As stated by TNAFA
"Permaculture (permanent "agri" culture), is a holistic approach based on traditional practices for improving air quality, water quality, health, and ecosystems management. Permaculture is the harmonious integration of landscape and people, providing food, energy, shelter, and other needs in a sustainable way for all species. Permaculture is working with nature rather than against it; of protracted and thoughtful observation rather than thoughtless action; of looking at systems to evolve beneficially, on their own way, towards a state of maximum natural productivity and abundance."
CINTDIS is another seed-food-life-security organization on the other side of the globe that believes "all humans have the right and capability to understand the complexities of nature and society" and that "increasing specialization of disciplines has created a privileged class of people . . . who know details of tiny corners of the knowledge universe, but are ignorant of the social relevance and implications of their specialty"
