The document discusses coral reef formation and the conditions needed for their growth. It describes different types of reefs like fringing reefs, barrier reefs, and atolls. It also discusses threats to coral reefs from natural causes like hurricanes and volcanoes as well as human threats such as pollution, blast fishing, and climate change. Global warming is causing bleaching events and ocean acidification which are major threats to coral reef ecosystems. Conservation efforts are needed to protect coral reefs from further destruction.
