Nearly two-thirds of West Africa’s remaining rainforests are in the small but troubled nation of Liberia. That is a small miracle. A decade ago, Liberia’s forests were being stripped bare by warlords to fund a vicious 14-year civil war that left 150,000 dead. In 2003, the United Nations belatedly imposed an embargo on Liberian “logs of war.” Revenues crashed and, coincidentally or not, the war swiftly came to an end.
