Slathering on sunscreen at the beach? It may be destroying coral reefs

Studies show that oxybenzone, a common chemical found particularly in spray-on sunscreens, contributes to coral bleaching and leaves reefs deformed

For years we've been told to slap on sunscreen to protect against the harmful effects of the sun's UV rays. But eco-conscious beachgoers may want to take care with their sunscreen this summer, as studies show that many contemporary sunscreens pose a threat to the ocean environment.

Oxybenzone is a common chemical found in all types of sunscreen, but particularly in the spray-on variety, that researchers have found harms coral, and is in high concentrations at some of the most world's most popular reefs.
