Mexico is in the grip of the worst tortilla crisis in its modern history. Dramatically rising international corn prices, spurred by demand for the grain-based fuel ethanol, have led to expensive tortillas. That, in turn, has led to lower sales for vendors such as Rosales and angry protests by consumers.
Sometimes I'm not sure whether or not we, as members of society, think of the effects that our demands for cheaper fuel cause for others. This is one such instance. Is corn-based ethanol a "fix" for us that is going to cause problems for others? If so, then perhaps we need to rethink our stance on it, and move to a crop which will not have a negative impact, such as switchgrass.
