I believe it could be industrialized quite easily. We are currently experimenting with using crushed glass bottles as a substrate and then transplanting the corals once they have established.

This allows us to kill two birds with one stone by recycling waste products and growing coral.

It is difficult to grow coral outside of the ocean, so the transplantation is very laborious. However this is where volunteer divers can be a huge assistance. The work is safe and easy, just time consuming.
