I think the obvious thing is that if people are hungry, they get angry and they riot in the streets. We did see that in 2009 and 2010.
Even beyond that, we often are dealing with what we call “hidden hunger”. It's a situation, usually with children, when they are getting sufficient calories and their bellies are full, but they're not getting full nutrition. Those are the kids who really struggle in school. They are not going to get a full education and they're not going to be able to work to their full capacity as adults.
Imagine 60% of a population in a country who are suffering this hidden hunger and not able to achieve their potential. That really holds a country back from what they can achieve, whether in business or in international relations or whatever it is. That's one example.
Another example I'll give is the Democratic Republic of Congo. I saw a report today that said there are about seven million people displaced in that country because of conflict, and a lot of that is lack of food, lack of land and conflict over resources. People are being killed and people are having to leave their land, and that is spilling over across borders as well.
Those are a couple of examples of what happens when people just can't access enough food.
