To paraphrase the late Sam Kinison regarding the Ethiopian "famine" in the 1980s: "You live in a DESERT! MOVE to where the F%$#ing FOOD is, you (censored), (censored)ing (censored)ers."
Brazil has had two years of record corn and soy bean crops. They have run out of storage space. The main impediment to selling it abroad is transportation problems. The surplus is due to good weather and government price supports above the world prices. The price supports are to keep food cheap to calm urban poor and to keep farmers on land and out of cities which are over crowded.
