Brazilian real
Forest removal to make way for cattle ranching was the leading cause of deforestation in the Brazilian Amazon from the mid-1960s on. In addition to Vargas's earlier goal of commercial development, the devaluation of the Brazilian real against the dollar had the result of doubling the price of beef in reals; this gave ranchers a widespread incentive to increase the size of their cattle ranches and areas under pasture for mass beef production, resulting in large areas of forest removal.
