Choose Coral Reef Safe Sunscreens

South Florida’s coral reef is one of the longest and most heavily visited in the world. Excited crowds head out to this gorgeous, but sensitive, living structure in increasingly greater numbers. How lucky we are to have such a breathtaking natural area on our doorstep. But like so many things, good fortune is tinged with hidden responsibilities. Recent studies indicate that commonly used sunscreen ingredients can harm coral reefs. What follows is a brief summary of the current science on coral impacts from sunscreens and what alternatives exist to keep both the reef and our skin safe. Use Reef Safe Sunscreens.

First, a little chemistry. One commonly used ingredient in particular is harmful to coral reefs. This chemical is oxybenzone (BP-3), which is used in more than 3,500 sunscreen products worldwide. There are several other problem ingredients, but BP-3 is the most common. Scientists studying the impacts of BP-3 on corals have found that this active ingredient can cause bleaching, damage DNA and result in hormone imbalances. Scientists have found that this chemical has impacts on developing juvenile corals. Their studies documented young corals encasing themselves in their own skeleton and dying. In hard corals this chemical can cause coral to develop viruses. Once they become infected, their life-giving algae is expelled from the coral, resulting in bleaching. These responses can be triggered by very small amounts of this chemical. How small? Imagine one drop of water in six Olympic-sized swimming pools; that is enough chemical to cause some damaging effects to these animals. Thankfully, we can play a big part in the solution.
