The story of the Eden Project is the story of a worked-out mine that was transformed into something incredible. And it’s not the only one. When mines and quarries close, they shouldn’t become scars on the landscape or sources of pollution or leave their working communities on the brink of collapse. With imagination and determination, they can offer something radically different — hope. 102 Things to Do with a Hole in the Ground takes the reader on a tour of some of the world’s best and most unusual ways of dealing with former mining and associated industrial sites, including carbon-capturing mine wastes, a brewery, a cake mine, an opera house, racecourses and golf courses, ski slopes, vineyards, reconstructed ecosystems, a digital archive inside the Arctic Circle, and the Eden Project itself. It contains 15 Australian cases.
