Michael, regarding your 18:10 comment – humanity and all the nations must learn to cooperate or the entire edifice of our civilisations will fall in pieces around us and we or our descendants will die by the billions – if we don’t kill each other first, as resources run short, with our nukes and modified viruses. Despite modern ideas about progress we are dependent upon nature, not her master. Unrestrained competition would be the undoing of us.
