Revisiting Earth Day: Lessons from the Past

In this episode of Hangin’ at the Reef, Dr. Regina Ostergaard‑Klem—acting Associate Dean of the College of Natural and Computational Sciences and instructor in both the undergraduate Environmental Science/Environmental Studies program and the Master’s in Sustainability graduate program at HPU—examines the evolution and enduring significance of Earth Day, from its 1970 origins to today’s global observance. She explores Hawai‘i’s grassroots sustainability efforts, introduces the Genuine Progress Indicator (GPI) as a more holistic measure than GDP, and underscores the power of transdisciplinary collaboration to address complex environmental challenges.
