Four decades ago, a group of South Americans joined together to create an ecological utopia. The village, called Gaviotas, was based on the idea that they could use limited resources to create a sustainable community. In 1998, journalist Alan Weisman wrote a book about the Colombian experiment. It’s called “Gaviotas: A Village to Reinvent the World” and it’s just been updated for a 10th anniversary edition. Weisman talks with host Steve Curwood about his recent visit to Gaviotas and how the community is faring.
