Coral reefs are considered the rainforests of the sea due to their incredible biodiversity and importance in supporting marine life. Just like rainforests on land, coral reefs are home to a wide variety of species, provide essential habitats for numerous marine organisms, and play a crucial role in maintaining the health of the ecosystem. Additionally, both coral reefs and rainforests are incredibly productive environments that support a rich array of life forms, making them vital components of the global ecosystem.
