A newly published report says sunscreen harms coral reefs. Corals are animals that live in the oceans and seas. Sometimes they are called the rainforests of the sea. They create some of the most diverse ecosystems on the planet. Their great spread of colorful rock-like structures form exoskeletons in the water. The exoskeletons become homes to other very tiny ocean animals. But, pollution, warming seas, overfishing and sunscreen are destroying corals. John Fauth is a biology professor at the University of Central Florida. He is also a scuba diver. Fauth says the chemical in sunscreen called oxybenzone is harmful to corals. The chemical blocks the sun’s ultraviolet light—the substance that causes sunburn. Fauth and his team did toxicology studies on oxybenzone. He says they showed that the chemical causes the exoskeleton to turn white. He says it also damages the adult coral’s DNA. And, he says that genetic damage hurts the development of very young coral. John Fauth says oxybenzone affects more than the coral alone. He says it also hurts all the creatures that depend on the reef for homes and food. The scientists suggest that people use sunscreen without oxybenzone. He says people can also protect their skin by wearing wetsuits or other clothing in the water. The scientist says that would help protect individual corals, the reefs they form, and the animals that make their homes there.
