This unique title draws together in one volume some of the best thinking to date on the pressing social and environmental challenges we face as a society. These are the Top 50 Sustainability Books as voted for by the University of Cambridge Programme for Sustainability Leadership's alumni network of over 3,000 senior leaders from around the world. In addition to profiles of all 50 titles, many of the authors share their most recent reflections on the state of the world and the ongoing attempts by business, government and civil society to create a more sustainable future. Many of these authors have become household names in the environmental, social and economic justice movements - from Rachel Carson, Ralph Nader and E.F. Schumacher to Vandana Shiva, Muhammad Yunus and Al Gore. Others, such as Aldo Leopold, Thomas Berry and Manfred Max-Neef, are relatively undiscovered gems, whose work should be much more widely known. By featuring these and other seminal thinkers, The Top 50 Sustainability Books distils a remarkable collective intelligence - one that provides devastating evidence of the problems we face as a global society, yet also inspiring examples of innovative solutions; it explores our deepest fears and our highest hopes for the future. It is a must-read for anyone who wants to tap into the wisdom of our age.
