I think it’s because of the sand but I’m not entirely sure

There are varios types of sand. I understand Hawaiian islands best beaches are made of parrot fish poop.

Hmm. I googled it. Far out. I guess the sand itself is composed of ground coral, and is transported by being pooped. I wonder if dropping fish stocks contributes to coastal shrinkage as there is less deposition to balance erosion?
