Permaculture Principles
Permaculture is a set of principles for the design of sustainable humun habitats which have a minimal impact on other species. We learn from wild ecosystems, while also utilizing methods from traditional cultures as well as cutting-edge appropriate technology. The resulting abundance is then shared with others. See some photos of a few permaculture samples. For some practical urban applications, see Heiko Koester's Ten Easy Permaculture Tricks for Your Garden.
