The lie of 'carbon' pollution

Scientific illiterates like Barack Obama love to complain about 'carbon' pollution, a propaganda term  that  brings to mind charcoal, soot, coal,  and other dusty black stuff. The 'carbon' they are referring to, of course, is carbon dioxide, a colorless, odorless gas that is an essential to all plant life,  enabling photosynthesis, the  natural process by which all plants turn sunlight into nutrients,  feeding both themselves and us, while excreting life-giving oxygen as a byproduct. Our lives depend on it.
