition of any substance (solid, liquid, or gas) or any form of energy (such as heat, sound, or radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form.
