The Sahara Desert, the world's largest desert, was once full of greenery

The Sahara Desert , which extends to the northeastern part of the African continent, is known as the world's largest desert except for the South Pole, but it seems that the Sahara Desert thousands of years ago had a completely different sight from the 21st century. Fall of Civilizations Podcast , which distributes podcasts explaining the history of civilization, said, `` The Sahara Desert was once covered with greenery, '' and also explains why the Sahara Desert's green was lost The




Speaking of the Sahara Desert, most people recall the scene of sand covered in one side, but about 5000 years ago, the land covered with green was spreading. There are many lakes and rivers, and the early humans lived there, hunting and fishing.

This is an aerial photograph of the Sahara Desert as of the 21st century. A vast desert spreads out, and the lake that once existed has no shadow or shape.



The era when lakes and rivers existed in Sahara was also expressed as “Green Sahara” (African wet season), and the peak of the wet season was reached 9000 to 6000 years ago. Sahara, which has a gentle grassland, has a sparse forest with acacia trees.




It is also clear that the Neolithic people built a community in Sahara. In the central part of the Sahara Desert, which is now a barren land, paintings depicting rocks of many animals and swimming people have been discovered.




Most of the communities that formed the community were hunter-gatherers, but eventually cattle and sheep were bred. People observe the world around them, and the life-size petroglyphs called “Dobous Giraffes” drawn about 11,000 to 7000 years ago are said to be the largest animal petroglyphs in the world.




However, the civilization of “Green Sahara”, which is full of rich nature, will end suddenly. The Earth's precession that occurs approximately every 25,800 years rotates the Earth's axis of rotation, and the Sahara began to dry as the rainfall area moved south of Sahara about 5,000 years ago.




First of all, large trees withered, and eventually the grass withered, and the ground surface was blown away by the wind.




There are several views about how long it took for Sahara to desertify, but some believe that it took only a few hundred years for Sahara to desertify. People who lived in Sahara escaped from desertification and moved to the coast and south to establish a settled society.




The Sahara Desert is an example that reminds us that changes in the Earth can dramatically change nature and people's lives. “History is a record of change and reminds us that what we think is natural is not so natural,” concluded the Fall of Civilizations Podcast.
