"David Orr is a treasure trove of provocative thought as he probes the treacherous fault lines leading to unsustainable communities and ecological collapse. He challenges us to tear down the walls of separation between analytical science and intergenerational love and to ponder knowledge in search of life-sustaining wisdom."
(Larry Schweiger President, National Wildlife Federation
"Orr (environmental studies and politics, Oberlin College) has assembled 35 essays he wrote between 1985 and 2000 documenting and analyzing what he calls the white-water rapids that human civilization entered during that period. The overall themes are the fundamentals, sustainability, ecological design, education, and energy and climate. Among the topics are verbicide, walking north on a southbound train, designing minds, ecological literacy, and Pascal's wager and economics in a hotter time."
"David W. Orr is obviously a very intelligent man and his essays provide rich food for thoughts for those of us who want to steer the world in a more sustainable direction."
"Orr lays out our societal blocks candidly, examines them, and then plainly and honestly states next steps. Steps that, while not necessarily easy, will help us evolve beyond current cultural constructs. This book dares you to be humble and to not react to ignorance and arrogance but rather reflect and respond with care and integrity. This book begins and ends by challenging and encouraging those who profess to lead, to teach, to do good in the world: Demonstrate your worth. Be humble, be honest, be visionary. Act. Study, love, appreciate, work with, and emulate what gives us life, purpose, connection, and beauty. There is so much more I would love to share about this book. It is totally worth your time and energy. Read it!"

"Like our other environmental heros, Rachel Carson and Aldo Leopold, David Orr's genius likes in his ability to bring together the practical wisdom of the ecological sciences, the moral clarity of ethics, and the power of incisive prose. Hope is an Imperative is a gift of enduring insight and imagination, a source of hope in itself."
(Kathleen Dean Moore author of Wild Comfort
