摘要：Tropical deforestation is of growing concern to the world community. Global effects associated with this process include loss of biodiversity and changes in the carbon cycle. Although the importance and present severity of these two externalities are subjects of intense controversy, few would deny the catastrophic nature of their potential impacts. Deforestation also poses local and regional problems. Loss of tree coyer can destabilize the hydrologic cycle, leading to drier climate, desiccated soils, and increased flood risks in downstream areas. When poor farmers clear forest land for subsistence, they often impose substantial costs on their neighbours in the short run. Should land abandoned by these farmers prove barren and should processes of ecological succession be styrnied by edaphic conditions, an intertemporal opportunity cost arises in the long run, since possible forestry revenues and environmental protection values will be lost to future generations.
