They City of Key West met on January 15, 2019 to discuss a ban on the use of sunscreens that contain the chemicals Oxybenzone and Octinoxate, two materials known to have detrimental effects on the reef ecosystem and has been found to be an endocrine disrupter. I had the chance to sit down with Mike Malterre of Stream 2 Sea, a mineral-based sunscreen company, to find out why this matters so much, and what his company is doing to change it.
