Snorkeling Tips: Protecting Coral and Wildlife
If you’ve ever snorkeled or scuba-dived in a healthy coral reef, you’ve likely been captivated by the vibrant marine life just below the ocean’s surface. Shimmering fish, sea turtles, starfish, sea horses, and octopuses all rely on these stunning underwater structures, formed by tiny living creatures called polyps.
Sadly, coral reefs are rapidly dying. Since 1950, about half of the world’s coral reefs have perished, with scientists predicting a possible decline of up to 90%. This devastation is due to pollution, unsustainable fishing, coral harvesting, and climate change.
Despite human impact on coral reefs, experiencing their beauty firsthand can inspire efforts to protect them. By following some simple guidelines, you can enjoy snorkeling without causing further harm to these delicate ecosystems.
Look, But Don’t Touch
Coral is extremely sensitive, and even a gentle touch can damage it by removing its protective mucus or transmitting diseases. Some coral species can sting, and other reef inhabitants, like sea urchins, have venomous spines. For your safety and the reef’s, keep your hands to yourself while diving.
Avoid disturbing the ocean floor as well. Kicking up sediment can harm coral and other marine life, particularly filter feeders.
Feeding wild marine animals is harmful; their bodies aren’t designed to process human food, and they may become dependent on it. Swim above the reef without making contact, take pictures, and enjoy observing the marine life without interacting.
Choose Reef-Friendly Products
Wearing reef-friendly products is essential. Many commercial sunscreens and skincare products contain chemicals that harm coral reefs. Ingredients like oxybenzone, octinoxate, and avobenzone can cause coral bleaching, DNA damage, deformities, and even death. These chemicals can also harm algae, mussels, sea urchins, fish, and dolphins, leading to reproductive issues and deformities.
Each year, an estimated 14,000 tons of sunscreen end up in the ocean. Protect yourself from UV rays with mineral-based sunscreens that use physical UVA and UVB filters. Avoid products with micro-plastics and ingredients harmful to marine life. Instead of relying on labels that claim “reef-friendly,” check the ingredient list yourself.
Additionally, consider wearing UPF protective clothing like shirts, leggings, sunglasses, and hats. These options not only protect you from the sun but also minimize the need for sunscreen.
By taking these precautions, you can enjoy the wonders of coral reefs while helping to preserve them for future generations.
