The future of the coral reef is in (y)our hands.
While climate change is a well-known threat, direct human impacts also weaken reef health, leaving corals more vulnerable to rising ocean temperatures, which often deliver the final blow.
The good news? These local impacts can be addressed!
That’s why it is crucial for those visiting our awe-inspiring underwater world, divers, to understand what they are witnessing.
With the right knowledge and tools, they can become active Ocean Champions.
Collective global action is essential to address the issue, but individuals working and exploring on reefs have a unique opportunity to make an immediate, measurable impact.
