Subject: Green Requires CO2

Does it strike anybody as strange that carbon dioxide -- which is present at a level of about 5% in the
air we all exhale and is absolutely necessary for the growth of green plants on which all animal life on
earth ultimately depends for food -- is designated as a pollutant?

Will we need to purchase "carbon credits" to keep breathing? Since water is an even more powerful
"greenhouse gas" will that be next? Have we entered "Wonderland" and not noticed?
