We may think we live in a digital age, but only half the world is  currently online. Across the globe, small radio stations bind remote  communities, play a dazzling array of music, educate, entertain and  empower people to make change. Cameroon’s Radio Taboo, in a remote  rainforest village 100 miles off the grid, relies on solar power; its  journalists and engineers are all local men and women. Radio Civic  Sfantu Gheorghe in the Danube Delta preserves the history of the  community. Tamil Nadu’s Kadal Osai (“the sound of the ocean”) broadcasts  to local fishermen about weather, fishing techniques—and climate  change. In Bolivia, Radio Pio Doce is one of the last remaining stations  founded in the 1950s to organise mostly indigenous tin miners against  successive dictatorships. And KTNN, the Voice of the Navajo Nation,  helps lift its listeners’ spirits in a time of loss and grief.
