Global Food Crisis?

There have been occasional articles in the past on a predicted global food crisis. In the last decade these articles seem to be occurring with more and more frequency on the topic of what some are starting to call the impending global food crisis. These articles tend to hint at the upward trend in food prices over the last decade. The opinions on what is causing this increase is varied depending on what you read or see on the news. Here is an article that blends economics, the current political situation in Egypt and the looming global food crisis. The intent I think is to explain the predicted global food crisis in a way that everyone can understand.
