Here is a summary of the passage:

Tribalism, stemming from the derogatory term "tribe" used for Africans, is a system of strong allegiance to one's ethnic group, often resulting in favouritism, conflict, and unequal treatment, akin to racism. It divides societies along ethnic lines, influencing access to resources and power, and has significantly undermined unity and development in Africa since independence. This issue is a global problem, rooted in a hierarchical view of human values, and impedes collective action on universal challenges like climate change. Effectively addressing tribalism requires a comprehensive approach, including education to uncover its historical roots and foster unity, alongside frameworks such as the Structured Cognitive Behavioral Training (SCBT) which targets unconscious biases and systemic disparities through a systems thinking approach.
