For Beyond 50's "Sustainable & Eco-Friendly Practices" talks, listen to an interview with Leonard Barrett of Barrett Ecological and Trackers NW about permaculture that was developed in Australia. The method is both ecologically sound and economically viable. It is based on the idea of creating human habitats and gardens that exist in harmony with the existing ecology, creating environments that are truly greater than the sum of their parts. Healthy, beautiful and productive environments naturally follow good design. Visit www.Beyond50Radio.com and sign up for our free e-newsletter.
