Book excerpt: Bioregionalism asks us to reimagine ourselves and the places where we live in ecological terms and to harmonize human activities with the natural systems that sustain life. As one of the originators of the concept of bioregionalism, Peter Berg (1937-2011) is a founding figure of contemporary environmental thought. The Biosphere and the Bioregion: Essential Writings of Peter Berg introduces readers to the biospheric vision and post-environmental genius of Berg. From books and essays to published interviews, this selection of writings represents Berg's bioregional vision and its global, local, urban, and rural applications. The Biosphere and the Bioregion provides a highly accessible introduction to bioregional philosophy, making Berg's paradigm available as a guiding vision and practical "greenprint" for the twenty-first century. This valuable compilation lays the groundwork for future research by offering the first-ever comprehensive bibliography of Berg's publications and should be of interest to students and scholars in the interdisciplinary fields of environmental humanities, environment and sustainability studies, as well as political ecology, environmental sociology and anthropology.
