Despite the occasional rhetoric about ecological interdependency, the response by environmental designers, architects and builders to the ecological crisis has been, on the whole, superficial. Dysfunctional human society-nature relationships remain largely unchallenged in built environment design. Eco-logical design should be as fundamental to building as structural logic is to engineering; however, this is not yet the case. Eco-logical design can be viewed as an ethic and method for achieving social transformation.
