The question should really be "How are many national economies keeping innumerable people hungry, even though there's plenty of food to go around several times over?"
In most places in the world it's easy and cheap enough to produce food and distribute it. Actually, it's so easy and cheap that many world states artificially subsidize agriculture/livestock farming/etc. to prevent them from collapsing due to low prices.
