Ingredients in sunscreen having been doing damage to the coral reefs in Hawaii for years. These chemicals cause damage to the DNA of the coral, resulting in deformities, bleaching and sometimes even the death of the coral itself.
What's in the sunscreen that causes the damage?
In January, 2021 SB2571 came into effect in the state of Hawaii. This bill banned the sale of any sunscreen that contained oxybenzone or octinoxate (unless prescribed by a healthcare provider). The Hawaii State Department of Land and Natural Resources had banned the use of these sunscreens a year earlier in Kealakekua Bay. This specifically targeted the tour boats that operate in the bay every day.
Oxybenzone and octinoxate are both FDA-approved compounds and are present in approximately 80% of all sunscreens.
Sunscreens that also contain petrolatum, also known as mineral oil, often take years to biodegrade and are also harmful to marine life.
Coral reefs in the Hawaiian Islands are flooded with 6,000 tonnes of sunscreen every year.
It doesn’t take much to cause harm to the coral reef. Only a very small amount of oxybenzone (the equivalent of one drop of water into an area the size of 6.5 Olympic-sized swimming pools) can cause harm. Unfortunately, testing has revealed that some Hawaiian beaches show levels 10 times that amount.
Impact from sunscreen chemicals is only one factor among many causing ongoing damage to marine environments. Ocean acidification, water pollution and rising sea temperatures are all causing systemic problems to the ecosystem.
More changes ahead
In January 2023, a new law will ban the sale of sunscreen containing the ingredients avobenzone or octocrylene.
Maui has also passed a law which will come into effect October 1st, 2022 which will ban all non-mineral sunscreens.
