On this episode of Eco Echo, host Nil Kıran welcomes back guest Arda Kalın to explore the world of green graffiti—where nature and street art collide. From moss murals that grow on city walls to seed-bomb installations that turn vacant lots into gardens, we discuss how eco-art is reshaping urban spaces. Arda explains the science behind living graffiti, the activism driving seed bombs, and why these creative interventions matter for sustainability. Together, we look at how art can inspire community action, support biodiversity, and reimagine the gray corners of our cities as spaces for life and renewal.
