This is one of the best examples of systems dynamics that I have seen in a good long while. We have to stop looking for fixes for one problem without analyzing the consequences that fix might have on other aspects of life.

Corn Can’t Solve Our Problem
The world has come full circle. A century ago our first transportation biofuels — the hay and oats fed to our horses — were replaced by gasoline. Today, ethanol from corn and biodiesel from soybeans have begun edging out gasoline and diesel.
This has been hailed as an overwhelmingly positive development that will help us reduce the threat of climate change and ease our dependence on foreign oil. In political circles, ethanol is the flavor of the day, and presidential candidates have been cycling through Iowa extolling its benefits. Lost in the ethanol-induced euphoria, however, is the fact that three of our most fundamental needs — food, energy, and a livable and sustainable environment — are now in direct conflict. Moreover, our recent analyses of the full costs and benefits of various biofuels, performed at the University of Minnesota, present a markedly different and more nuanced picture than has been heard on the campaign trail.
Finding and implementing solutions to the food, fuel and environment conflict is one of the greatest challenges facing humanity. But solutions will be neither adopted nor sought until we understand the interlinked problems we face. (see full article for the rest of the article)
