Partially bleached coral in Kaneohe, Hawaii. Coral reefs worldwide are at risk of damage from the suncscreen ingredient oxybenzone.
New research about sunscreen's damaging effects on coral reefs suggests that you might want to think twice before slathering it on.
Reports about the harmful environmental effects of certain chemicals in the water have been circulated for years, but according to the authors of a new study released Tuesday, the chemicals in even one drop of sunscreen are enough to damage fragile coral reef systems. Some 14,000 tons of sunscreen lotions wind up in coral reefs around the world each year.
