SLAVERY.
The Slave Trade took millions of people out of Africa to the American southern colonies but also to places like Cuba, Brazil, the Carribean Islands including Haiti and Trinidad. They found themselves in trade to masters in Mexico, Central America, Northern South America and Ecuador. Some escaped and liberated slaves were able to find a life in places like Jamaica.
My point is that for as estranged as the Diaspora has become from it's heritage it is wrong and they should be given the opportunity to identify with their roots realizing the countries and communities of Africa are in need of advocacy for those that can and will.
If we are to look at Africa in detailed ways to solve it's problems and sustainability we need to look to the whole of Africa and that dictates those that were taken out of Africa against their will.
