600,000 by 1990. Forest elephants are being hunted in increasing numbers now, and their population in Western Africa has been reduced to under 3,000.
When European powers established colonies in Africa, they sought to exploit the continent's natural resources. In Eastern Africa, the British sought to extract the raw materials present and grow other goods useful to the empire.
One major problem for Africa in the 20th century has been desertification, the

Forests have also been heavily destroyed. By the 1980s, as many as nine million acres of African forests were being cleared annually. The countries hardest hit include the Ivory Coast, Nigeria, Liberia, Guinea, and Ghana.
