An Urban Implosion
While many efforts toward conservation focus on making transportation more efficient, Paolo Soleri's urban laboratory, Arcosanti, demonstrates that biology holds the answer to our conservation woes. His alternative to urban sprawl is based on evolution and likens the cityscape to an evolving organism: "In nature, as an organism evolves, it increases complexity, and it also becomes a more compact or miniaturized system. The city too . . . must follow the same process of complexification and miniaturization to become a more lively container for the social, cultural and spiritual evolution of humankind."
