What was Green Sahara?

While modern people consider Sahara to be an extensive and prohibiting desert, for a short time in history it was actually very pleasant. From approximately 10,000 BCE to 4,000 BCE, Sahara was fresh, green and fertile, with a short dry time of approximately 8,000 to 7,000 BCE. This period in the history of the desert is sometimes known as "Green Sahara" or "Green Period". For example, the mineral deposits in the desert indicate traces of lakes and rivers, and the remains of plant and animals' life were also found in the Sahara, suggesting that the environment was again more hospitable. In 2000, the crew of archaeologists hunted on dinosaur bones encountered a cemetery in Niger and realized that they found traces of civilization that lived in Green Sahara.

Several factors have led to the creation of a green Sahara. The Sahara has been a desert for a very long time, but around 10,000 BCE the Earth's orbit has been slightly fluctuating, causing shift in the weather. The monsoons that are being designed today have moved and poured water on the Sahara where they formed the water Ú Ú Ú šeshapes. Plants settled and used humid environments, followed by animals and people who introduced living civilizations. When the weather patterns moved again, Sahara briefly returned to the desert condition before green again. About 4,000 BCE has become the release of Sahara again and is now rapidly expanding because of different factors.

It seems that two independent human civilizations lived in the Green Sahara. The first lived from approximately 10,000 BCE to 8,000 BCE, during the first period of ecological point of view and the second moved during the second green period. When people lived in Green Sahara, they left the digit of the digestion, such as hunting instruments, traces of textiles and works of art, and grave places. Several grave sites have high levels of pollen, suggesting that people were buried on flower beds.

Archaeologists continue to gather evidence of the Green Sahara and the people who live there, with a large proportion of these evidence from the extremely isolated and serious areas of the desert. These findings illustrate how tohas changed the climate of the Earth and how changes in climate can change human civilization.
