Issue:

When people drop anchors off shore to go scuba diving, the anchors fall and destroy the coral when they land.  That little bit of coral is destroyed instantly, but with the current, the anchor will drag and destroy coral for a long way.  It makes it very difficult to remove your anchor to because the anchor becomes caught under the coral, which makes it dangerous to yourselves if you try to leave.

Solution:

Use a mooring ball!  Mooring balls are conveniently placed near good diving spots.  All you have to do to use a mooring ball is to hook a rope and attach it to the front of the boat.  It saves the coral and is easier than anchoring.
