Over the past 4 decades, almost 20 percent of the Amazon rain forest in Brazil has been cut down. This area is equivalent to the size of Western Europe. Scientists are now warning that another 20 percent will be lost in the next 2 decades (Wallace, 2007). Selective logging for timber usually begins the process, followed by rapid deforestation, mainly for pasture and agricultural land. Some of the major implications associated with loss of forest include loss of watershed protection, decreased carbon sequestration, loss of ecotourism, lowered existence value, depletion of genetic resources, decreased biological wealth and cultural heritage (Thurston and Burness 2006; Nepstad and others 2006). Currently, the primary drivers of deforestation are the soy and beef industries, both of which are themselves driven by national and international markets (Nepstad and others 2006).
[...] Vegetation and deforestation in the Brazilian Amazon as of 2001, from World Resources Institute 2007. Some socioeconomic impacts will likely become more evident as the agroindustry continues to expand. Family-owned farms and indigenous communities will be displaced. Land ownership disputes over property claims and land thievery have become very common in Brazil. Land ‘sharks' even go so far as to age phony land titles in order to profit from land that is not theirs (Wallace 2007). Evaluation The Brazilian government's intervention in the situation occurring in the Amazon has focused on controlling fraudulent activity and zoning certain regions of land. [...]

[...] Drivers of deforestation in the Brazilian Amazon, from Nepstad and others 2006. Figure 3. Trends in annual Amazon deforestation, the Amazon cattle herd, Amazon soy production, total soy exports from Brazil to the Europe Union and China, and the value of the Brazilian Real (in U.S. dollars), from Nepstad and others 2006. The soya plant has now joined the cattle industry as the leading driver of deforestation as the Amazon has become the world's largest supplier of non- genetically modified soy (Nepstad 2006). [...]
[...] It is in part a result of reduced consumption of poultry due to the fear of avian flu. Reduced poultry consumption decreases the need for poultry ration, which contains soy, and therefore this lowers soy prices (Nepstad 2006). Looking into the future, and considering the factors outlined in Figure this decline is not expected to continue, and deforestation is expected to increase. Something needs to be done about it. As a result of the deforestation in the Amazon (Figure there will be many detrimental physical and biological impacts. [...]
