There's a part of Brazil that was almost all rainforest until the 1970s, and over the next few decades a million people moved in, cutting down the forest and building towns and cities. Monte Reel was the South American correspondent for the Washington Post in the mid 1990s, when he started hearing rumors of a "wild man," the last member of a tribe, who lived completely alone in this area's remaining forest. Reel's book about the quest to find and save this man is called The Last of the Tribe. The book also has a video trailer. (14 1/2 minutes)
