First, the context of all of this is air pollution, but that's been conflated in the most ignorant of fashions.
Second, when you don't know the difference between nitrogen (a innate gas) and nitrogen compounds used to make fertilizer, you are a Fake Sugar Dick (WARNING, NOT THE REAL SUGAR DICK!). Just like thinking that CO2 is a pollutant, even though the epa does not list it as a voc. Like 75-80% of the air you breath is nitrogen, you rough ridin' idiot.
