What should we do?

I was moved and inspired by this post by a blogger whom I greatly respect and admire. This is the boldest reaction I have seen from anyone in the food community in response to the global food crisis. The worlds' poorest nations are running out of rice to eat, with no relief in sight, and the New York Times is running articles about luxury airport food. The shortage is so widespread that even the United States is affected--consumers have seen price increases on basic food items, and I heard on NPR that Costco is limiting its sale of rice. I wonder how far it will have to go before the US actually does something to help alleviate the hunger of other countries. I write this with all four burners working, simmering and sauteing, the smells of simmering beans and vegetable stock filling my kitchen, fully conscious of how lucky I am to be so choosy about what I eat. We live in a country where people define themselves by what they don't eat, rather than by what they do. And I ask, what should the "foodie" community do? How do we respond? Do we donate money, or stop buying rice? What do some of the most privileged eaters of the most privileged nation do during a global food crisis?
