Check out these 3 videos. A 30 year old food forest from Australia, a 300 year old forest in Vietnam and a 2,000 year old food forest in Morocco. Why not take some design tips from Mother Nature?
Let's be honest. The Western approach to agriculture is egocentric and superfluous. This gardening system requires plants to be almost completely dependant on human and mechanical activity. It's extremely labour intensive with a dependency on chemical fertilizers and irrigation. Basically it's drug pushing. And, the plants are annuals so this process needs to be repeated from beginning to end EVERY year.

In many of the other countries around the world, food crops become naturalized and develop into there own ecosystem, requiring very little human aid to keep this structure functioning. Medicinal plants grow throughout this system and ultimately these "food forest" floors become something similar to a first aid kit. These plots of valuable land are passed on from generation to generation. Each generation is taught how to handle the plants on the property and learn their purpose. Chickens and livestock also become part of this matrix and run freely fertilizing the soil.
