Cities in developed countries will learn sustainability from slums in the developing world



The Futurist Magazine :
"Dwellers of "slums," favelas, and ghettos have learned to use and reuse resources and commodities more efficiently than their wealthier counterparts. The neighborhoods are high-density and walkable, mixing commercial and residential areas rather than segregating these functions. In many of these informal cities, participants play a role in communal commercial endeavors such as growing food or raising livestock."
