In this book, M. Jimmie Killingsworth and Jacqueline S. Palmer have a twofold purpose: to analyze the patterns of rhetoric used in written discourse about environmental politics and to make a practical contribution to the art of rhetorical criticism through the study of rhetoric in use.

The language, professional objectivity, and research programs of scientists insulate these best-informed citizens in enclaves of specialization, limiting access to crucial information and hindering effective reformative action. Science, the authors stress, is not merely a database to rely upon but a view of the world that must be broadened in order to affect social morality. Science-based activism must arise to ensure the care and future of the environment.

Killingsworth and Palmer argue that for grassroots activism to be tied to this globally conscious philosophy, a rhetoric of sustainability must be cultivated.
