E.O. Wilson (The Diversity of Life, Cambridge, Mass.: Belknap Press, 1992) estimates that 95% of the planet's species remain undescribed and at the rate we are progressing it would take nearly 4000 years to describe all the species on Earth.
Dietz, James M. ("Conservation of Biodiversity in Neotropical Primates," from Biodiversity II, Reaka-Kudla, Wilson, Wilson, eds. Washington D.C.: Joseph Henry Press, 1997) notes that since 1990 four new primate species have been discovered in Brazil.
The complexity of interactions within ecosystems is summed up in an eloquent fashion by E.O. Wilson in Consilience: The Unity of Knowledge (New York: Alfred A. Knopf, 1998). Ecologists have attempted to simplify their understanding of these systems by linking biodiversity and ecosystem function through defining membership in functional groups as explained by Silver, W.L., Brown, S., and Lugo, A.E., "Effects of changes in biodiversity on ecosystem function in tropical forests," Conservation Biology Vol. 10 No. 1 (17-24), Feb. 1996.

An overview of biodiversity and ecosystem valuation is presented in Wilson, E.O., The Diversity of Life, Cambridge, Mass.: Belknap Press, 1992. Wilson argues that by putting a price on the goods and services biodiversity provides we may be able to reduce uninformed destruction of species and ecosystems.

Inamdar, A., H. de Jode, K. Lindsay, and S. Cobb in "Capitalizing on Nature: Protected Area Management," (Science 283: 1856-1857, March 19, 1999) suggest that a business-oriented approach to biodiversity conservation may be the best way to strengthen existing conservation institutions.
The merits of community-based conservation are reviewed in Western, D., Wright, R.M., and Strum, S. eds., Natural Connections : Perspectives in Community-Based Conservation, Washington, D.C.: Island Press, 1994 (a series of case studies); Fimbel, C. and Fimbel, R., "Rwanda: The role of local participation." Conservation Biology Vol. 11 No. 2 (309-310), Apr. 1997 (case study in Rwanda); and Getz, W.H. et al., "Sustaining Natural and Human Capital: Villagers and Scientists," Science 283: 1855-1856, March 19, 1999. Hackel, J.D. ("Community Conservation and the Future of Africa's Wildlife," Conservation Biology, Vol. 13, No. 4: 726-734, August 1999) discusses some of the conflicts between community-based conservation and the economic needs of local Africans.
Kremen, C. et al. ("Designing the Masoala National Park in Madagascar Based on Biological and Socioeconomic Data," Conservation Biology, Vol. 13 No. 5 (1055-1068), Oct. 1999) note the importance of considering human use of forest areas prior to designating a protected area.
Noble, I.R., and R. Dirzo, "Forests as Human-Dominated Ecosystems," Science 277: 522-525, July 25, 1997 argue that it is important to recognize that today many forests are human-dominated ecosystems used for logging, hunting, and agroforestry. The emphasize the need to develop strategies for sustainable management and to encourage interaction between all interested parties.
Costa, P.M. ("Tropical forestry practices for carbon sequestration: a review and case study from southeast Asia," Ambio Vol. 25 No. 4, June 1996) examines tradable greenhouse gas emission budgets including some of the hurdles such a system must overcome. Rippel, B. ("Tradable CO2 Emissions Permits: Problems with the 'Perfect' Solution," National Consumer Coalition 11/25/97) points out that because some countries already have emissions below their 1990 levels, they will be able to sell their credits to countries with growing economies, essentially being rewarded for running polluting and inefficient industries. Daly, H. (Beyond Growth: The Economics of Sustainable Development, Boston: Beacon Press, 1996) notes the scale problems of tradeable pollution permits in that there will always be pressure to exceed self-imposed limits on carbon emissions.
Costa, P.M. ("Tropical forestry practices for carbon sequestration: a review and case study from southeast Asia," Ambio Vol. 25 No. 4, June 1996) and Asumadul, K. ("Carbon trading: a new opportunity for tropical timber producing countries," ITTO Tropical Forest Update Vol. 8, no. 4, 1998) discuss carbon offset programs based on the idea that forests can serve as net carbon sinks. However, recent studies (B. Scholes, "Will the terrestrial carbon sink saturate soon?" Global Change NewsLetter (the International Geosphere-Biosphere Programme-IGBP) No. 37:2-3, March 1999) and R. Watson et al. IPCC Special Report on Land Use, Land Use Changes, and Forestry, the Intergovernmental Pannel on Climate Change, 1999) dispute this claim. They suggest that as temperatures rise, respiration rates will increase, eventually canceling out the carbon absorbed by forests growing today.

EDF (Making the Label Stick, The Environmental Defense Fund, 1997) and Myers Myers, N. ("The world's forests: problems and potentials," Environmental Conservation 23 (2) p. 158-168, 1996) believe that eliminating subsidies for activities that promote forest clearing would probably have the widest ranging effect on curbing deforestation in the tropics.
According to Hurrell, A., ("The politics of Amazonian deforestation," Journal of Latin American Studies 23: 197-215, 1990) the Amazon was thought to have great investment potential.
MacNeill, J. ("A commentary on the politics of prevention," in Tropical Forests and Climate, N. Myers, ed. Dordrecht: Kluwer Academic Publishers, 1992) notes that there are serious conflicts of interests within government departments in many developing countries (MacNeill 1992)
Daily, G.C., Ehrlich, A.H., and Ehrlich, P.R., ("Socioeconomic Equity: a Critical Element in Sustainability." Ambio Vol. 24 No. 1, Feb 1995) note that poor nations have little incentive to cooperate in maintaining the lifestyles of the rich through conservation efforts while they remain mired in poverty.
