Ralph: In Service of the Sea

Episode Summary

IN SERVICE OF THE SEA · On this episode, longtime Mālama Maunalua volunteer and science educator Ralph Dykes joins from Maunalua, Oʻahu where he has spent over 15 years helping restore the native marine ecosystem. A consistent presence who kayaks every day, Ralph reflects on what it means to care for a place over time and why that kind of steady, local effort matters.
