Why study agriculture instead of finance- Jim Rogers

"Until prices reach a point where growing food is profitable, the world's farmers, who are currently aging and dying are not going to be replaced. Prices must rise, and they will. In recent years, the world has been consuming more food than it has produced. Those inventories that were so high in the 1980s are now historically low, somewhere near 14 percent of consumption (vs  ~35 percent of consumption in the 1980s). The world is facing dramatic shortages." Jim Rogers
