Why would that amaze you? I was told once that the average "diver" makes
no more than a couple dozen dives his entire life. Many "divers" get no
more than ten dives in a year max. These aren't divers any more than I'm a
musician because I plunk on my guitar when I have nothing better to do.
And those kind of "divers" know no more about coral ecology and
anthropogenic activity than I know about major/minor chords and tempo.

I have a question of my own. Why would you expect the average diver to be
any smarter or responsible than the average tourist?

I can offer a long term perspective on poor reef management. The west
coast of Maui (a Hawaiian island) has suffered classic and dramatic
degradation of its reefs over the last dozen years. Corals have been
smothered with repeated algae blooms.
Repeated algae blooms by the way, that management/newspapers DENY existed
except in 1989 and 91.
I wrote a reporter and asked him what in the world they'd define as a
"bloom". And here was the response.
"In the case of defining what is a "bloom," we rely on what we consider the
So you can be a diver underwater up to your armpits in green slime and it
isn't a bloom.
For example, this from Summer 2000 is NOT a bloom! The technical experts
say so. Can you see my husband?
Next, this summer one of the most popular dive sites on Maui --a place
called "Airport Beach" had algae smothering its corals.
And here's what the corals look like right where divers and snorkelers get
in and out of the water
And you know something? Most people come out of there thinking it looks
great. Cool fish around. They might even see a hawksbill (we did when
there). They're happy.
They don't know what Airport Beach looked like before and besides, it's WAY
better than anything they have at home. And the ocean from the beach is
still blue and beautiful.
The people who should be squawking are the tour master-divers there. That
is, the dive industry proper. Yet, far as I can tell they're mute.
Back in 1991 when I first complained about the massive algae problem in
I warned people that the slime would affect tourism.
But I was wrong.
This summer I actually watched two couples sit with their lounge chairs
directly in the Cladophora algae on the beach (thick and slimy) allowing
waves to rock them. They were laughing up a streak while drinking
beer. From the intensity of their laughter I suspect that in addition to
alcohol, their moods were also "enhanced" by Maui-Wowie as well.
And when I saw that? Them sitting in slime like that? I concluded that
people can handle all manner of coastal decline. Humans will swim in their
own swill. So long's the destination swill is better than their home swill.
And the tourist industry knows this. And so do the politicians.

Unfortunately too many people ARE.
