In the farmland of eastern England, a search-and-rescue mission is underway. A team is working to excavate land haunted by ghosts… but these are not ordinary ghosts…these are ghost ponds. Norfolk used to have a record number of ponds, but modern-day farming is burying England’s wetlands at an exponential rate. With a looming biodiversity crisis, a grassroots movement is reviving farmland ponds as an unexpected last hope to reverse biodiversity loss and protect freshwater wildlife. Will it be the smallest changes that can make the biggest difference?
