When its taken does it destroy reefs?
That is highly debatable, alot depends on where the LR
is taken from, it is supposed to be taked from the sandy areas, which is LR
that has been knocked off the reef structure by storms and wave action. Also non=aquacultured LR
is a renewable resource. However, I am sure that in some 3rd world countries that are feeding their people with the export of LR
....they have played fast and loose with the rules governing it's collection.
