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 2 are Barry Weisberg of the Bay Area Institute; telegrams by Paul Goodman and Jane Jacobs are read aloud; Sim Van der Ryn, architect; Robert Greenway, vice chancellor for academic planning at the University of California, Santa Cruz; Gary Snyder (1930 - ), poet; and Lew Welch (1926 - 1971), poet, who reads his poem "The Song Mt. Tamalpais Sings."
