I have sent Planetair.ca, the David Suzuki linked Carbon-Credits site the following followup query:
"The pollutants we pump into our atmosphere are enhancing its ability to trap heat (the ‘greenhouse gas effect’) and increasing the earth’s temperature. Today's atmosphere contains 32 per cent more carbon dioxide, one of the main greenhouse gases, than at the start of the industrial era."
On what grounds do you consider carbon dioxide, a naturally occurring substance, a "pollutant"?
Stay tuned for the answer.
