Ecology of the Coral Reef

This program looks at the ecosystem of coral reefs. It examines the natural disasters that threaten them, like severe storms, or the proliferation of a species like the starfish, which is ravaging the Australian Barrier Reef-perhaps a natural event, ...(more details)
 
Wetlands and Pinelands

This program is devoted to a study of wetland ecosystems, from the Pine Barrens of New Jersey to areas of Mexico and Belize, where government regulation and environmental planning are recognizing the role of humans in the ecosystem-demonstrating that...(more details)
 
Life in Arid and Semi-Arid Lands

This program explains what a desert is, why it occurs, what kinds of plant and animal life it sustains, and how that life is adapted to-or adapts to-the lack of water. The primary focus is on the effects of growing populations in arid or semi-arid re...(more details)
