The Earth was made from hot rocks, gasses, reactions, explosions etc, of sizes beyond what we can comprehend. If all that shit hadn't happened we wouldn't fucking be here to argue the toss about the impact our own activity is having because of a few chimneys.

I would say these people are stupid, but that's too easy. They're megalomaniac psychotic transhumanist demon freaks who want the planet for themselves for their Saturnalian orgy of kid-raping, sacrificing and eating that they genuinely think will make them live forever.
