It should be no news to anyone that all living things emit carbon dioxide as part of their life processes.
Natural processes produce much more than industrial processes.
A forest fire, for instance, can produce more carbon dioxide in days than a coal-powered power plant would in decades. Also, carbon dioxide is not toxic. The advocacy agenda is, as always, to use the environment as a lever to increased power in regulatory agencies, not necessarily those responsive to the American voting public. Devious scientific studies and pronouncements have elevated carbon dioxide into a basis for the Kyoto protocols, submission to which would transfer to international bodies devastating authority over our domestic energy, manufacturing and transportation industries. Industrially developed nations, particularly the United States, would find their development successes to be targets of their economic competitors everywhere, but particularly in all the Third World countries.
