Explained | Why Coral reefs damaged : All about I Drishti IAS

Coral reefs are essentially just big limestone structures built by thousands of tiny coral creatures called polyps. They’re found in more than 100 countries, and just like pina coladas, they belong in tropical areas. But they’re not looking too healthy. Increased ocean temperature caused by climate change is the main cause of coral bleaching events. That’s when reefs expel the symbiotic algae responsible for their color. If that happens over longer periods, the corals can eventually die. The planet has already lost about half of its shallow water corals in in the past three decades.
