Definition: What are coral reefs?

Coral reefs are diverse underwater ecosystems formed by colonies of tiny animals called coral polyps. These polyps secrete a hard calcium carbonate exoskeleton that provides a structural framework for the reef. Coral reefs are found in shallow, warm, and clear waters, typically in tropical and subtropical regions.

These intricate ecosystems are often referred to as the “rainforests of the sea” due to their high biodiversity and importance in supporting a wide range of marine life. They are home to a vast array of species, including fish, crustaceans, mollusks, and other invertebrates.

Coral reefs play a crucial role in maintaining the health and balance of marine ecosystems. They provide habitat, shelter, and breeding grounds for numerous species, acting as nurseries for fish and other marine organisms. Additionally, coral reefs protect coastlines from erosion by absorbing wave energy and reducing the impact of storms.

Unfortunately, coral reefs are facing significant threats due to human activities and climate change. Pollution, overfishing, destructive fishing practices, and coastal development all contribute to the degradation of coral reefs. Rising sea temperatures and ocean acidification, caused by greenhouse gas emissions, pose additional challenges to their survival.

Efforts are being made worldwide to protect and restore coral reefs through sustainable management practices, marine protected areas, and conservation initiatives. These initiatives aim to mitigate the impacts of human activities and promote the resilience and recovery of coral reef ecosystems.
