This special day was first created in 2014 to raise awareness about the importance of our planet's coral reefs and the threats they face. Coral reefs are some of the most diverse ecosystems on Earth, providing habitat for countless species of fish and marine life. They also help protect shorelines from storms and provide economic benefits through fishing, tourism, and more. So let’s work together to protect our oceans and their amazing coral reef habitats!

WHY THIS DAY MATTERS

Why World Reef Awareness Day is Important

Reefs are a source of food

In certain parts of the world, reef systems provide an important source of food for millions of people. From shellfish harvesting to sustainable aquaculture practices, coral reefs are vital to local economies and livelihoods around the globe.

Reefs are essential to ocean health

Reefs are an essential part of a healthy marine ecosystem. They provide habitats for countless species of fish, plants and other marine life, as well as act as natural filters that keep our oceans clean. Without healthy coral reefs, the ocean's biodiversity would be drastically reduced.

Reefs protect coastlines from erosion

Healthy reefs act as natural barriers that can help to protect coastlines from the destructive effects of storms and rising sea levels. By preserving these fragile ecosystems, we can help keep our coastal areas protected and reduce the risk of damage during major storms.
