||Only in four out of the original 25 nations [in Africa] are [chimpanzees] found in significant numbers, and even there the remaining populations are being increasingly fragmented by habitat destruction.

And, as forests are clear-cut, so the soil becomes infertile, water tables drop, deserts take over.
