Our natural resources are finite. The current practice of designing without regard to the natural environment has resulted in an economically and politically irresponsible reliance on fossil fuels; it has produced artificial environments whose lack of fresh air and natural light, and use of materials containing toxins, has resulted in increased “sick building syndrome“ illnesses and a decrease in worker productivity; its disregard for waste has resulted in polluted waters and skies, weakening the natural habitat and allowing foreign predators to invade; its land use practices and reliance on personal modes of transportation have resulted in longer and more frustrating commute times for workers and an increasing disparity among economic classes. These policies were not intended to harm the environment or reduce the quality of life; they are a naïve carryover from a time when our abundant resources were thought limitless and when an unprecedented economic prosperity generated a sense of immunity from environmental problems. Only now are the consequences beginning to be felt, as the economic “bottom line“ becomes affected and as recent world events lead us to question our independence on foreign sources for energy.
