High population means high demand for food and in turn high demand on the soil. With 30% of the world’s population presently undernourished, scientists are hard pressed to find new ways of increasing food production. Even more pressing are improved methods of food storage to sustain the existing population from year to year. Food storage, therefore, has tremendous effects on population growth by:
1. providing food reserves for emergencies like famine, war and other natural disasters like floods, earthquakes, etc;
2. making food to be available throughout the year. In developing countries there is surplus food at harvest time and starvation after the planting season. The major effect of food storage is to eliminate such fluctuations.
