29% of Earth is land mass. Of that 29% humans occupy less than 2 to 3% of that area. Of the remaining land mass, about 40% is pure wilderness. 14% is true desert and 15% has desert like characteristics. 9% is Antarctica. Most of the remaining 22% are agricultural areas.
The notion that man is causing the planet to heat up based on CO2 that amounts to 0.0314% of the gas in oxygen can only be believed by morons.
