“…In fact, the contribution of manufactured goods in Brazil's exports increased from less than 30 percent in 1974 to more than 50 percent in 1981, oscillating between 50 and 60 percent ever since (Cardoso, 2009). Even though the relative environmental impacts of primary and processing activities are difficult to evaluate and compare, in general, the environmental degradation arising from producing primary products is more severe than that caused by further processing (Hecht, 1997;but see OECD, 1996). More precisely, the production of primary commodities affects the long-term sustainability of the resource base, through deforestation, soil erosion, fertilizer/pesticide residue, habitat destruction, biodiversity loss, etc., whereas processing activities result in water, air and land pollution (OECD, 1996).…”
