If you really want to save the reefs start contacting some of the agencies and insist on better buoyancy control standards for OW students. Dropping people in open water after a few hours in the pool, where no real buoyancy control has been taught (fin pivoting is NOT buoyancy control past pool session one) is one of the reasons you see so many standing, kneeling, bouncing off of and into reefs, wrecks, and each other.
