29% of Earth is land mass. Of that 29% humans occupy less than 1% of that area. Of the remaining 28% 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. There may be other areas with a human footprint of some kind.
The notion that man is causing the planet to heat up based on CO2 that amounts to less than 1% of the gas in oxygen can only be believed by morons.
