"Supply and Demand in the Irish Potato Famine"

During the Irish Potato famine, at least a million starved to death and at least as many emigrated --as we all know -- while the English landlords continued to export food from Ireland to Britain and the Continent.

I would like to see the supply demand curve for this.

It would seem (from the viewpoint of the economist) that demand for food fell during the famine. Since peasants had no money, they could exert no demand (demonstrations, rioting, theft etc. are, of course, not considered modes of expressing demand).

It is an interesting point of view: I can starve to death, needing and desiring food, but without "demanding" it. I can only "demand" it if I present whatever amount of money is required to buy it.

In the Energy Descent to come, presumably things will be similar. Demand (as defined above) will fall, but it won't be because desire or need has lessened in any way.
