What role do coral reefs play for coastal communities?

1. They serve as fishing grounds

2. They provide fresh water

3. They protect from storms and erosion

4. They contribute to tourism only

The correct answer is: They protect from storms and erosion

Coral reefs play a crucial role in protecting coastal communities from storms and erosion. These structures act as natural barriers, absorbing wave energy and reducing the impact of high-energy waves on shorelines. This helps to minimize damage during storms, reducing the risk to homes, infrastructure, and vital ecosystems located near the coast. In addition to offering protection, healthy coral reefs also support biodiversity, which can enhance local fisheries and indirectly benefit tourism. While they do contribute significantly to these other aspects, the core function in this context is their protective ability against natural hazards. By mitigating erosion and providing a buffer against storm surges, coral reefs are vital for the sustainability and safety of coastal communities.
