The Reef We Stand to Lose: Coral, Bleaching and Hope in Hawaiʻi
Hawaiʻi's reefs are the foundation of its ocean life — and a front line in the fight against warming seas.

Every snorkel, dive and surf session in Hawaiʻi rests, quite literally, on coral. These living reefs shelter a quarter of all marine species, buffer the coast from storms and anchor the culture and economy of the islands — which is why the recent waves of coral bleaching have alarmed scientists and communities alike.
Why Reefs Are Struggling
When ocean temperatures spike, corals expel the algae that feed and color them, turning ghostly white and, if the heat persists, dying. Warming seas, pollution, and damaging sunscreens have all taken a toll, and Hawaiʻi has responded with reef-safe sunscreen laws and marine protected areas.
What Visitors Can Do
Individual choices genuinely add up: use mineral sunscreen, never touch or stand on coral, support marine reserves, and choose tour operators with strong conservation practices. The reef's future is not yet written, and travelers are part of the story either way.
Protecting the reef isn't someone else's job — it starts with the sunscreen you pack and where you put your fins.
How to Help
- Use only mineral, reef-safe sunscreen
- Never touch, kick or stand on coral
- Support marine protected areas and reserves
- Choose operators with real conservation practices
The water gives back what you bring to it — patience, respect, and a little nerve.
