This study by Andrew Kirk shows how the issues surrounding American environmentalism have changed from an either/or conflict of pristine wilderness vs. nearly out-of-control development just after World War II, to our present post-Whole Earth Catalog/Internet-powered regime whereby we can negotiate the peculiarities of our immediate environment and understanding of such with our much easier access to ideas and appropriate technology. Each individual human being, along with his or her tools, can now, for good or ill, dare be seen as part of the natural environmental process itself.
Counterculture Green is well written and will be especially informative for those such as myself who have not kept in close touch with the details of the environmental movement overall, nor with the Whole Earth phenomenon over the years, and who now feel compelled to learn more about the ideas and activities that have shaped our world during and after the catalytic decade of the 1960s.
The books, From Counterculture to Cyberculture by Fred Turner, and Whole Earth Discipline by Stewart Brand, are excellent additional resources related to Counterculture Green.
