So, since CO2 isn't a "pollutant" in the sense you mean, it's perfectly acceptable if the levels of atmospheric CO2 rise to 10 or 20 times their current levels, is that what you believe? Because if it's not a "pollutant," that means it's safe.
An amazingly convincing argument.
I think there is a large difference between a pollutant and a green house gas.
Life is pretty dependent on CO2, so it is quite hard to call it a pollutant.
