Book excerpt: Gardeners are the front line of defense in our struggle to tackle the problems of global warming, loss of habitat, water shortages, and shrinking biodiversity. In The New American Landscape, author and editor Thomas Christopher brings together the best thinkers on the topic of gardening sustainably, and asks them to describe the future of the sustainable landscape. The discussion unfolds from there, and what results is a collective vision as eloquent as it is diverse. The New American Landscape offers designers a roadmap to a beautiful garden that improves, not degrades the environment. It’s a provocative manifesto about the important role gardens play in creating a more sustainable future that no professional garden designer can afford to miss.
