Rebuilding of Cities and Worldly Management Creating True Growth

We are harvesting to much of this planet it's resources and trees..I am concerned because if it keeps going on this planet will end and there wI'll be nothing beautiful left to even be around...What I want to happen is our focus to shift onto the reality that cities are way to overbuilt and there are hundreds of millions of resources that we already have at our finger tips we need to start taken down cities and use the materials from all of the overbuilt buildings and homes we need to think of a small place big enough to keeK eat and sleep in comfortably we need to maximize the use of these already harvested resources and redesign everything into an organism so earth'ship city that interconnects with free power and water catches built on to them also make it one big livestock and natural resource devolving machine to save on everything
