Perspecitive on the minor roll of Car Pollution

Estimate of Pollution-
It is estimated that 100 tons per acre of wood burns in a forest fire.  Using the accepted conversion carbon to co2 that equals some 367 tons of carbon dioxide per acre.  The 2012 High Park fire in Larimer County, Colorado burned 83,000+ acres.
367*83000=30,461,000  

est pollution 30,461,000+ metric tons of carbon dioxide

US cars carbon dioxide emissions EPA-

1960- 2,550,000,000 metric tons
2010- 1,000,000,000 metric tons  

Just 1 wild fire equaling some 3% of Car Carbon Dioxide in the USA.  Add up the total number of acres burned & grass fires world wide every year that make car pollution look to be quite a minor thing.  
A much different look at Car pollution than the "Man made Climate Changers" would have you see.
