The Sahara Spread out over 9 million square kilometres across north Africa, the great Sahara desert is the largest sand desert in the world with a remarkable variation of microclimates and communities of plant and animal species. From the Red Sea in the east to the Atlantic Ocean in the west, the Sahara morphs from vast stone plateaus to areas of undulating sand dunes, punctuated by deeply cut mountain ranges and small green oases. Despite the harsh conditions, the Sahara is home to an estimated two million people formed of permanent communities that have set up close to water sources and the ethnic tribes that live a traditional nomadic existence following ancient trade routes. Most famous of these tribes are the Berbers, descendants of the pre-Arab inhabitants of North Africa, who even after some 4,000 years maintain their own language and culture across the Sahara and much of Morocco.
