Question

in north africa, overgrazing has contributed to which environmental challenge? (1 point)
deforestation
desertification
lack of clean water
climate change

Explanation:

Overgrazing removes vegetation cover. In North - Africa's arid and semi - arid regions, this exposes soil to erosion and leads to land degradation, a key factor in desertification. Deforestation is mainly about tree removal, lack of clean water is more related to water sources and pollution, and climate change is a broader global phenomenon not directly caused by overgrazing alone in this context.

Answer:

B. desertification
