Hunger is a seemingly simple word, but when considered in a global perspective, it takes the form of one of the most dreadful problems ever to confront humankind. This is a crisis created not by virulent pathogens, atmospheric changes or deadly nuclear warheads, but an inability of the human population to feed itself! World hunger is considered the worst threat in modern times, an estimation borne out by the fact that, at present, hunger-related issues claim more lives than malaria, HIV-AIDS and tuberculosis put together.
