How do we manage our natural resources?

This 75th anniversary of the founding of our national parks finds them the focus of heated controversy over their management and use. Pollution and commercial development threaten the scenery and fragile wildlife.

This timely DVD collection showcases three of the most popular treasures: the Grand Canyon, Yosemite, and Yellowstone National Parks. These full-color DVD's blend geology, natural science, anthropology, and history.
The parks’ dramatic peaks and valleys, roaring cataracts, bubbling hot springs, and diverse wildlife have been beautifully filmed by outdoor cinematographers. A full history of each park is related, including footage from the Yellowstone fire in 1988.

Set comes in a slipcase with a background guide. Each program runs approximately 60 minutes. Grades 7-12.
