The forest removal is a major contributor to local, regional and global environmental changes. Many of the tropical`s species are gravely threatened Numerous studies suggest that from 1970 to 1990 between 5 and 20 percent of the tropical`s species were committed to extinction. In 1995, the deforested lands in Brazilian Amazon account an amount Superior to 470,000 Km{sup 2}, old deforestation included, for a total surface of tropical`s rain forest of 3.4 and 3.8 million square kilometres. In 1990`s, the amount of carbon released to the atmosphere (as CO{sub 2}) from Brazilian Amazon deforestation was 3.5 % to 4.9 % and 250 % to 360 % of the World and Brazilian annual emission from fossil fuels, respectively. On the other hand, if deforestation is stopped and replaced with a rational forest management, a reuse of degraded lands for agro-forestry and biomass production for energy and industrial purposes, we can reduce the pressure on forests lands and the net carbon flux will be reversed. In this paper, we discuss the relations with biodiversity losses and carbon emissions in Brazilian Amazon region in the last thirty years and find suggest the principal`s strategies to reduce this environmental`s destruction.
