This thesis examines how particular forms of mass media spurred and guided the United States environmental movement of the 1960s and 1970s. Its objective is to better understand how mass media contributed to the evolution of the environmental movement. Three particular types of media form the basis of this study: writing (books, newspapers, and magazines), audio-visual material (movies and television), and photographs. These three mediums of communications and their intrinsic effects on the human psyche and society as a whole are major contributing factors to a raised environmental consciousness, a lasting legacy of environmentalism, and the promotion of the environmental movement itself.
