How to Rebuild a Reef
Many threats face coral reefs today, from coral bleaching to storms to boats and anchors that break fragile coral branches. But all hope is not lost - corals are capable of regrowth. Recently, a great deal of research has gone into understanding coral resiliency.
Corals take at least several decades for regrowth and it is a slow and steady process. Naturally, it is important for coral to have evolved the ability to rebuild and regrow because natural disasters like storms and variations in fish grazing happen all the time. The problem now is how corals can regrow in the context of human-caused environmental change.
