Most of us don't think too much about world hunger. When we are hungry, we can always find something to eat ---- usually something good. But in many parts of the world ---- even in some rich countries ---- adults and children go to bed hungry every night. Accordin to the World Hunger Programme in Newport, Rhode Island, 780 million people in the world don't get enought to eat. One out of six babies in the world is born underweight and even worse, one out of every three children is underweight at age five. There are two main causes of hunger --- food "shrtage" and food "poverty." A food shortage happens when there isn't enough food in an area to feed all the people who live there. This has happened recently in some African countries when there wasn't enough rain for people to grow the food they need. Sometimes a food shortage affects just one part of a country, but at other times the entire country is affected. Food poverty is hunger which results when people don't hav enough money to buy food. There is plenty of food in the stores, but some people can't afford to buy enough food, so they go hungry.
