There are plenty of tourist activities in beautiful Hawaii, and exploring the coral reef is one of the most unique. While the coral is lovely to look at, many people don’t realize how important the coral reef is to the ecosystem. Here’s what you should know about Hawaii’s coral reefs to help preserve them.

How It Helps the Ecosystem 

Coral serves as food and shelter for marine life like fish, lobsters, octopuses, and crabs. Over 500 species of algae live on the coral, providing food and oxygen for the reef inhabitants.

The reefs protect Hawaii’s beaches as well. They disperse the force of the waves to prevent shoreline erosion. The beach sands are also made up of dead fragments of corals, shells, and calcified algae.

These beaches attract visitors, and the reef itself hosts tourist activities like snorkeling. Hawaii earns $800 million in revenue from the marine tourism industry alone.

Why It’s In Danger

While tourists have benefited Hawaii’s economy, they’ve also contributed to the deterioration of the reefs. Some people may step on and damage the reefs while swimming or snorkeling. Waste dumps from cruise ships can also harm the reefs.

The main culprit for the deterioration of the coral reef is chemical runoff from lawns, farms, septic tanks, and other waste generators. When it contains sediment like soil, it can also block out sunlight and crush reefs. 

The nutrients in sewage and fertilizer can cause algae to overpopulate as well, which reduces the reef’s access to sunlight and smothers the corals.

How to Help

Try not to use a lot of fertilizers, pesticides, or products that contain chemicals and may run off into the sea. Likewise, refrain from throwing trash in the water or littering on the beach.

When you partake in water activities like snorkeling or surfing, avoid stepping on the coral reef.

If you want to participate more directly with reef preservation, there are plenty of volunteer opportunities, like beach cleanups.
