• Coral reefs cover <1% of the world’s surface and hold 25% of all marine fish species.
  • We benefit from reefs through food security, coastal protection and cultural value, all for free.
  • Corals are a pharmaceutical dream with >50% of all new cancer drug research focused on marine life.
  • Recreational value of reefs is estimated to be US$9.6 billion, employing thousands of people.


  • Currently 75% of the world’s reefs are threatened.
  • Predictions for 2050 state that almost all reefs will be classified as threatened, with 75% at CRITICAL levels.
  • Without actions taken to minimize local stressors, the percent of threatened coral reefs worldwide will rise to 90% by 2030 and close to 100% by 2050 (Reefs at Risk).

Coral reefs are under significant and immediate threats. We work to alleviate some of those local threats leaving reef ecosystems stronger and healthier for a more hopeful future.


Coral has shown an incredible ability to withstand major climate events and sea level changes – there is hope for their survival if we take action now.

Why work with the diving industry?

  • Dive and snorkel tourism are not the main drivers of coral reef degradation, but these industries can lighten the load that reefs have to carry.
  • Dive and snorkel operators and their teams are in a unique position. With a natural understanding of reefs and a strong desire to protect them, they can be ocean ambassadors and role models for their clients and communities.

Through Green Fins, the member dive shops learn about global threats and status of coral reefs and collaboratively come up with solutions for lasting behavior change. From installing mooring buoys to reduce anchor damage, to ensuring proper waste management systems and minimising direct damage to coral from divers and snorkelers, Green Fins members give their dive sites the best chance they can to survive.

Research shows that businesses who have adopted Green Fins show measurable improvements in their environmental practices and a reduction in damaging contacts made by their divers
