What is the present status of the corals?

Not really good!

We, the humans, have overexploited the resources there besides destroying the poor beautiful creatures (corals) through mining and destructing methods of fishing. Pollution has also impaired the excellent ecosystem. Sometimes Nature also shows its fury through tsunami, earthquake and storm, and destroys them. Due to these reasons, almost 60% of the coral reefs, worldwide, have become degraded. About 10% of the reefs are irrecoverably damaged.
