7 Important Reasons to Preserve Coral Reefs

Coral reefs are indispensable to our planet, offering a multitude of benefits that extend beyond their vibrant beauty. These underwater ecosystems play crucial roles in maintaining marine biodiversity, protecting coastlines, and supporting human livelihoods. Understanding the importance of preserving coral reefs is vital for ensuring a sustainable future. Keep reading to know more!

Top 7 Major Reasons to Preserve Coral Reefs

Marine biologists refer to coral reefs as the ‘rainforests of the sea’ because of the high levels of diversity and the importance of the structures in the ocean. But their importance does not end there at the ocean basin. Below are seven key reasons why it is crucial to ensure that these underwater fortunes are protected at all costs: 

1. Biodiversity Hotspots

One of the major benefits of coral reefs is that they act as centres of species diversity. They are home to about 25% of all marine species such as fish, molluscs, and crustaceans. It is crucial for the preservation of the health of ecosystems and the balance of marine organisms and species. Coral reefs are the complex systems that provide the habitat, spawning grounds, and feeding zones that are essential to the numerous marine species.

2. Coastal Protection

These structures help in shielding the coastal communities from the effects of waves, storms, or even tsunamis. They decrease the impact of wave energy and in this way protect the coastlines from eroding, and people and property from being washed away. 

Coral reefs are important for regions that are normally affected by hurricanes and typhoons. Conserving the coral reefs means protecting the shelters and sources of income of millions of people inhabiting the coastal regions.

3. Support for Fisheries

Most societies in the global society depend on fisheries for food security and as a source of income. Tropical coastal waters are important for the breeding and growth of many fish species that are important for food and income. 

The uses of coral reefs include supporting the fish stocks that give protein to over one billion people around the world. Coral reef health is important for the continual supply of these fisheries as a source of income for coastal communities and as a food source for the world.

4. Tourism and Recreation

Coral reefs are beautiful and rich with various sea creatures, millions of tourists visit these places annually to enjoy the beauty of the reefs which in turn boosts the economy of the affected regions. Snorkelling, scuba diving, and glass bottom boat trips are some of the major activities in such areas. 

It is worth making a note that coral reefs play a crucial role in tourism, providing billions of dollars to the world’s economy every year. So protecting these natural attractions will continue to provide income generation for future generations.

5. Medical Discoveries

Coral reefs contain bioactive compounds which can be used to treat diseases and other medical conditions. Scientists have already found several crucial drugs based on reef organisms; these include anti-cancer, anti-HIV, and antibacterial drugs. This makes the reefs valuable to medical researchers as a source of natural products that are yet to be discovered.

6. Climate Regulation

Coral reefs participate in carbon and nitrogen cycles, therefore acting as a regulator of climate on the planet. They help remove carbon dioxide from the air, thus reducing the effects of climate change. The role of coral reefs in climate regulation cannot be underestimated, since these structures play a crucial role in maintaining the appropriate levels of these vital gases.

7. Cultural Significance

Indeed, according to the various indigenous and coastal people, the coral reefs are of great cultural and religious importance. They are commonly involved in historical activities, beliefs, and occupations. 

The significance of coral reefs therefore goes beyond the ecological and economic values of these structures and encompasses the cultural values of the people in these regions. Conserving the coral reefs is also about acknowledging and sustaining the culture and customs associated with the reefs.


The role of coral reefs is crucial, they are of great importance. Its advantages are numerous and affect bio-geological processes, shorelines, fish stocks, recreation, pharmacology, climatology, and anthropology. It becomes our duty as the inhabitants of this earth to protect such crucial habitats of our planet. When we save coral reefs, we are also saving the oceans and consequently, the planet and all the inhabitants in it.
