Do you know that the most dangerous and plentiful greenhouse gas is water vapor? Methane in the atmosphere is eventually oxidized, producing carbon dioxide and water.
Since termites alone, produce 10 times the CO2 of all fossil fuel burning, and all natural sources of CO2 combined are about 29 times that produced by all of man's (anthropogenic) fossil fuel burning and prescribed forest burning combined, there is one question that must be asked before creating regulation, or increasing taxation, on our ever-shrinking productive sector. How many poor people is it worth killing in the process, and how sure are we that the result produced will have any significant impact whatsoever on the environment?
