brent: we are joined by steve tarbell a in washington. steve, it's good to have you on the show.hat are the different reasons we are seeing the situation at the moment? reporter: i was pleased to hear your reporter described this is a man-made con act. that is what we are facing here. the world program response to earthquakes, flooding, typhoon. this is a case, this severe crisis could have been averted. the fighting over the past three years has made it impossible to meet the countries food needs. especially resources, energy, attention has been devoted to agricultural production to the conflict. you can't farm if you are fighting. the fighting has led to a shortage of food commodities. and where there is food, there just isn't enough money to buy it. the economy has deteriorated to the point where i think 82 south sudanese pounds are needed to buy one u.s. dollar. it is down from a year ago. it is pretty dramatic. brent: you have done a good job of showing us the hurdles people are facing trying to feed themselves. what about people trying to help like you? what is the hurdle?
