Conservation 101: the Compete to Conserve Blog

For years we’ve been told by doctors to wear sunscreen to protect ourselves from the cancer-causing ultraviolet rays. Now it seems, this protection for humans may come at a cost. According to a report published in the National Institute of Environmental Health Sciences journal Environmental Health Perspectives, chemical ingredients found in most sunscreens can cause bleaching in coral reef and are accumulating in fish and other aquatic life.

An estimated 6,000 tons of sunscreen ends up in coral reef areas where people swim and snorkel. And because 60% of the world’s coral reef is threatened by rising sea temperatures, pollution, and excess UV radiation, the sunscreen issue is worth further study and action.

Here are a few ways you can do your part to limit these chemicals in our oceans and still protect yourself from the sun:

1. Wear a long-sleeved rash guard (swim shirt) so less skin is exposed and less sunscreen is needed. You can find UPF-rated clothing at surf shops or online at Coolibar and Athleta.
2. When not in the water, stay in the shade, so you’ll need to reapply sunscreen less often. Bring a beach umbrella and wear hat.
3. Wear sunscreen with biodegradable ingredients. (This is already a requirement in some protected areas in Mexico.) Avoid sunscreen that contains Benzophenone-3 (Oxybenzone), ethylhexylmethoxycinnamate (Octinoxate), 4-Methylbenzylidene camphor, and Butylparaben.

Brands such as Alba Botanica, Badger, Burt’s Bees, California Baby, and Keys Soaps carry sunscreens that don’t contain the ingredients above and can be found at many natural foods stores. But buyer beware: none of the suggested brands come in an SPF higher than 30, which for those with fair skin, can be an issue.
