For those of us that practice permaculture, the economic benefits that flow from employing the principles of it are obvious. Less maintenance through design, better fruit and veges and creative recycling etc. However, I have found a lot of people that don't know much about it think it is just a hippy thing that some do and have no idea of the benefits until they are told. And i've found if you approach it in a way that sells the economic benefits and the time saving measures up front, more people are interested. I may be wrong but permaculture is put across more as a self sufficiency idea which makes some people dismiss it straight off. maybe if we focus on the economic and time benefits (and let's face it many are time poor these days including me) we may educate a few more people to the benefits of permaculture to people and the environment. Are there any books that focus on this aspect?
