The greatest challenge for any intentional community is to exceed the lifespan of a single generation, that of the founders. Young people inevitably become restless and leave; older people fall out with each other, go through divorces and separations, and such events can disrupt a small community beyond repair. The solution is to form not just one community but a network of them, so that people, especially young people, can move between them in search of friends, mates and new experiences. Join Northern Sustainability Featured Speaker Dmitry Orlov for a seminar that will explore a variety of organizing principles that can be brought to bear in creating viable networks of communities that, perhaps not separately but together, have the vitality to go on for many generations.
