PRODUCT SUMMARY
This title is still available for purchase, however we recommend the completely new DVD title Soil Quality from the Environmental Science for Students DVD series which is also from Schlessinger Media.
Earth is the source of all life, water and climate, and this program uncovers the many ways in which humanity has been abusing it. From clearcutting and logging to toxic pesticides, parts of the planet are rapidly losing topsoil and turning to desert. This program examines the composition of topsoil and microorganisms that live there. The Earth at Risk Scholars sample soil to measure its damage and explore ways to preserve topsoil by using fewer pesticides and fertilizers, emphasizing the need for a policy from the global community to preserve land and control agricultural practices in order to reduce erosion, harmful irrigation and desertification. 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
