Coffee is a major export commodity: it was the top agricultural export for twelve countries in 2004,[8] the world's seventh-largest legal agricultural export by value in 2005,[9] and "the second most valuable commodity exported by developing countries," from 1970 to circa 2000.[10][11]This last fact is frequently misstated; seecommodity market, below. Further, green (unroasted) coffee is one of the most traded agricultural commodities in the world.[12]Some controversy is associated with coffee cultivation and its impact on the environment. Consequently, organic coffee is an expanding market.
