The reason given for not classifying CO2 as a pollutant is based upon the fact that it is a natural component of the atmosphere and needed by plants in order to carry out photosynthesis. No one would argue the fact that carbon dioxide is a necessary component of the atmosphere any more than one would argue the fact that Vitamin D is necessary in the human diet. However, excess Vitamin D in the diet can be extremely toxic.

Living systems, be they an ecosystem or an organism, require that a delicate balance be maintained between certain elements and/or compounds in order for the system to function normally. When one substance is present in excess and as a result threatens the wellbeing of an ecosystem, it becomes toxic, and could be considered to be a pollutant, despite the fact that it is required in small quantities.

Carbon Dioxide (CO2) is not pollution and Global Warming has nothing to do with pollution. The average person has been misled and is confused about what the current Global Warming debate is about, greenhouse gases. None of which has anything to do with air pollution. People are confusing Smog, Carbon Monoxide (CO) and the pollutants in car exhaust with the life supporting, essential trace gas in our atmosphere, Carbon Dioxide (CO2). Pollution is already regulated under the Clean Air Act and regulating Carbon Dioxide (CO2) will do absolutely nothing to make the air you breath "cleaner". Carbon Dioxide (CO2) is actually plant food. They are also misled to believe that CO2 is polluting the oceans through acidification but there is nothing unnatural or unprecedented about current measurements of ocean water pH and a future rise in pCO2 will likely yield growth benefits to corals and other sea life. Thus regulating Carbon Dioxide (CO2) emissions through either 'Carbon Taxes', 'Cap and Trade' or the EPA will cause energy prices (electricity, gasoline, diesel fuel, propane, heating oil ect...) to skyrocket.
