THE SAHARA: The Desert That Used to Be Green | 4K Travel Documentary

👇 Everything we curated for this Sahara episode. Tours, books, cookbooks, travel resources. Six thousand years ago, the Sahara was not a desert. Hippos wallowed in its rivers and cattle herders raised families on green grassland where today there is nothing but sand. In a cave near the Egyptian border, explorers once found paintings of people swimming, made by artists who watched that green world vanish. The Sahara is not a constant. It behaves more like a clock. Over the last eight million years it has turned green and dried out more than two hundred times, driven by a slow wobble in the Earth's orbit. This is the story of the largest desert on the planet, the people and animals who survive it now, and the lush world that came before. In this documentary, discover how the Sahara greens and dries on a 21,000 year cycle, and what its buried lakes, ancient rock art, and lost desert kingdoms reveal about where it is heading next. 📚 BROWSE THE SAHARA COLLECTION Every book, cookbook, and cultural item we'd recommend for this episode → https://amzn.to/4erCBTf 🛍️ SEE OUR FULL W.O.E.
