Скачать или смотреть How Ancient People Survived the Sahara Desert (It Used to Be Green)

10,000 years ago, the Sahara Desert didn't exist. Where you see endless sand today, there were rivers, lakes, grasslands, and forests. Hippos swam in North African waters. People lived in green, fertile land.
Then the climate shifted. Over 3,000 years, the rains stopped. The rivers dried up. The Sahara transformed into the largest hot desert on Earth—3.6 million square miles of scorching wasteland with temperatures reaching 136°F.
But people didn't leave. They adapted. For thousands of years, ancient North Africans survived in conditions that kill modern travelers in hours. They crossed 3,000 miles of desert on foot, built trade networks connecting sub-Saharan Africa to the Mediterranean, and left behind rock art documenting their survival.
This is how they mastered the deadliest desert on Earth. And why most of their knowledge is lost.
