Food Sustainability in the Context of Human Behavior

The long-term goal of food sustainability is to produce enough food to maintain the human population. The intrinsic factors to guarantee a sustainable food system are a fertile land, water, fertilizers, a stable climate, and energy. However, as the world population grows, the volume of food needed in the future will not depend just on these intrinsic factors, but on human choices. This paper analyzes some of the human actions that may affect the sustainable future of the food supply chain, including diet, obesity, food miles, food waste, and genetically modified organisms.
