Dr. Samuel Alexander

“Anyone who has attempted to actually live simply, of course, will know very well that doing so is not very ‘simple’ at all, in the sense of being easy.  This is especially so in the consumerist cultures that have arisen today, which are dominated not only by materialistic values but also by growth-orientated structures that often lock people into high consumption lifestyles.  To be sure, it is hard to swim against the current of consumerism.  What this suggests is that the significance of simple living is not just about personal lifestyle choice, but has wider and deeper implications on how we think about the structures of our societies. As we will see, this raises political and macroeconomic issues, as well as ethical, cultural, ecological and even spiritual issues. It seems, then somewhat paradoxically, that simple living is actually an extremely complex notion that exhibits a multitude of dimensions and defies simplistic definition.” - Dr. Samuel Alexander

Peter 1.jpg

Peter Bane is the author of The Permaculture Handbook: Garden Farming for Town and Country, and a frequent contributor to Permaculture Design magazine (formerly Permaculture Activist). In 1994, he helped to found Earthaven Ecovillage in North Carolina where he built an off-grid home of natural materials. A solar energy pioneer, home remodeler, and microfarmer, Peter has provided consulting advice and design to landowners, municipalities, and universities for over 25 years. After moving to Bloomington, Indiana in 2006, he and his partner rebuilt an older home to achieve energy use reductions of 60% measured against the per capita U.S. residential average, based chiefly on the deployment of conventional building materials, passive solar design, grid-intertied photovoltaics, and changes in household practice that include rainwater collection, wastewater re-use, sustained yield harvest of wood fuel, sheet mulching with organic wastes, edible landscaping, and home food production and storage. He went on to advise the city of Bloomington on prospects for an Energy Descent future through his service on its 2008-09 Peak Oil Task Force. His teaching career has taken him from Canada to Patagonia, and among its highlights are launching permaculture education in the Caribbean island nation of Trinidad and Tobago and helping to inaugurate permaculture design at the Ecovillage Training Center in Tennessee, at Indiana University, and at Paul Smiths College, New York. In 2005 his work in Media, Education, Trusteeship, and Community Development was recognized with the Diploma of Permaculture Design by the Permaculture Academy of Britain. He currently serves on the board of the Permaculture Institute of North America, and is at work on a book about biological approaches to climate cooling.

Bob Brecha

"Many have you seen the Mauna Loa Observatory graphs co2 rising in and bumping up and down in wiggles during the course of the year. I would say that these iconic images are demonstrating not only the impact that we're having on the atmosphere - that is, we have increased by over 40 percent the co2 in the atmosphere - but it also shows a kind-of breathing. If you look carefully those graphs, it's not just a monotonic increase. It's an up and down every season. This is the breathing of the earth. Somehow this gives a sense of a living system, a living planet." - Bob Brecha

Dr. Robert Brecha was born and raised in Ohio. He is now a Professor of Physics at the University of Dayton. He teaches in the Renewable and Clean Energy Graduate Program and coordinates the Sustainability, Energy and the Environment (SEE) Minor and other SEE initiatives.  Since 2006 he has been working periodically as a visiting scientist at the Potsdam Institute for Climate Impact Research in Germany.

Jim Merkel

Jim Merkel is the author of Radical Simplicity: Small Footprints on a Finite Earth. Jim founded the Alternative Transportation Task Force in San Luis Obispo, California, and held an elected Sierra Club position while honing urban simple living skills. He lobbied in Washington for wilderness, peace, and Native American rights. In 1994 he received a fellowship to research sustainability in Kerala, India, and walked in the Himalayas. The following year he founded the Global Living Project (GLP) and initiated the GLP Summer Institute where teams of researchers attempted to live on an equitable portion of the biosphere.

Community Solutions is partnering with Jim Merkel on his new film, Saving Walden's World. The film will gingerly explore two of humanities sacred cows “be fruitful and multiply” and “he or she who dies with the most toys wins.” Together they lead the stampede to wreck the planet and underlie most environmental and social woes.  The viewers will be treated to an insider’s glimpse of societies that exhibit sustainable practices, that is, have small families, small ecological footprints and healthy, educated people.
