> But destroy the world? It seems evident Earth itself would remain in it's current spherical shape but it would be terribly perhaps irreversibly poisoned, taking a lot if not all life with it. At risk of being self absorbed, if the world is largely uninhabitable and our way of life irreparably changed, then I'd consider that serious enough to lump in the "destroy the world" category. At that point I probably wouldn't care if the Earth was still an intact oblate spheroid given I'd either be dead or likely wishing I was.
