Exhibit Panels
When people talk about the future of Appalachia, they typically mean economic futures: What will happen to coal jobs? How will Appalachia diversify its economy? What about poverty? Stereotypes about our region represent our people as disinterested in education, and hostile to innovation, technology, and sustainability. We see a different story. This part of the exhibit looks at ways that Appalachians are taking their strong sense of culture, their linguistic distinctiveness, and their relationship to the natural world to imagine new futures in diverse industries, sustainable practices, and stronger education systems.
