It was some eight thousand years ago when glaciers chilled northern Europe, the Sahara desert was fertile and well-watered land. This vast area was once very fertile grassland. But then something happened. As a result, the lush green area of Sahara turned out to be a desert. Even today, there’s enough evidence to show that the Sahara desert had once a grassland ecosystem and was much wetter place than it is today. The discovery of ancient cave drawings in parts of the Sahara proves that there used to be green and thriving vegetation.
