arcology
"In nature, as an organism evolves it increases in complexity and it
also becomes a more compact or miniaturized system. Similarly a city
should function as a living system. Arcology, architecture and ecology
as one integral process, is capable of demonstrating positive response
to the many problems of urban civilization, population, pollution,
energy and natural resource depletion, food scarcity and quality of
life. Arcology recognizes the necessity of the radical reorganization of
the sprawling urban landscape into dense, integrated, three-dimensional
cities in order to support the complex activities that sustain human
culture. The city is the necessary instrument for the evolution of
humankind." —Paolo Soleri
