“This book is for you, and for all people who are interested in social change and open to the possibility that each of us can contribute to a “quantum leap” to sustainability. It’s also for people who are concerned about the state of the world and may be feeling a deep anxiety about the future. Above all, it is a book about mattering, especially about how we translate the abstract idea of “matter- ing” into large-scale systems change that is not only rapid and effective, but also equitable, ethical, and sustainable.” (p. 1).
