The environmental movement has often been accused of being overly negative—trying to stop "progress." , on the other hand, is about starting things, specifically an ecological design revolution that changes how we provide food, shelter, energy, materials, and livelihood, and how we deal with waste. Ecological design is an emerging field that aims to recalibrate what humans do in the world according to how the world works as a biophysical system. Design in this sense is a large concept having to do as much with politics and ethics as with buildings and technology. The book begins by describing the scope of design, comparing it to the Enlightenment of the 18th century. Subsequent chapters describe barriers to a design revolution inherent in our misuse of language, the clockspeed of technological society, and shortsighted politics. Orr goes on to describe the critical role educational institutions might play in fostering design intelligence and what he calls "a higher order of heroism." Appropriately, the book ends on themes of charity, wilderness, and the rights of children. Astute yet broadly appealing, combines theory, practicality, and a call to action.
