I came to wanting to do that from volunteering at my daughter's school. They had a pretty sizable contingent getting free lunches and breakfasts (the absolute numbers are public. The exact identities are not), and I remembered hearing, over and over, that one in four kids lives 'food insecure.' I'd watch a class in the school library and wonder which ones went hungry when school was cancelled. One in four out of thirty kids you're looking at right in front of you is a much more concrete thing, especially knowing their names and what they like to read.
