"CO2 is a pollutant only when emitted by human sources... Nature's production of CO2 is not a pollutant, but human production of CO2 is. Again, just wan to be perfectly clear exactly what you believe concerning CO2."


I didn't say that nature's production of CO2 is not a pollutant, did I?  The human body recognizes that CO2 is a pollutant.  It is why we exhale, dude; to get rid of the excess CO2 and other unwanted gases.  But can't control all natural sources of CO2, nor do I think we need to.  We do need to control the amount we emit.  We can do that.
