the accomplishments of African civilizations have been up scared mostly because of slavery and skin color. What mean by this is that because slavery has been around for so long in places like Africa, whenever a huge accomplishment is made it's not really shown in society because everyone wants to avoid a place like that and that's why think people mostly avoid it. we can sustain these accomplishments in their impact. I think we can do this by making any accomplishment big. talking about it, sharing it with friends. Make it seem like it's not something weird made from "Africa" and make it seem like something cool that was just- made.
