The Unseen Impact of Sunscreen on Our Planet
When we think of pollution at sea, we often consider oil spills, plastic waste, or industrial runoff. However, another, seemingly innocuous product is making a devastating environmental impact: sunscreen.
Sunscreens are primarily designed to filter ultraviolet light from the sun, which protects our skin from premature aging and skin cancer. By doing so, many commercial sunscreens use chemicals. While these components are beneficial for human skin, they can have harmful effects on marine life, particularly coral.
A study published in the journal Environmental Contamination and Toxicology found that a small amount of sunscreen — equivalent to a drop of water in an Olympic-sized swimming pool — is enough to cause coral bleaching.
Oscillating Impact of sunscreen on Marine Life
When swimmers wearing sunscreen go into the water, it washes off and floats on the water’s surface. Many sunscreen compounds are then absorbed into the water, affecting marine life.
Among the most damaging compounds are oxybenzone and octinoxate. These chemicals can cause coral DNA damage, making the corals less capable of withstanding climate change. They disrupt coral reproduction and growth, leading to bleaching.
This impact extends beyond corals. Oxybenzone can also harm algae, sea urchins, fish, and mammals. It can deform and damage vital parts of young green sea urchins and also accumulate in the tissues of some species, leading to harmful effects.
Coral reefs play a crucial role in aquatic ecosystems. They feed and provide shelter for a large number of species, protect our coasts from large waves and storms, and support local economies through tourism and fisheries.
Making the Switch to Environmentally Friendly Sunscreen
Taking into account the eco-system harming impact of conventional sunscreens, it’s time for us to consider environmentally-friendly alternatives.
Look for Mineral-Based Sunscreens
Mineral-based sunscreens, which contain zinc oxide or titanium dioxide, are generally safer for marine life. These minerals are not linked to coral damage.
However, it’s worth noting that ’nano’ or ‘clear’ zinc or titanium products should be avoided as they contain tiny particles that could be eaten by corals.
Seek Out “Reef Safe” Labels
Reef-safe sunscreens are becoming more popular. These products are free from oxybenzone and octinoxate, the two main culprits damaging coral reefs.
However, keep in mind that the term ‘reef-safe’ isn’t regulated, so it’s always a good idea to check the ingredients list.
Opt for Non-Nano Products
Products labelled as ’non-nano’ have larger particles that cannot be ingested by corals.
Avoid Spray-On Sunscreens
Spray-on sunscreens are more likely to end up in the sand, where they can easily wash into the ocean.
Opt for Water-Resistant Sunscreen
Water-resistant sunscreens are less likely to wash off when you swim or sweat, reducing the amount of sunscreen in the water.
Support Brands that Care about the Environment
Many brands work actively to protect the environment. Supporting these companies means that part of your money usually funds conservation efforts.
