Most planners, landscape architects, architects and engineers have an environmental ethic as well as an eagerness to improve the wellbeing of people. The contradiction of advancing ecologically focused (ecocentric) and anthropocentric values simultaneously may explain the gap between philosophy and what we have built over the last five decades. This ethical dualism arises because the professions are hetero geneous in practice types and application
scales. Therefore, many design professionals may focus on the parcel scale and not see the cumulative impact of their work. Also, for many professionals the absence of opportunity and the lack of knowledge might explain ineffective or insufficient application of sustainable urban design. Consideration of environmental values and anthropocentric practice is clouded by a veneer of sustainability rhetoric and a focus on the site scale rather than on the larger, more important issues impacting local ecosystems. The small population of professionals engaged in the planning and design of the built environment may also dampen the expectation that individuals, or even the whole profession, can make meaningful stewardship contributions toward solving the worldwide problems of poor human health, habitat loss, species extinctions, global warming, etc.
Value systems
Ecocentric values
The ecocentric perspective posits that every species should have an equal survival opportunity.! An estimated 21-36 percent of the world's mammal species, 13 percent of birds, 30-56 percent of amphibians and 30 percent of conifers are threatened with extinction. The number of threatened species has increased in every category since 1996. In 1996, for example, 3,314 species were
