The document discusses the need for Appalachia to transition to a more sustainable economy and agriculture over the next 30 years as coal dependence declines. It proposes diversifying the economy by investing in alternative energies like solar and wind. Old mining sites could become parks or farms. A sustainable Appalachia would have a more localized food system with community supported agriculture and education about farming techniques. The transition may be difficult initially but create long-term stability through a more diversified economy and locally focused agriculture.
