"Permaculture" - A word coined by Bill Mollison.
Permaculture (permanent agriculture) is the conscious design and maintenance of agriculturally productive ecosystems which have the diversity, stability, and resilience of natural ecosystems. It is the harmonious integration of landscape and people providing their food, energy, shelter and other material and non-material needs in a sustainable way.
The philosophy of permaculture lends itself to working with, rather than against, nature.
The prime directive of permaculture: The only ethical decision is to take responsibility for our own existence and that of our children.
