Document Summary
Sustainability: the ability of a system to continue to do what it is designed to do. Made to provide fresh air and clean water. Made to allow satisfactory quality of life. 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. If our food system was sustainable, we would have food security. Unsustainability: the practice or process or system can not go on indefinitely because it is destroying the bery conditions on which it depends. Within, there are internal contradictions that will lead to its breakdown sooner or later. For the past 5-6 years, food systems 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, no crop rotation, and no variation in commodity from year to year.
