Innovative and incisive films and videotapes exist which address the issues of toxic waste, agricultural pollutants, land and water use, energy production, and other important environmental topics. They provide in-depth analyses, alternative points of view, and specific suggestions for what ordinary citizens can do to help stop environmental deterioration. Media Network's computerized information Center lists over 4,000 films, videotapes, and slideshows on social issues, extensively cross-referenced with descriptions, running times, costs, and distribution information. The films and videotapes listed in this guide represent a richly textured selection of the best available productions chosen from over 500 considered for inclusion. The subjects covered are: (1) "Agriculture and Food"; (2) "Air Pollution and Acid Rain"; (3) "Alternative Technology"; (4) "Energy"; (5) "Garbage and Recycling"; (6) "Global Crises"; (7) "Hazardous Waste and Toxics"; (8) "Indigenous Peoples"; (9) "Land Use"; (10) "Nuclear Energy and Radioactive Waste"; (11) "Organizing"; (12) "Rainforests"; (13) "Threatened Species"; (14) "Water"; and (15) "Workplace Hazards." Each entry in the guide includes the title, producer or director, length, year it was released, an evaluative description, the distributor, the cost for renting or buying, and the format (e.g., film and videotape). An alphabetical index, audience index, subject index, and a listing of distributors are appended. (KR)
