Food production in the United States is currently dominated by two methods: organic farming and traditional farming that incorporates the benefits of engineered seeds. If early successes are any indication of the future, then it may soon be time to make room for a third: vertical farming. There are numerous benefits to vertical farms, which are springing up from Singapore to Pennsylvania, ranging from the elimination of pests to significant reductions in the amount of water used to irrigate crops. However, the disruptive shift in the way the world produces food will also reshape the battle between organic champions such as Whole Foods Market (NASDAQ: WFM ) and engineered seed producers such as Monsanto Company (NYSE: MON ) .
