Document Summary
Food security: physical and economic access by all people in a society at all times to enough culturally and nutritionally appropriate food for a healthy and active lifestyle. Unsustainable: the practice, process or system cannot go on indefinitely because it is destroying the very conditions on which it depends. Within the practice, process or system there are internal contradictions that will lead to its breakdown sooner or later. Industrial farming reduces biodiversity; it depletes the inputs on which food production depends. Reduction in biodiversity triggers a vicious cycle of increased use of synthetic inputs and reduced biodiversity. For the past 5-6 decades, food systems of developed countries have been sustained by: Clearing indigenous plants and trees from larger and larger swaths of land. Farming a single species of plant (or animal) with highly mechanized processes , and no variation in commodity. Using natural gas-based pesticides and genetic modification to manage biological pests.
