Researchers (Heimann, 2004) admit that hunger is hidden Canada, and consequently much closer to the doorsteps than researchers are apt to think. Coming from the rural areas to a crowded, neglected urban ghetto, they suddenly encountered a host of living problems that they were not equipped to handle, and these have further diluted their ability to assemble an adequate diet (Vernon, 2007). The Human Resources Development Canada estimates that one-third to one-half of the world's people suffer from nutritional deprivation. In the low-income countries alone, one-half to two-thirds fall into that category by various estimates. Norman E. Borlaug, who has played a key role in expanding world food production, estimates that half of the world's population is undernourished and two-thirds is malnourished (cited Russell, 2006). It is fair to conclude that in poor countries as a whole, the poor comprise a hungry majority. Communities call nutritionally deprived people "hungry," even though the term is far from precise and may or may not include the feeling of hunger. Some are under nourished--incapable of getting enough calories each day to provide their bodies with fuel for minimal demands. These calorie-deficient persons number about a half billion, and the total would rise substantially if it were figured on the basis of people's potential (rather than minimal) functioning capacity.
