A visit with an air quality specialist at Shenandoah National Park in Virginia shows students how air and water quality is measured and how fossil fuel emissions are contributing to dangerous precipitation. Energy alternatives that result in reduced acid rain are also examined. Part of The Earth at Risk Environmental Video Series that examines the threats facing Earth and the environment.
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
