This paper is not intended to be scholarly treatise. It is intended to stimulate thinking about the impossibility of taking care of the whole population in the schools, churches or community centers. Let's use Fairfax County, Virginia, as an example. 629 Average Total Population per School 3901 Nutritional charts show a 10 year old child needs about 2000 calories per day. I use this number because it works for the average adult too.
Beans are an inexpensive and readily available source of nourishment.
They provide enough food value to keep a person alive for a while. Because canned beans don't need to be cooked to be edible, they can be served even if no cooking facilities are functional. Beans are not a complete source of nutrition, they merely illustrate the impossibility of storing enough food and water in schools to feed the whole population. The average school in Fairfax County serves a population of 3901 people, including adults and children. Assume all 3901 people need shelter at the school because everyone believed the Y2K optimists and made no preparations.
