Recents concern about the impact of global warming upon the world's climates and increased pollutiion and despoilation of natural habitats have introduced the concept of environmental and ecological sustainability as a criterion against which to judge all human activity. Sustainable design and urban and regional planning is the philosophy of designing and planning the human-built environment to comply with principles of economic, social and ecological sustainability. Originally first articulated as a criterion for urban design and planning back in the 1970's by Richard Hopper (then Hawaii's State Environmental Planning Coordinator) both in an article published in the magazine of the American Planning Association and as part of an effort he led to develop a "Quality Growth Policy for the State of Hawaii," sustainability is no longer a concept limited to the field of biology. Instead, as Hopper articulated back in the 1970's all natural and man-made systems have an inherent carrying-capacity that can either be: (1) used as a limit for growth; (2) ignored and exceeded with the consequence of thus degrading the system; or (3) expanded through new technologies and method of design and planning. As such, applying the concepts of sustainability and carrying-capacity to the design of our man-made built environment helps to protect the quality of both our man-made and natural environment.
