Tropical Africa for fuel exceeds the renewal of forest cover. The rain forests which remain in West Africa now merely are how they were hardly 30 years ago. In Guinea, Liberia and the Ivory Coast, there is almost no primary forest cover left unscathed; in Ghana the situation is much worse, and nearly all the rain forest are cut down. Guinea-Bissau loses 200 to 350 km² of forest yearly, Senegal 500 km² of wooded savanna, and Nigeria 6,000,050,000 of both. Liberia exploits 800 km² of forests each year. Extrapolating from present rates of loss, botanist Peter Raven pictures that the majority of
Geology of Liberia Geology of Liberia The geology of Liberia is largely extremely ancient rock formed between 3.5 billion and 541 million years ago in the Archean and the Neoproterozoic, with some rocks from the past 145 million years near the coast. The country has rich iron resources as well as some diamonds, gold and other minerals in ancient sediment formations weathered to higher concentrations by tropical rainfall. Two billion to 1.6 billion year old Archean and Paleoproterozoic underlie 90% of Liberia, forming the Man Shield, part of the West African Craton—a region of stable continental crust leftover from early continent formation.
