Humans didn’t speed up the drying of the Sahara, and in fact they may have delayed it
Today the Sahara desert is a dry, dusty, sandy land that stretches for millions of miles, but it wasn't always this way. Go back at little as 8,000 years and you'll find it was actually quite wet, supporting countless organisms and hosting our human ancestors.
The relationship between early cattle farmers in the region and the Sahara ecosystem's eventual collapse and transition into a desert has long been a topic of debate, but a new study suggests that it wasn't humans who ushered in the death of the "Green Sahara," and they may have actually delayed the inevitable for hundreds of years.
