Coral Bay, located on the breathtaking Ningaloo Reef, is a marine wonderland known for its pristine coral ecosystems and diverse marine life. This small Western Australian coastal town attracts marine enthusiasts from around the world, offering unforgettable experiences in diving, boating, and snorkelling. However, the fragile balance of this unique ecosystem is increasingly under threat—not just from global factors like climate change and pollution, but also from everyday products like sunscreen.
As more coastal visitors enjoy the beauty of Coral Bay and similar locations, it’s essential to make environmentally conscious choices, such as using reef-safe sunscreen. This simple switch helps protect not just the coral, but also the marine life that depends on these ecosystems. By choosing reef-safe products, you’re actively contributing to the preservation of Ningaloo Reef’s vibrant underwater world.
Why Choosing Reef Safe Sunscreen is Important
Studies have shown that certain chemicals commonly used in sunscreens can have harmful effects on coral reefs.
They may:
Impair coral growth and contribute to bleaching events
Disrupt coral reproduction,
Affect the hormones of fish and other marine life
Lead to reproductive issues and birth defects of marine life
Studies have shown that even small amounts of sunscreen can have a significant impact on marine ecosystems.
So, what can you do to help protect Ningaloo Reef?
Choose mineral-based sunscreens. Mineral-based sunscreens, such as those containing non-nano zinc oxide or titanium dioxide, are generally safer for the environment than chemical-based sunscreens.
Watch out for zinc oxide and titanium dioxide when they are labelled as nano particles as they can be dangerous for you and marine life at this size
Apply sunscreen sparingly. The less sunscreen you use, the less likely it is to pollute the water.
Consider wearing protective clothing such as rashies, wetsuits and hats to minimize your exposure and reduce the need for sunscreen.
Allow time between applying sunscreen and entering the water to reduce chemical runoff.
