On the island of Maui alone it’s estimated that 55 gallons of sunscreen are dumped into the water every day. No sunscreen is best for reefs, but some types of sunscreen have ingredients that are worse than others and that can cause coral bleaching. Now environmentalist groups and lawmakers are proposing a bill that would prohibit the sale of sunscreen with oxybenzone and octinate in them, two chemicals that bleach corals white and inhibit the growth of sea life. If successful, Hawaii will become the first U.S. state to prohibit the use of certain sunscreen that scientists say harm sea life.
