In light of all the AGW nonsense…

………………  there’s this:

Life is deadly. All living things that breathe oxygen burn their food and emit poisonous CO2 as a pollutant. With every breath they contribute to the concentration of CO2 in the atmosphere, and, hence, to global warming. And yet, for all the frantic formulas floating around aimed at the reduction of CO2 emissions, particularly through limitations on the burning of fossils fuels (dead living things), little attention has been paid to this obvious other source (still living things). Rough calculations suggest that CO2 emissions from the burning of fossil fuels are dwarfed by the emissions from these living things, including human beings. Emissions from human metabolism alone, assuming a world population of six billion people and an averaging of their state of activity, are estimated to be equivalent to approximately half of 1990 fossil fuel emissions. Add to these human sources the CO2 emissions from all other creatures on the planet, including plants which respire as well as photosynthesize, and the total amount of emissions from living things is staggering.” (David F. Noble and Denis G. Rancourt, Activist Climate Guy)
