On May 28, 1969, two weeks after the first street fighting in connection with People's Park, there was an all-day teach-in entitled "The Politics of Ecology" at Lower Sproul Plaza on the University of California, Berkeley campus, which was broadcast live on KPFA. Speakers addressed themselves to various aspects of the Park - urban planning, ecology, politics. There was a poster series about ecology presented by Ecology Action, and the San Francisco Mime Troupe Guerrilla Band performed. This program contains excerpts of the teach-in concerning various aspects, both concrete and symbolic, of People's Park. This program was aired a year after the incident, as part of a series of programs on Pacifica Radio's KPFA-FM examining what happened that day.
The speakers on Reel 1 are Martin Brown, teaching assistant for the "Social Responsibility of the Scientist" course at University of California, Berkeley; Cliff Humphrey from Ecology Action; Dr. Thomas Bodenheimer of the Medical Committee for Human Rights; Mitchell Goodman, one of the defendants in the "Boston Five" conspiracy trial; Keith Lampe, ecology writer for the "Berkeley Barb" and co-founder of the Yippies; Allan Temko (1924-2006), architectural critic and writer; and Thomas Hoving (1931-2009), parks commissioner for New York City under Mayor John Lindsay.
