Where I come from – Hawai’i – the reef isn’t just something you look at. It’s part of us. It feeds our families, protects our shores, and lives at the centre of our culture. In our stories, coral is one of our oldest ancestors. It’s a reminder that everything in the ocean, and all of us, are connected.
Right now, that integral connection is under threat.
Our coral reefs are under severe stress. The planet has just experienced the most widespread coral bleaching event ever recorded, lasting 33 months into 2025. Scientists warn that at 1.5C of global warming, up to 90% of coral reefs could be lost. Ninety per cent. And 1.5C is not lingering in the distance – it’s extremely close.
Even if the world somehow hits its climate targets, reefs are still getting pummeled by plastic pollution, coastal development, agricultural runoff and overfishing. They’re so fragile. And when reefs weaken, coastlines get hit harder by storms and rising seas. Homes and jobs become exposed. Cultures and sacred places are put at risk. And the incredible range of underwater life found only in reefs – once it’s gone, it’s gone for good.
But I refuse to let coral reefs be a lost cause.
