Peter Berg


Remembrances, reminiscences, recollections, tributes, rants, soliloquies, and orations, for a man who touched many lives.


40+ years of grass-roots, ecological eye-opening...

Planet Drum Foundation was founded in San Francisco, CA in 1973. In association with community activists and ecologists, Planet Drum(*) developed the concept of a bioregion. Planet Drum works to research, promote and disseminate information about bioregionalism, a grassroots approach to ecology that emphasizes sustainability, community self-determination and regional self-reliance. Through its projects, publications, speakers, and workshops, Planet Drum helps start new bioregional groups and encourages local organizations and individuals to find sustainable ways to live within the natural confines of bioregions. We believe that people who know and care about the places where they live will work to maintain and restore them.

Bioregion: a distinct area with coherent and interconnected plant and animal communities, and natural systems, often defined by a watershed. A bioregion is a whole "life-place" with unique requirements for human inhabitation so that it will not be disrupted and injured.
