Something feels different these days in a classroom at SD Negeri Sarang Tiung, an elementary school in Kotabaru, South Kalimantan. Teachers there once had to repeat the same reminders over and over, and lately those constant warnings have all but stopped. The shift traces back to Ocean LiteraSEA, a program that brings lessons about the sea to children growing up along the coast. Its premise is that small stories from coastal kids can shape how Indonesia looks after its waters in the years ahead.
