text: According to the book, "Eco-Sanity," "If deforestation in Brazil accounted for half of all rainforest deforestation in the world, as is generally assumed, then the new estimate means the global rate of rainforest deforestation was just 3 million hectares per year (app. 7.5 million acres) during much of the 1980's. As a percentage of existing rainforests, the annual loss was less than a tenth of one percent."(Eco-Sanity, p.84)
