ABSTRACT
Hunger triggered the search for food within the cornucopia in the surrounding areas. Early humans ate a wide variety of plants and animals, following the abundance of each season. Ecosystems are living systems which begin at micro levels and radiate to the higher systems, creating stability at all levels. The ability of each smaller ecosystem to respond to the changing conditions maintains security and sustainability of that ecosystem. The resiliance of complex biological systems, or the capacity to recover quickly from a disturbance, is dependent on redundancy, plasticity, robustness, and stability. Knowledge of food and water systems is essential for human survival. The most basic function of food and water is survival of the human species. The food-water-energy nexus considers the multiple functions and interrelationships of inputs required by the ecosystem and humans, and this nexus is increasingly challenged in the Anthropocene.
