Much of the world is turning hotter and dryer these days, and it's opening new doors for a water-saving cereal that's been called "the camel of crops": sorghum. In an odd twist, this old-fashioned crop even seems to be catching on among consumers who are looking for "ancient grains" that have been relatively untouched by modern agriculture.
Sorghum isn't nearly as famous as the big three of global agriculture: corn, rice and wheat. But maybe it should be. It's a plant for tough times, and tough places.
