Coral reefs are complex underwater ecosystems formed by coral polyps, tiny organisms that build calcium carbonate structures over time. They are often referred to as the 'rainforests of the sea' due to their high biodiversity, providing habitat for numerous marine species. Coral reefs play a critical role in coastal protection from storms and erosion, and they support fishing industries and tourism. However, they are increasingly threatened by climate change, pollution, and overfishing, making conservation efforts vital for their survival.
