The article's author hints that the world will be saved by plant-eating hippies in hybrid cars (preaching to his choir). But in fact he is lying to them. Their hybrid car will be uneconomical under his plan, and heating their homes will be a luxury. They will only be able afford a cramped and cold city apartment next to a bus line, but even that won't work ultimately. No, his followers must die to save the planet nothing less will work.
So he is a mass murderer at heart or just a clueless tool of the real mass murderers.
