Reef Safe & UV Smart 

Submitted by Shelby Wood

If you haven’t seen headlines this week, there is growing concern over the stewardship and protective measures for the Great Barrier Reef. Just as the Upper Valley is beginning to see some summer weather, and our thoughts turn to time on the water, headlines like, “Unesco: Great Barrier Reef should be listed as ‘in danger'” (Khalil, BBC, 2021) and, “Australia rejects U.N. climate warning over Great Barrier Reef status” (Sulima, NBCnews, 2021) are a reminder that our day to day choices have a real environmental impact.  While admittedly the thought of reef bleaching can feel distant from New Hampshire lakes and beaches, there are some simple choices we can make collectively to be stewards of our environment. According to the National Park Service (2020) there are two simple things we can do to be reef safe: cover up and look at the labels on our sunscreen.

Many times while we’re at the market and need sunscreen for a trip to the beach or lake we might pick-up what’s on sale, or what the dermatologist recommended for SPF without thoroughly looking through ingredients. Consumer Reports notes that even consumers trying to be reef safe, only buying sunscreen with that on the label, may be duped into buying a sunscreen that still contains ingredients harmful to marine animals. How can that be? Consumer Reports (Calderone, 2021) notes:

But oxybenzone and octinoxate—two of the most commonly used UV blockers worldwide—aren’t the only ingredients that may be damaging to marine life.

How does that problem translate for us while shopping and comparing sunscreens? The article continues noting that, “the term “reef safe” doesn’t have an agreed-upon definition, and therefore isn’t strictly regulated by government.” (Calderone, Consumer Reports, 2021). If your Hawaii trip has been rescheduled, as of 2021, Hawaii has officially passed legislation banning the use of sunscreens that contain oxybenzone and octinoxate ( Back to the suggestions from the National Park Service, UV clothing is a win for the environment. Still need to make the dermatologist, and your skin happy? The advice on various websites can be overwhelming and at times specific ‘safe’ ingredients are safe on one website and questioned on another. For this reason, we’re sharing the more conservative information available through the Oceanic Society  :

 Choose a Reef Safe Sunscreen

When you do need to use sunscreen, or for areas that can’t be effectively covered with clothing, be aware that there are two types of sunscreen to choose from:

  • Chemical sunscreens: Products that frequently contain the absorbable and coral harming ingredients mentioned above. It is best to avoid these.
  • Physical sunscreens (also known as mineral or inorganic sunblocks): Products that use zinc oxide and titanium dioxide and are considered “safe” for use around coral reefs.* There is some new evidence suggesting that titanium dioxide may be safer for corals than zinc oxide. These are the best choice.       (Sentman, Oceanic Society, 2018).

As we all navigate finding balance between saving our reefs, and saving our skin,  I hope that some of the links listed below (works cited) will help inform and guide your quest. The video playing, “Reefs at Risk” gives an overview of both issues in a succinct way that I hope you find useful.
