Hmmm... This is a very old program judging from the quality of video and audio.. I'm thinking the intent was to shed the stereotype image of Africa and it's people shared by uneducated folks of that time.
Beware of those telling the story of another people through their lenses! Regardless of how well intention-ed it may appear.
I didn't know that there was Africa and then there was Black Africa.
There is some good content there, migration, early trade routes, topography changes etc. So, Thanks for posting.
