Crap, don't even think you could get past the Process Flow, since we are a LOOOONNNNGG way from understanding all of the variables that go into making this machine we call home tick.
Gee Greg, thanks for making my point. Taking drastic, and economically catastrophic, actions to forestall a theoretical problem that we can have negligible affect upon even if the doomsayers are correct, makes little sense. Promoting panic and demanding immediate action serves an agenda, but not an environmental one.
