More and more we are starting to see elaboration of the idea that we --the people, can only be as healthy as our planet. That puts the responsibility you know where.

“Permaculture is an ecological design system for sustainability in all aspects of human endeavor. It teaches us how to design natural homes and abundant food production systems, regenerate degraded landscapes and ecosystems, develop ethical economies and communities, and much more. As an ecological design system, permaculture focuses on the interconnections between things more than individual parts.” Permaculture Institute

You start, of course, in your own back yard, where ever that back yard may be.

The key to understanding permaculture is being able to see wholes comprised of interconnections---not just the sum of its parts.

Another way to look at permaculture is to work with nature and not against it. Observe how natural systems work and replicate it including items useful to you. Thanks for posting hazelnut.

One of the founders, David Holmgren, presents an operational definition of permaculture in the form of a flower, to illustrate the basic procedure for thinking in a permaculture mode.

A new definition of the permaculture flower has been proposed at PRI --Permaculture Research Institute of Australia. To my mind, this Americanized model leaves out some essential themes that are important in the original model. The fact that permaculture is ethics driven, for example, and the idea that permaculture systems are not designed, just to meet human needs in a particular situation--they are at the same time meant to heal the earth, i.e. the designs are meant to relate to natural ecosystems and global environmental concerns..
