l fluctuations. In the case of the Belize Barrier Reef, many factors which make the distinction difficult do not apply. Human population in this area is much more sparse than the corresponding areas near other coral reefs, so the human activity and pollution are much lower compared to other coral reefs and the Belize reef system is in a much more enclosed area.
When coral bleaching occurs, a large part of the coral dies, and the remaining part of the ecosystem begins the process of repairing the damage. But the chances of recovery are low, as corals that are bleached become much more vulnerable to disease. Disease often kills more corals than the bleaching event itself. With continuous bleaching, the coral reef will have little to no chance of recovery.
