Publication of Friends of the Earth, published mid-April, 1975.   Tabloid primarily focused on the dangers of nuclear energy and technology, and how the proliferation of nuclear reactors can be fought and opposed.  A wide range of articles addressing environmental threats, however, including the threats posed by the looming launch of supersonic flight (Concorde).   A fascinating look back at what environmentalists wrung their hands about in the mid-70s.   20 pages.
