RRI.CO.ID, Jakarta - Coral reefs cover less than one percent of the world's ocean surface, yet they are home to more than a quarter of all marine species. This fact makes coral reefs one of the most vibrant and valuable ecosystems on Earth.

The existence of coral reefs is not only about underwater beauty, but also affects the livelihoods of millions of people around the world. Hundreds of millions of people, including tens of millions of fishermen, depend directly on the health of coral reefs for their food and income.

Economically, coral reefs are a vital pillar of the fisheries sector in many coastal countries. In some parts of Southeast Asia, a large portion of fish catches are even highly dependent on healthy coral reefs.

In addition to providing food, coral reefs also serve as natural protection for coastlines from wave action. Coral structures significantly absorb wave energy, thereby reducing the risk of abrasion and the impact of storms and large waves on coastal areas.

In the tourism sector, the beauty of coral reefs attracts many tourists to dive and snorkel in various marine destinations around the world. These activities ultimately contribute to the economic development of coastal communities living around reef areas.

Coral reefs also hold significant potential in the health sector, a topic that scientists are still researching. Several organisms living on coral reefs are known to have the potential to be developed into therapeutic agents for various diseases.

Unfortunately, despite all their benefits, the world's coral reefs are facing serious threats from climate change, pollution, and destructive fishing. If these conditions continue unaddressed, scientists warn that most of the world's coral reefs could become extinct in the coming decades.

Given the significant role of coral reefs for marine life and humans, efforts to preserve them cannot be postponed. Protecting coral reefs today will determine the sustainability of food sources, the economy, and the balance of marine ecosystems for future generations.
