This book takes a fresh look at the many individuals and organizations who worked in the 1950s, 1960s, and 1970s to construct a philosophy of pragmatic environmentalism in the pages of The Whole Earth Catalog. At a time when many of these ideas were seen as heretical to a predominantly wilderness-based movement, Whole Earth became a critical forum for environmental alternatives and a model for how complicated ecological ideas could be presented in a hopeful and even humorous way. It also enabled later environmental advocates like Al Gore to explain our current "inconvenient truth," and the actions of Brand's Point Foundation demonstrated that the epistemology of Whole Earth could be put into action in meaningful ways that might foster an environmental optimism distinctly different from the jeremiads that became the stock in trade of American environmentalism.
