Nature will always prevail, our universe is made of Nature, natural forms of life, not technology.  This temporary technological global civilization will pass, will fall for as-yet undetermined reasons, and it'll be back to normal soon enough.  Technological humans came about a moment ago, even in terms of just earth's history, and that moment will pass and Nature will still be here.  City people are so out of it, because it's all they experience they think man-made is the basis of the universe.
