💡Did you know that sunscreen can pollute entire ecosystems? If you want to protect your skin and those ecosystems, there’s a way!!
“Not only can it [sunscreen] bleach or deform corals, but it can also impair the growth of green algae, an essential part of the food web. The effects can be seen all the way up the food chain, even affecting at-risk species like the Hawaiian green sea turtle or honu. With an estimated 4,000 to 6,000 tons of sunscreen washing off into oceans worldwide every year, our coral reef ecosystems need your help!
Research shows that harmful sunscreen chemicals can negatively affect living organisms. So if you're thinking, but what if I'm nowhere near the ocean, think again! Chances are there will be living organisms in the lake you jump into or the stream you stop to soak your feet in. Always choosing reef-friendly sun protection can help protect the health of ecosystems beyond coral reefs and into our own backyards.”
Here’s how to find a safe sunscreen for your summer sun protection:
“Read the fine print. Check that tiny print on the ingredients label. Look for: Zinc Oxide & Titanium Dioxide (and nothing else!) Avoid: Oxybenzone, Octocrylene, Avobenzone, Benzophenone-1, Benzophenone-8, OD-PABA, 4-Methylbenzylindene camphor, 3-Benzylidene camphor, Homosalate, Octinoxate, Octisalate, and Nanoparticles
Slather don’t spray. Many spray sunscreens contain harmful nanoparticles.
Watch out for green washing. Some companies will take out just one harmful chemical and then slap on a reef-friendly sticker. Go the extra mile and check the ingredients to ensure your sunscreen is indeed reef-friendly.
Skip the mess and cover up instead. Choose UV-blocking clothing, hats, and sunglasses instead of smearing on the sunscreen.”
