Are you kidding! Look, the Atmosphere is 78% Nitrogen, 21% Oxygen, 1% "Other". Of that 1% Other, 3% is CO2. If you look at contribution sources of that CO2, something like 95-97% comes from natural sources, and the rest comes from people. Clearly this 3-5% human contribution of C02 since the 1940's is responsible for the destruction of the ice caps and the earth. I don't know how you can look at those numbers and deny humanities huge impact on the environment. You must be a communist baby seal hater or something!
