I think there needs to be an Eco-Diver rating. It would be industry wide and would have stringent standards and if those standards are not met you do not get the rating. The rating would be required to dive any ecologically sensitive area such as a reef system.
People are all over the bottom because nobody has ever told them to get off the bottom. It is ignorance as much as skill or lack of I should say. Frankly, I think some of it it on purpose, they simply do not care. They are the most important thing in the universe. The diver culture needs to strongly discourage and essentially censor divers who damage reef or touch bottom more than a finger or who are always vertical in the water. People are social animals, social pressure is the solution to correcting bad behavoir.

I call that OW. This is a remediation class for those who did not get it during their OW classes. My OW students will never have to take this kind of class. I would rather see all the instructors set the bar a bit more neutral for their students. It's just not that hard to do.
The new PADI OW standards being implemented in 2014 emphasize this. Even in the pool sessions, students are to do an exercise where they pretend the bottom of the pool is an environmentally sensitive area. They must descend to and dive over that bottom without touching.
