Carbon tax is hilarious to me, the third world is burning all of the trash they don't send down river into the ocean and are absolutely ravaging the world and idiot Europeans are okay with being fleeced for flying mass transit or driving a fuel efficient car. The only carbon tax I'm okay with is private jets - not because carbon taxes make any sense, I'm just fine with arbitrarily taxing the rich. Carbon dioxide makes plants grow faster and the world has historically had higher levels than it has now. It is not a pollutant. People are fucking stupid.
