Sahara Wildlife Collapse

The Sahara desert is experiencing a "catastrophic collapse of its wildlife." "Of 14 species historically found in the Sahara, four are now extinct, and the rest are heading that way.... the region has lost the Bubal hartebeest (which is entirely extinct), the scimitar horned ornyx (extinct in the wild), the African wild dog and the African lion, while the dama gazelle, addax, leopard and the Saharan cheetah have been eliminated from 90 percent or more of their range."
