Quote:If you seriously want to question the toxic effects of CO2 on the human body, you might want to take it up with Wiki.Actually, I'm very familiar with the narrow parameters that sustain life on the planet. Small variations in atmospheric composition, temperature or pressure would threaten all life as we know it. Even oxygen, in fact, would become toxic in a 1/3 higher than our current (~20%) concentration at sea level pressures. So, then should the government regulate oxygen as a possible pollutant?
