That is a jump from about 1.5 million acres a year earlier and just over 1.2 million acres the year before that, according to estimates by Brazil’s National Institute for Space Research."

"Now, a new study by an environmental advocacy group points to fresh indications of large-scale forest-clearing by Bolivian and Brazilian farmers who trade soybeans with Cargill.
That organization, Washington-based Mighty Earth, used satellite imaging and supply-chain mapping information from the Stockholm Environment Institute, an environmental think tank, to identify deforestation in Brazil where two American-based food giants, Cargill and Bunge, are the only known agricultural traders. The supply-chain mapping by the environmental institute uses customs, shipment and storage data, as well as production data from Brazilian municipalities to trace agricultural exports back to producers."
