Final answer:
The Columbian Exchange resulted in the destabilization of African communities and decline of traditional industries due to the trans-Atlantic slave trade and introduction of European goods.
Step-by-step explanation:
An effect of the Columbian Exchange on Africa was the profound impact on West African communities, particularly through the disruptive and exploitative nature of the trans-Atlantic slave trade. Domestic industries, such as the traditional textile production and metalworking, faced decline due to the influx of European goods, which were often bartered for enslaved Africans. This trade not only harmed African economies but also led to societal destabilization, as warfare and slave raids became common to meet the demands of European traders, further leading to loss of population and displacement of societies.
