Deforestation in the Amazon River Basin has been going on for decades as huge amounts of land have become necessary to support the area's growing agricultural industry. Road building, agriculture, ranching and logging have had devastating effects on tropical forests and change has been rapid as deforestation of the area only began around 1970 (Fearnside, Pfaff). Governments of Amazonian countries have designed their current initiatives to increase infrastructure and businesses, but these initiatives are largely responsible for deforestation activity (Laurance). The decline of this region's forests has become a serious problem as the effects it has on the climate and ecosystem of the Amazon River basin and the rest of the world are great. The high rate of deforestation in this area, averaging 25,000 to 50,000 square kilometers per year since 1970, suggests numbers projecting a complete absence of tropical Amazon rainforest within the next 50 to 100 years if increased methods of deforestation are not adopted. prevention (Shukla). These numerical projections represent a threatening future for deforestation dynamics, carbon flows, forest fragmentation, affected ecosystems, social issues, and climates both in the region and globally. Recent changes in the Amazon River basin are a direct result of deforestation. Climate change in the area highlights the negative impact that the loss of tropical forests has had in this area. Since the presence or absence of vegetation directly influences regional climate, as demonstrated through controlled numerical experiments with complex models of the atmosphere, studies have shown that climate change in this area is largely due to deforestation.
