Well that all makes sense about the making glass from the sand (they've got plenty of it) and confirms all of our suspicions on local mining. Something about buying a warehouse of furniture just seems silly, but that's besides the point.

Harvesting coral to make counter and tabletops is cringe-worthy, but I suppose it could be done in a responsible manner. I could totally picture the gorgeous "twin fish" tables from the Kashmir Restaurant being made from the brilliant corals seen in Bio2. Coral is also used in medicine and precious jewelry, so it makes sense that it'd be utilized.

As for recycled sunken ships...again, silly sounding, but useful. Although, the materials from them would constitute a very small portion of Rapture's resources.
