>People are scared by the carbon dioxyde they exhale What is that supposed to mean? That it is somehow safe just because we exhale it? We cannot live without drinking water, but if you drink too much of it , you would die. http://en.wikipedia.org/wiki/Water_intoxication http://en.wikipedia.org/wiki/Water_intoxication So it is possible that releasing CO2 by burning huge amounts in huge amounts in the air may be changing climate. I am not arguing that it is, but arguing against "we should not be scared because we exhale it". >while they eat polychlorinated biphenyl and a thousand more toxic chemical compounds on a daily basis. Sure, but they don't come close to what climate change can do. If they can be linked to mass deaths, I am sure people will get more scared of those than they are now. Back on topic, Is the statement "It must be safe because exhale it" deserving of equal airtime?
