The best available analyses suggest many reasons for trying to limit the rate of deforestation, one of them being that deforestation accounts for 20 percent of the worldwide anthropogenic contribution to greenhouse warming (World Resources Institute, 1990~. Where forests must be used, the goal is to practice what is called "sustainable forestry," in which harvesting practices maintain the forests and protect soil, water, wildlife, and future resources.

EMISSION CONTROL METHODS Recently, a number of tropical forestry experts met to discuss the causes of tropical deforestation and what could be done to slow deforestation. They arrived at a number of conclusions, some of which are summarized below (Smithsonian Institution/International Hardwood Products Association, 1990~:

· Funds obtained from products of the tropical forests must be rechanneled into managing and regenerating those forests. · The international tropical timber industry should encourage the continued establishment of conservation areas solely dedicated to forest preservation.

These measures and others would provide a total carbon savings from the Costa Rican project of at least 21.8 Mt over 40 years (Conservation Foundation, World Wildlife Fund, and Fundacion Neotropica, 1988~. The cost and carbon sequestration figures from WWF's estimates are extrapolated for the present rate of deforestation in Appendix O

. The United States can act to prevent further degradation of its own forests, but in terms of affecting potential climate change, there are greater opportunities to be had in helping developing tropical countries to limit deforestation.

Unless people who work in cattle ranching, timber extraction, farming, charcoal production, and gold or oil exploration can find an alternative source of revenue compatible with their skills, their income will drop and their country's subsequent economic development will suffer. Further, growing populations maintain pressures for homesteads, farmland, traditional fuel resources, and other land-based resources.

In a broader geographic sense, it is important to understand both the variety of factors leading to deforestation throughout the tropics and the way in which countries such as the United States can contribute to solutions without challenging national sovereignty and sensibilities. CONCLUSION The causes of deforestation are many and varied and relate largely to population and economic pressures in developing tropical nations.
