" UNICEF estimates that 22,000 children die each day due to poverty. Nearly one billion people are so illiterate that they cannot even sign their names. Half the children in the world live below the global poverty line. Roughly 1.6 billion people live without electricity. Even in a country like the United States, poverty is stark. Nearly 50 percent of all children in the United States will at some point be on food stamps. About 15 percent of American households had trouble finding food for the family at some point during the year. "
