More important - where are the majority of these people?
In the countryside?
In cities?
In many cities like New York and London, you can go along to food banks and are given a selection of fresh or just-expiring food. Apart from some branches of Pick n Pay Family store, there are not many visible organisations
I have donated to the School Feeding Scheme and started to donate to Foodbank.org.za until I found that much was siphoned off for administration. Foodforward works better and has offices in Thornton
