Just prior to periods of great migration, certain species display agitation and restlessness - a phenomenon referred to by scientists as 'zugunruhe?. McLennan identifies a similar pattern emerging among people yearning for a sustainable future. This book is intended as a catalyst for anyone interested in exploring a deeper, more meaningful connection to the environmental movement. ?Zugunruhe is a work of creative genius that draws us into an engaging journey of self-discovery, brings the biggest and most frightening issues of our time up close, and invites our engagement,? notes David Korten, ?It will leave you envisioning human possibilities you never previously imagined.? Profound, personal and practical, McLennan?s narrative reminds us that individual efforts ripple outward and can lead to revolutionary change for the betterment of people and planet.
