why die of hunger when food is aplenty

poverty is many things. but lack of food comes first.
 but it is not becoz there is shortage of food in the world.
the problem is distribution.
cant we think of a system where food items  move  freely
across borders ? no restrictions. no levies. no import export
formalities. no checking. no stopping. no delay. just free flow.
only for eatables.
of course free of cost too . and free transportaion if we have the will.
just for food. to help every one eat. to ensure no one dies of hunger.
