EDITORIAL REVIEWS

...The Earth at Risk series is highly recommended...Editor's Choice." - Video Librarian"The videos present up-to-date facts about the topic with charts, computer graphics, statistical facts, and interviews with environmentalists and other scientists. Each program moves quickly and smoothly from segment to segment; the segments featuring teenage students will especially appeal to teen viewers who will be able to duplicate the experiments themselves." - School Library Journal
