from leaders may unintentionally normalize poor environmental practices. For operators, this underscores the importance of staff leadership not only as a safety issue but also as an envi- ronmental management tool. This suggests that reef-safe culture is contagious, both positively and negatively. Environmental Standards and Operator Practices The study also examined operators participating in Green Fins, one of the dive industry’s best-known environmental certification programs. Unsurprisingly, researchers found that operators with stronger environmental standards were associated with guests with lower documented reef-contact rates, par- ticularly in programs with more rigorous implementation.
that this is not an anti-diving study. Divers are often among the strongest advocates for coral reef conservation because they experience these ecosystems directly and form strong emotional connections to them. The key message is that even well-intentioned, low-impact activities can still produce unintended environmental effects. In our study, most reef contact was unintentional or unnoticed, which matters because you can’t address impacts you’re not aware of. The goal is not to discourage diving, but to support better div- ing.” Instead, the research highlights the growing importance of careful environmental management in heavily visited reef
But the nuance is important. The findings suggest that envi- ronmental certifications are most effective when integrated into daily operations rather than functioning primarily as marketing labels. Operators that consistently reinforce envi- ronmental briefings, actively supervise diver behavior, invest in staff training, and maintain appropriate guide-to-diver ratios appear better positioned to reduce reef impacts. Many professionals already recognize this intuitively. Reef protection rarely results from a single briefing or policy. It emerges from operational culture, staff consistency, and ongoing reinforce- ment. The Take-Home Message It’s important to recognize this study not as an indictment but as an opportunity. Ultimately, this study should not be viewed as an attack on scuba diving tourism. In many regions, dive tourism remains a strong economic argument for protecting coral reefs from destructive and extractive in- dustries. As the study’s lead author, Dr. Liu, has commented on the reaction to his work, “It’s really important to emphasize
systems. For dive operators and professionals, the findings offer an opportunity to refine practices that are already
moving in this direction such as: Stronger buoyancy training ▪ Better diver awareness ▪ More intentional wildlife management ▪ Thoughtful photography protocols ▪ Active in-water supervision ▪ Clear environmental leadership ▪
The dive industry has long played an essential role in marine conservation. As reefs face mounting global pressure, that role may become even more important. Protecting coral ecosystems will require not only passion for the underwater world but also continued attention to how divers interact
with the environments they come to experience, photograph, and ultimately help protect. Source: Lin, B. et al. (2026). Causes and correlates of un- sustainable scuba diving tourism on coral reefs.
