 人ならずサンゴを白化Coral: Palau to ban sunscreen products to protect reefs,BBC News,18.11.1

   Scientists have been raising concerns about the impacts of sunscreen products on marine life for many years.

They are particularly worried over the role of two ingredients called oxybenzone and octinoxate. These are used as sun protection factors as they absorb ultraviolet light.

However, they are believed to make coral more susceptible to bleaching. Research published in 2015 showed that the oxybenzone could stunt the growth of baby corals and was toxic to several different coral species in laboratory tests.

"Oxybenxzone is probably the baddest actor out of the 10 chemicals that have been banned," said Dr Craig Downs, an expert on the impacts of sunscreens on marine life.

"It causes corals to bleach at lower temperatures, and it reduces their resilience to climate change."

Dr Downs says that when there's a disastrous event like mass coral bleaching, reefs should recover over the following years. That has not been happening in many parts of the world.
