Takes readers on Dinerstein's unlikely journey to conservation's frontiers, from early research in Nepal to recent expeditions as head of Conservation Science at the World Wildlife Fund. We are there as the author renews his resolve after being swept downstream on an elephant's back, tracks snow leopards in the mountains of Kashmir with a remarkable housewife turned zoologist, and finds unexpected grit in a Manhattanite donor he guides into the wildest reaches of the Orinoco River. The book presents a cast of free-spirited characters uncommonly committed to-and remarkably successful at-preserving slices of the world's natural heritage.
