""With unerring logic and science, Kenneth Sayre dissects the origins of the ecological crisis and points to the necessary recalibration of industrial societies with the laws of thermodynamics and ecology. It is a radical book in that he gets to the heart of what ails us, and it charts a course toward a future grounded in authentic hope."-David W. Orr, Oberlin College" ""Sayre's assessment forces all seeking a sustainable future to reexamine the preeminence accorded to clean energy. Unearthed uniquely combines thermodynamics and ethics to challenge and broaden readers' understandings of the systemic issues we face. Assembled and presented with piercing clarity, Unearthed constructs a brilliant framework for making sense of our quiet but growing crises."ûFelipe Witchger, IHS Cambridge Energy Research Associates" "Kenneth M. Sayre's Unearthed: The Economic Roots of Our Environmental Crisis constitutes a major and significant contribution to our understanding of the grave ecological crisis facing humanity. It covers the complete picture, from the basic physical causes of the destruction of our environment to the sociological or anthropological forces that condition our self-destructive actions. The work not only is a brilliant and mind-sweeping piece of diagnosis and prognosis, but it goes all the way to point toward possible solutions."-Fernando Del Rio Haza, Laboratorio de Termodin b9 smica, Universidad Aut=noma Metropolitana, Iztapalapa, Mexico.
