crazy :O
I have no idea what humanity will do to deal with it's shit. It's a natural fact that every living organism produces shit, and most industrial systems produce "shit". For modern society even things that aren't "Shit" become "Shit", and things that aren't shit aren't necessarily designed to bio-degrade! Anything that functions pretty much produces shit. When you have millions upon millions of people producing shit and forcing it into ecological systems that couldn't possibly naturally get rid of it you get too much shit ,and then problems.
Really i think modern society is still so much like a child/animal, we fight other children over toys/food and not only that but we still shit our diapers. we think we can sweep it under a rug but that shit still stinks
when it comes down to it the only solution is self-sufficiency, rather than this mass, societal sufficiency.
