What is biological diversity and why is its preservation so vital to our future? Those critical questions are answered in compelling yet easily comprehensible terms in this powerful National Science Foundation-funded series. In three beautifully photographed programs, narrator Merlin Olsen takes viewers on an eye-opening journey of discovery, revealing the astonishing patterns of interconnection and interdependence that characterize the natural world. Along the way, leading biologists, including Paul Ehrlich and Peter Raven, disclose the latest scientific insights into biological diversity and the role it plays in maintaining the long-term health of our planet. At the same time, farmers, ranchers, and other concerned citizens share their thoughts about the kind of stewardship that will be necessary to protect biodiversity in the 21st century. An engaging and thought-provoking anchor for Earth Day-related programming.
