But it was once beautiful, green and fertile place. Scientist belive that around 10,000 B.C., the Earth's orbit wobbled slightly, causing a shift in weather patterns. The monsoons which drench Southern Africa to day shift up, pouring water into the Sahara, where it forrmed bodies of water. plant life flourished and plants were followed by animals and humans, who established lively civilizations. When weather pattern shifted again, the Sahara turned to being a desert once more.
