Using our current modern systems of industrial agriculture, the food production system is not sustainable. That means, by definition, that it cannot be sustained. Which is another way of saying that it is going to end.
Permaculture is in part an attempt to create a renewable system of food production that relies upon minimal amounts of energy. Industrial agriculture requires large amounts of fossil fuels, both to run the equipment, and to supply pesticides and fertilisers. Permaculture, on the other hand, focuses on maximizing the use of trees and perennial food crops — because they make a more efficient and long term use of energy than traditional seasonal crops. A farmer does not have to exert energy every year replanting them, and this frees up that energy to be used somewhere else.
Growing fruit trees is therefore an integral part of permaculture, and of any long-term plan to feed and support human populations. Fruit and nut trees and other perennial plants are used to plant a forest garden, or "food forest".
