As little as 6,000 years ago, the vast Sahara Desert was covered in grassland that received plenty of rainfall, but shifts in the world's weather patterns abruptly transformed the vegetated region into some of the driest land on Earth. They constantly move around to find new areas to graze their livestock and hunt for food. Trade routes across the Sahara Desert were an important part of the economies of Ancient Africa. Goods such as gold, salt, slaves, cloth, and ivory were transported across the desert using long trains of camels called caravans.
