Sun Screen Effects on Coral Reefs
Simply put, using coral-safe sunscreen is essential in protecting Hawaii’s unique and invaluable ecosystem. Many guests plan ahead by packing sunscreen, but certain types can be damaging to the health of our coral reefs. With traditional sunblock, water can wash away some of the oils, which then settle like a film on our coral’s delicate ecosystems.
The culprit of these damaging effects is the ingredient oxybenzone, used to filter UV rays, or preservatives such as butylparaben.
Recent research has shown that there are high concentrations of oxybenzone near the shores of Hawaii and in the Caribbean. The study found that between 6,000 and 14,000 tons of sunscreen end up in the world’s coral reefs each year. This film can infect or bleach an adult coral reef and be fatal to baby coral. The chemicals can even disrupt and change the hormones of our fish. This chemical has not been proven to be harmful to humans, however, it’s critical for us to do our part in protecting the reefs.
