The name "ecovillages" makes them sound new and revolutionary, part of a new movement toward sustainability and community. But in reality, this is the way humans have lived for thousands of years before we took a sharp turn toward unsustainable living.  Ecovillages are glimpses to the past, to how humankind used to resonate with the natural environment.  They are spreading and popping up everywhere where people are found. Karen Litfin embarked on a journey to many of the world's ecovillages - intentional communities at the cutting-edge of sustainable living. From rural to urban, high tech to low tech, spiritual to secular, she discovered an under-the-radar global movement making positive and radical changes from the ground up. She documented her discoveries in her book, Ecovillages: Lessons for Sustainable Community. Hear her adventures first hand on a Tuesday night in downtown Olympia.
