An examination of the extinction threat faced by frogs, which have hopped on Earth for some 250 million years and are a crucial cog in the ecosystem. Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.

"The acid soil of New England, its wide stretches of hardwoods, its numerous sugar maples, its rolling or mountainous character, the sunshine of its autumn weather, all these contribute to the glory of this annual display. The birches of Maine the aspens of the White Mountains, the sugar Maples of Vermont, the long rainbow of the Connecticut River Valley cutting from top to bottom through New England, the Berkshires - mention these to anyone who has traveled widely through a New England fall and you will evoke instant memories of superlative beauty." -Edwin Way Teale, Autumn across America, 1956
