The Look

This is a picture is in the context of rising food price, and I feel bad every time I look at it.

There are quite a lot of things I can think about by looking at this picture alone:

1. The rising food prices, and the ramifications
2. Why old people, specifically, this old lady, has such expression when paying for the food?
3. What are the challenges ahead for countries that have agricultural produces, and those that don't?
4. What are the nascent business opportunities, given food is more and more scarce and prices fluctuate much more violently?

All these can be independent essays by themselves.
