The Scope of the "Wave"

   Here is an aerial image showing the extent of a typical sub-division. 

On my travels across the USA, I have seen examples of this sprawl everywhere! 

   Much of this sprawl has occurred in my lifetime.  I believe that is the result of a "Civilization Bubble" that will probably burst by the year 2050.  The only question is - how much of the natural World will be left when that Bubble bursts?
