50 Reefs


In some places, reefs have been entirely destroyed, while in others they are a shadow of what they once were. Nearly 90% percent of the world’s reefs will be gone by 2050. The 50 Reefs initiative aims to identify the coral reefs that are least vulnerable to climate change and that are also capable of regenerating in the future.

Coral Reefs Are The Most Diverse Ecosystems On The Planet And They Are On The Brink Of Extinction

Coral reefs are disappearing at increasing rates (1-2% per year) and are on track to disappear completely in 30-40 years. We have already lost 50% of corals in the last 30 years.  Home to one in every four fish in the ocean, the extinction of coral reefs will have major economic and environmental impacts.

Climate change and local threats like pollution and poor fishing practices are taking a toll on the ocean floors. The threat to coral reefs is especially critical for the half billion people who depend on reefs for their livelihoods, particularly in some of the world’s poorest developing countries. We will lose coral reefs entirely if we don’t act now to best protect what can be saved.

The 50 Reefs Initiative is the First Global Plan to Protect the World’s Coral Reefs

The initiative brings together leading ocean, climate and marine scientists as well as conservation practitioners from around the world to develop a list of the 50 most critical coral reefs to protect.

The final list and corresponding initiatives, to be announced later this year, will raise awareness of the increasing severity of climate change impacts on the ocean and catalyze the global action and investment required to protect these important reef systems for the future.

It is supported by a unique philanthropic coalition of innovators in business, technology and government, led by Bloomberg Philanthropies with The Tiffany & Co. Foundation and The Paul G. Allen Family Foundation.
