From the Preface:
This book is not about “sustainability.” In some ways, it is about the opposite of sustainability, about what happens when we fail to achieve a sustainable state within the grace period that nature gave us for this purpose. Nor is this book about saving the planet; instead, it provides suggestions for moving forward after we’ve realized that humanity may already have caused more damage than nature can fix on human time-scales. For decades, scientists have been warning us that bad things will happen unless we change course. This book doesn’t repeat that warning; instead, it is about what educators can do now, given that we did not change course and that bad things have already started to happen. As such, this is not the book that I wished to write, but it is definitely one that needed to be written.
