Plot Summary:How do humans thrive, day after day, in nature's most extreme environments? Award-winning journalist Donal MacIntyre experiences their harsh struggles firsthand in four engrossing excursions to the farthest reaches of the world. Join MacIntyre as he lives with the Bedouins on the edge of the bas Rub' al Khali Desert, wehre the temperatures regularly exceed 120F; the Insect Tribe in the rainforest of Papua New Guinea, where men spear crocodiles by torchlight; the Quechuan Indians in the Bolivian Andes, where salt flats stretch to the horizon in thin, barely breathable air; and the Bajau Laut, landless nomads who survive entirely on boats in the Celebes Sea. Each adventure serves as a study in humans' adaptability, imagination, and indomitable will to survive.
