What is coral bleaching? What factors lead to this?
What will be an ideal response?
Coral bleaching occurs when the dinoflagellate population in the coral's tissues cannot rebound. The coral dies, leaving its bleached hard parts behind.
Rising sea temperatures and sea level associated with global climate change most likely play a role. People also stress reefs by discharging sewage and other pollutants into coastal waters, by causing erosion that clouds water with sediments, and by destructive fishing practices. Invasive species also threaten reefs.
