WWF works to sustain the natural world for the benefit of people and wildlife, collaborating with partners from local to global levels in nearly 100 countries.
Reef corals' intricate structures are the hubs of busy, biodiversity-rich ecosystems. But around the world, rising ocean temperatures and CO2 levels are driving away or killing the algae that keep corals healthy and colorful—and sometimes even turning entire reefs into bleached, ghostly graveyards. In Belize, WWF and local nonprofit Fragments of Hope are using coral nurseries to cultivate climate-resilient varieties—then planting those new varieties on struggling reefs.
