Often thought of as nature at its most elusive and chaotic, the wind is actually a function of highly regimented patterns—forces within the Earth’s atmosphere that have shaped the destiny of continents and lie at the heart of some of the greatest turning points in human history. This program travels to stunning locations in the Sahara desert, on the coast of West Africa, and among the currents of the South Pacific to show how people have exploited the power of the wind for thousands of years. In the process, the film sets sail on one of the fastest racing boats ever built as it explores our turbulent relationship with nature’s invisible, unstoppable invader. A BBC/National Geographic-U.S. Co-production in Association with ZDF. Part of the series How Earth Made Us: The Untold Story of History. (50 minutes)
