Part manifesto and part practical guide, Urban Green: Architecture for the Future by Neil B. Chambers (2011, Palgrave Macmillan) offers an alternative plan for practicing sustainable design from the ground up. Chambers, who also blogs for Treehugger.com, advocates looking to nature for the missing components of the green revolution. He explores how many of the problems facing us today have solutions found in nature, ranging from oysters that filter water to beavers that enrich the ecosystems. He explains to readers how ecologists and environmentalists are joining with architects and city planners to make the natural world a part of cities. Chambers encourages everyone to do their part to restore the natural world and gives tips on how to do so. Chambers is an award-winning green designer and founder of Chambers Design INC. and Green Ground Zero. The book is $28 and can be purchased online at amazon.com or at local book retailers.
