About five thousand years ago, the rains over the sahara began to decline and grasslands gave way to desert. the population of this region began to migrate east and south. describe how the landforms and climate of africa influenced how these people lived as they settled in new areas

Here, I just did this assignment so I got you fam. (these are just helpful

 things for you to quickly refer to) When 

the Sahara started to decline the people living there encountered the ferocious heat during the day and freezing temperatures during the night.  They wanted to move east or south to look for remaining plains or forests to live in before the Sahara became a desert it was filled with vegetation and life.  When the people moved to their new homes it most likely made them more cautious and careful with their new resources.
