I am sure some people whom I have spoken to about Permaculture are wondering how it can possibly last without chemical intervention. To these new agers with their chemical inputs like you read about in Ag Weekly I have the following 2000 year old food forest to share with you. This forest is still in use & production and being worked by 800 families.
The same technology that created this food forest 2000 years ago has been replicated all over the world from places here along the Pacific Northwest, or Tasmania, to jungles in Vietnam, Australia & Hawaii. From the Finger Lake region of the Northeastern United States to all over Europe, Russia, and Africa. There is no continent and climate that this hasn't effected us already for the better.
