Earth's Frontiers

SHOW #4

Biodiversity

Biodiversity is the variety of life on earth at all levels: from genes, to species, to entire ecosystems. But what happens when those ecosystems are jeopardized by humankind's desire for economic growth? Should biodiversity be sacrificed in the name of progress? And once gone, can biodiversity ever be restored? From the jungles of the Amazon to the shores of the Aral Sea, Earth's Frontiers explores the conflict between progress and preservation.
