Tropical forests form the most diverse and complex ecosystem on earth-a virtual powerhouse of evolution-containing 40 percent of all living species. They provide us with food, medicines, germplasm stocks to replenish our crops, and new types of energy sources. It is clear we cannot afford to lose our tropical forests. But we are losing them-to the overexploitation of multinational corporations, to the severe economic needs of the Third World, and to the consumerist appetites of the developed nations. Where is this happening and why? The answers to these critical questions are set forth eloquently by Norman Myers, one of the world's leading experts on the environment and the author of The Long African Day, The Sinking Ark, and A Wealth of Species. Dr. Myers delineates the scope of the problem and offers a blueprint for its solution.
