Combat hunger all over the world

Total amount of food produced on our planet is far more than enough to feed current world’s population. So, why we haven’t organized yet a net that could deploy produced food to anybody who urgently needs it. I cannot believe that it’s impossible to elaborate technology which develop with a kind of fermentation food wastes into maybe not so attractive but healthy and not decayed food. Such food could be distributed to starving people for free like water in drinking fountains.
