                         906 784.4 Sq. Km). Focus is given on forest depletion rates for 
                         the Legal Amazonia based on the analysisi of deforestation rates 
                         available in the last thirteen years. Deforestation measurements 
                         are contrasted with mathematical deforestation projection 
                         published elsewhere wich mainly assume axponetial rates of forest 
                         depletion. The study shows that up to the year of 1988, 251 429.55 
                         Sq. Km of the Legal Amazonia have been deforested, this is 
                         equivalent to 5.12 of the area of the Legal Amazonia and does not 
                         include very old deforestation values for the Para and Maranhao 
                         State. If one assumes a linear deforestation growth and uses the 
                         highest deforestation rates observed in the last thirteen years in 
                         the Legal Amazonia one should expect a projected value of 272
