How do coral reefs benefit us?

Coral reefs are underwater ecosystems that are not only beautiful, but extremely important to marine life. Not only do they serve as homes for marine animals, they are actually beneficial for human life as well. Coral reefs serve as barriers and buffers to coastlines and shores, protecting them against large waves, floods, and storms. Without the reefs, coastal communities can experience devastating damages to their property. However, coral reefs are being devastated every day by water pollution.  Water pollution allows for damaging algae to grow on the coral, as well as making it more susceptible to disease. Preventing water pollution comes back to the same basic principle: be aware of what you dispose of, how you dispose of it and be mindful of your plastic consumption habits.

 

Coral Reefs vs Sunscreen

Something that harms coral reefs that isn’t as publicized may come as a surprise to you. Have you ever thought of yourself directly impacting coral reef health just by swimming in the ocean? According to the Coral Reef Alliance, sunscreen has a direct link to decaying coral health. Most sunscreens have a chemical called oxybenzone, which is used to protect skin from the Sun’s UV rays. While it might benefit us, it doesn’t necessarily do the same for these coral reefs. This chemical has a direct link to bleaching coral, causing coral deformities, damaging coral DNA which affects reproduction, and disrupts natural coral hormonal processes. Some alternatives to popular yet damaging sunscreen are listed by Travel and Leisure. One that I’ve tried personally is Kokua Sun Care, which is a natural, zinc based cream that doesn’t harm marine life!

What can you do to protect coral reefs?

The EPA lists several ways you can help save coral reefs, and many of them start at home. First, when you’re on vacation and visiting these magical reefs, be mindful of your snorkeling and diving habits. Do not touch the reefs, and avoid anchoring boats to them, seeing as they are delicate and this can kill them. At home, there are plenty of ways you can help the reefs. One is by minimizing the use of fertilizers. Some of the nutrients found in these fertilizers, such as nitrogen and phosphorus, are harmful pollutants and can destroy coral when introduced into the ocean. Another way to help is to reduce stormwater runoff. Using rain barrels to collect rainwater not only helps prevent flooding and diverting water to storm drains, but it is a resourceful way to water gardens and indoor plants.  Finally, a last method is spreading the word. People are aware that ocean pollution affects all kinds of marine life, but coral reefs are rarely mentioned. These reefs, while they don’t make up a big portion of ocean life, are extremely important ecosystems that are home to sea sponges, crustaceans like crabs and shrimp, and starfish, just to name a few.

Do your duty as a human living on this beautiful planet and help out as much as you can!
