"An urgent, eye-opening journey into the vibrant world of coral reefs—and why they’re disappearing before our eyes. Imagine a glowing underwater city, teeming with life, color, and perfect harmony. Now imagine it fading—silently, invisibly—beneath the waves. In this powerful TEDx-style talk, 9th-grade student and open water certified diver Reyansh Ambani takes us beneath the surface to reveal the breathtaking beauty and shocking fragility of coral reefs. Drawing on personal diving experiences, global research, and creative climate solutions, Reyansh delivers a passionate call to action that’s as poetic as it is practical."
