The combination of rapid tiuman population growth, widespread 

 poverty andan inability to put sustainable systems of agriculture

 extinction must be considered and intelligent choices made now for

"Population Growth and the Destruction of Tropical Forests" 

 Paul R. Ehrlich, Bing Professor of Population Studies,

Human population growth has major global impacts. In tropical for- 

 est regions, this growth contributes to the demand for land. It in- 

 creases the demand for forest products worldwide. Indirectly it con- 



tributes to deforestation, which may lead to global warming, ozone 

 depletion, and acid rain. What steps can be taken to protect the for- 

 ests and the earth.

 Russell A. Mittermeier, President

Plant and animal species of the tropical rain forests are being des-

 al forest habitats, examine recent extinctions and the critical need 

 for conservation efforts.
