## Resource

Sunscreen usage has risen exponentially over the last decade - and with summer finally here, Cecilia and Nethra are exploring the impacts of sunscreen on our bodies and marine life. How does sunscreen break down in our ecosystems? What is "Reef-Safe"? What are the solutions to the accumulation of sunscreens in our coral reefs and marine habitats? What is the difference between SPF 30 and 50? Definers, tune into this month's episode as we explore these topics and hear from our expert guest Katie Day , Senior Manager of Science and Policy at the The Surfrider Foundation . Special guests include Mike Malterre from Stream2Sea - a sunscreen company that is completely changing the industry and innovated a product to nourish reef ecosystems!
