while everyone is blaming the US for having inadequate food drops, low donation percentages, etc., people gotta realize that these are partially to blame for the growing population problem in many third world countries. Malthusian theory states that population grows geometrically ( 1, 2, 4, 8,....) while food sources grow arithmetically ( 1,2,3,4,....). Now in an area without many resources, a population will eventually settle upon a birth / death rate that can support those living. However wen we fly our little planes in there and suddenly increase the food sources, the birth rate skyrockets, while the death rate doesn't have time to react accordingly. So in essence the second we stop dropping that level of food, overpopulation leads to starvation in an effort for the death rate to equal birth rate, once again leveling off the population.
if you really want to do some research on the matter look into thomas malthus, and for an opposing view on the matter, william godwin.
