Stopping global warming only way to save Barrier Reef: Study
Australia-based researchers have raised concerns over large-scale coral deaths due to bleaching caused by global warming. The study found that 91% of corals on the Great Barrier Reef had suffered from bleaching over the past two decades. Bleaching, caused by underwater heatwaves when corals expel the algae living inside, turns corals white and makes them vulnerable to fatal diseases.
