The Berlin Conference was the destruction of Africa in more than one sense: the colonial powers divided the countries of the African continent; When independence progressively returned to Africa in the second half of the 20th century, the continent had such a degree of political, social and cultural fragmentation that it has not yet been able to rise.
At the time of the conference, 80% of Africa remained under local control. What ultimately resulted was a hodgepodge of geometric boundaries that divided Africa into fifty irregular countries. This new map of the continent was superimposed on the thousand cultures and indigenous regions that existed. The new countries lacked cohesion, divided coherent groups of people and merged disparate groups that did not really get along.
Bill Clinton is the answer :)
The most important environmental problems in East Africa / Horn of Africa are overgrazing, deforestation, water shortages, loss of biodiversity, and urban-industrial pollution. While environmental laws exist in most countries of the region, there is often inadequate implementation.
