Calling your opinion self righteous is not a personal insult. A personal insult is attacking the person, not the issue (for example, calling someone an a-hole). I respect your opinion, and am debating, not attacking. Don't be insulted.
I find it interesting how you constantly pull quotes and then comment on them, when in the very next sentence, I say the same thing you are trying to prove. Example:
Sorry to break it to you, but the reefs do not need humans to thrive.
-They do in the year 2002. The reefs are being destroyed by human beings, it will take humans to save them.
We are the cause of the problems, not the solution, and the best thing people could do is leave the reefs alone.
Measures could be taken and laws could be passed to make humans less detrimental to reefs, such as the ban on collection of live rocks in Florida, but we are protecting the reefs from our self. If you think that the demand you create is really saving the reefs than you are just self righteous.
I am also saying that humans are destroying our reefs, and that it will take humans to save them. That is what I mean when I say that we need to protect the reefs from ourselves. I'm sorry if we didn't use the same terminology. In the future, I would appreciate it if you stuck to the big picture, rather than approaching each sentence as an entity in itself, especially when the next sentence proves your point. We are arguing in circles.
Now for what we are discussing....whether economics is a driving force for preservation. IMO, it isn't. It is a beautiful notion to think that uneducated poor fish collectors living in third world countries will join hands and decide to save the reefs. But in reality, this is not whats going to happen. If your livelyhood depended on catching fish, and being destructive meant more food on your family's table, you wouldn't stop to think that maybe you should do it a little more eco-friendly and catch a little less fish for the sake of the environment. Economics has existed for a long time, and the same principles that existed years ago, still exist today .... demand=supply. You mention that dynamite fishing is a bigger cause of destruction than aquarium fish....It absolutely is. But if what you say is true, then these dynamite fisherman should have stopped this extremely destructive practice decades ago. The same principles should exist for these fisherman, and even for the cruise industry...is this not true?...they all depend on the reef to make money.
In many places, dynamite fishing has stopped, but it is almost always thanks to the government banning, and not the fishermen choosing to do so. If one fisherman stops dynamite fishing, he is giving competitors the upperhand, just like it would be to stop destructive fish collection. IMO, the best way to stop this destruction is by either the government banning it, or us, the consumer, stop demanding it. If there is no demanding these fish, then there is no reason for people to go out and catch them.
And, for the record, I still think that it is self-righteous to believe that by buying fish caught in a destructive manner, you are somehow promoting change and in the long run helping the reefs.
