permaculture: A design science that integrates the best of ancient wisdom, ecology, agriculture, urban design, energy efficiency and human activities, yielding a net result of abundance for all. I've seen permaculture sites that created oases in deserts, protected inhabitants and habitat from mammoth storms generated by global warming, or turned chemically intensive industries such as sewer processing into bio-intensive wetlands that attract humans and wildlife alike. It's how we design what we do that matters.
