The Green Sahara! Come on

Post by mimi cici on Thu Jun 14, 2012 1:36 am

While modern humans think of the Sahara as a vast and forbidding desert, for a brief period in history, it was actually very pleasant. From around 10,000 BCE to 4,000 BCE, the Sahara was lush, green, and fertile, with a brief period of dryness from around 8,000 to 7,000 BCE. This period in the desert's history is sometimes known as the “Green Sahara” or “Green Period.”
Archaeologists have always been aware that the climate of the Sahara has changed radically throughout history. Mineral deposits in the desert indicated traces of lakes and rivers, for example, and remains of plant and animal life have also been found in the Sahara, indicating that the environment was once more hospitable. In 2000, a crew of archaeologists hunting for dinosaur bones stumbled across a graveyard in Niger, and realized that they had found traces of a civilization which had lived in the Green Sahara.
Two separate human civilizations appear to have lived in the Green Sahara. The first lived from around 10,000 BCE to 8,000 BCE, during the first period of greening, and the second moved in during the second green period. When people lived in the Green Sahara, they left a number of legacies behind, such as hunting instruments, traces of textiles and artwork, and grave sites. Several grave sites carry high levels of pollen, suggesting that people were buried on beds of flowers.

"You see,how much the Earth's climate has changed, and how changes in climate can alter human civilization"
