Book excerpt: The complexity and scale of the environmental problems confronting humanity today provoke a wide range of responses, from indifference to anger to creativity. Among a growing number of architects, landscape architects, and planners, however, these problems have inspired a new vision-sustainability-to guide their practices. In Nature, Landscape, and Building for Sustainability, a diverse group of contributors considers the concept of sustainability, both philosophically and practically. Some take a broad view of the divisions between nature and humanity, exploring the incomprehensible scale of human intervention in the natural world, the relationship between how we feel about nature and what we do about it, and the commodification of the natural world. Other essays focus on sustainable design practices: sustainability's roots in the American conservation tradition, its utility as a framework for future design practice, and the necessity of moving beyond demonstration projects into the mainstream. Together, these essays suggest that the gap between the promise and reality of sustainable design, although significant, can be bridged through diligence and practice. Contributors: D.
