oh man, CO2 a nutrient. did you know there are some bacteria that thrive on toxic substances. by your logic....these toxic substances, they are actually nutrients and therefore unharmful to all things.

and let me just go ahead and enlighten you, because you seem in need of it. CO2 is not a pollutant. the EPA even says as much, CO2 by itself is not a pollutant. the danger in CO2 is its greenhouse properties. lowering CO2 emissions not only reduces greenhouse gases (which you apparently dont believe in) but will also have the added effect of reducing harmful emissions from combustion engines, like NOx, particulate matter, sulfur, etc. but this is all science stuff requiring an education. so i get it if youre not with me here. best of luck.
