Maybe we give them to many rights and freedoms which gives them the chance to be reckless without consequence. Also what countries are going to be the top dog when the U.S. and other core countries become morbidly obese. Let me give you a hint is the people who eat natural things that aren't completely filled with fat and other self-harming ingredients.
You think that the United States is peaceful we have the top incarceration rate. Also i have been to a third world country and they live in a tight knit society and are more than capable of producing natural food. Africa is no different they have the means and the labor to support themselves.
