Dark days for America?What stupidity.That Paris agreement would have put the U.S.economy in handcuffs with all of the anti carbon crap in it.
The human race cannot exist without producing carbon based materials or emitting carbon dioxide gasses.Its impossible.
We humans need carbon dioxide dissolved in our blood to be a substrate for the urea cycle biochemical reaction in our blood.This cycle converts protein derived ammonia (which would eventually kill us) to urea...which is much less toxic and then we excrete the urea. We need carbon dioxide. Hail carbon dioxide.
