claim: Pollution; none of us are supporting putting substances into the  atmosphere or the waterways that might be pollutants, but carbon dioxide  is not a pollutant.
evidence: Flue gas from combustion of the fossil fuels contains carbon dioxide and water vapor, as well as pollutants such as nitrogen oxides ( NOx ), sulfur oxides ( SOx ), and, for coal-fired plants, mercury, traces of other metals, and fly ash.
