Humans aren't generally logical; we're capable of logic, but it's not our general state of consciousness. Narrative is our one, overarching "innovation" we've achieved over our nearest relatives. Narrative is a kind of data compression algorithm, if you will. By connecting facts via story, we can keep track of enormous amounts of data over a long period of time.
Tragic species enact tragic, destructive, eschatological narratives. Sustainable species enact positive, nurturing and generative narratives. If we can communicate a message that is the latter, we have a chance of survival.
