Im very sorry that divers sometimes get paper cuts to their skin, or usually the fingers, what do you think you have done to that coral that you innocently brushed up against? You broke the SML of the coral, opening up a channel to pathogens, which could kill that coral. In the Florida keys, every year, they have a mini season for lobster, I and friends of mine, have witnessed first hand people turning over coral heads to get the lobsters, they don't care, they wanna be the big guy capturing more lobsters than anyone else on the boat, I'll bet, that they even bet on who is going to bring in the limit, and the biggest lobster, this is just one example mind you, I also agree that climate change ie, warming sst's and ocean acidification are a bigger threat. Corals today are under a tremendous amount of pressure from many sources; pollution, warming sst's, acidification, physical impacts from vessels and divers and snorkelers, destructive
fishing practices ad infinitum, so, where do we start, do we talk to the politicians in Washington about reducing CO2 emissions , do we mention that as the arctic permafrost thaws, it releases tons of methane into the atmosphere? If we are going to save the reefs, from extinction, which is a possibility, it is going to take a global effort, reducing one stressor, is at least a beginning, who knows it may lead to others when the diving public realizes that coral reefs are dying all over the world, how do we accomplish that? I don't know do you? you know we scientist always talk about having a better informed public, I don't think we are very good at it!

Agreed.
There are often calls for new laws and regs to protect ocean resources, but
possibly more importantly we need to properly implement the existing laws
and regs already on the books.
Good to see NOAA saying no to the GA Aquarium's request.
If we are just as vigilant with the implementation of all laws that dictate
the resources NOAA is entrusted to protect the world's oceans will be the
better for it.

Dear coral-list readers,
I am a snorkeler of many years and recently, 2011, a scuba diver.? I too find myself getting really close to life on the reef for pictures.? Some rather amazing shots are all over a reef.? I have been on one reef, and I don't recall which one it was, where the rule getting off the boat was no gloves allowed.? When I asked why I was told that without gloves people touch so much less.? These guys are right.? I've never used gloves and I always dive in a shorty wetsuit..? Yes, I admit that once in a while I might brush, ever so lightly against a fragment of coral and I receive the nastiest of paper cut like injuries.? I'm not being silly here, these little things are more than annoying, they sting and last for days.? They are clear motivation to extend every effort to stay off the corals, don't touch anything.? Wearing gloves and a full wet suit might will allow me to survive being clumsy, no gloves and a shorty and you bet I'm keenly aware of my
every movement near the corals, and everything else. This practice of no gloves could be extended to no full style wet suits allowed.I advocate the no gloves and shorty wetsuits along with effective buoyancy control.? Respect the reef or come back with raser cuts that won't heal for a week.
The ability of coral to cut, and other things to sting you is no mistake in evolution, it is to these delicate creatures survive by creating an incentive for other creatures to not disturb them.? Let's get that incentive working for their survival along with all the other protective and restorative actions we might find appropriate.

Dear Francesca,
Your characterization of the average modern-day recreational diver is
broadly accurate and I would add that many in the diving industry are
complicit in developing the stereotype. It is currently the popular image
that the industry chooses to project and sell. You are also correct to
assume that we can?t expect dive operators to chastise their clients for
expanding their carbon footprints by traveling to dive in remote locations
spewing CO2 all along the way. At the same time, there may be effective ways
to change the paradigm if we can first come to recognize that transformation
is required. A responsible approach need not be self-defeating. I believe
that we can continue to enjoy diving on healthy reefs in wild blue oceans,
maintain a high standard of living and resolve these problems.
The diving industry must first have the courage to lead by openly
recognizing that prompt action is called for on both the local and global
levels to deal with land-based sources of pollution, sedimentation,
over-fishing and climate change. They can encourage divers to work to
improve their diving skills and knowledge of coral reef ecology; reduce
their emissions through simple actions like driving more fuel efficient
vehicles, changing to CFL or LED light bulbs, powering down electronics,
using less water, and recycling. And perhaps most importantly, a responsible
diving industry can encourage divers to support business and political
leaders who actively promote policies that will shift our world towards more
renewable, sustainable energy production. If just these simple steps can be
implemented, we will have moved in the right direction towards preserving
valued coral reefs for generations to come.
Regards,
Steve

>Several posters mentioned that divers do dive cause they like what they see
and thus they are inclined to protect it.. Unfortunately I have a different
experience and unless I am diving with scientists or researchers I haven't
noticed any above average environmental sensitivity among recreational
divers than the one you could detect among those sitting under an umbrella
on the beach. The main drivers for nowadays mass recreational diving, I have
found, are depth records, big fishes sightseeing often wishing they were in
a plate or on a hook, "I dive so I am cool" kind of attitudes and maybe
photography. Of course there are exceptions but I do not expect divers
campaigning or acting to save reefs more than someone sitting at home
watching documentaries, but likely I am wrong.
>
>Also I can't imagine diving operators telling their customers they
shouldn't have flew to that site, taken that boat, stayed at that resort and
eaten fish for dinner or at least that they shouldn't do it that often, nor
lobbying the government to quit oil subsidies and account for its
externalities so the price will raise and better represent oil true cost.
>
>What kind of stewardship are we expecting from them? Having them asking
someone else to reduce their footprint than themselves or their clients? If
so, who and in which way? I am sincerely wishing for an answer that would
maybe relieve some guilt from taking a plane and go diving somewhere and be
more effective than buying carbon offsets.

Wow Francesca,
That's a very cynical view of the recreational diving community.
Even here in PA, many dive shops have the pamphlets about sustainable
seafood choices. Every dive shop I dove with stressed buoyancy
control in terms of protecting reefs.
You claim that most divers have the environmental awareness of a
beachgoer under an umbrella. Well, then isn't it your responsibility
to strike up a meaningful conversation on the dive boat about issues
you find to be salient to that dive? If you mention some scientific
qualifications to the divemaster, I guarantee that he or she would
embrace the idea of you leading an environmental awareness discussion
en route to or after the dive.
I've noticed that many environmentalists act like evangelical
Christians regarding climate issues...and it turns people off or
against them. Just like an annoying guy shouting about the end of
the world on street corners, or the angry person explaining that you
will go to Hell for dancing, singing, being Catholic, or watching The
Brady Bunch, many environmentalists fail to understand that reasonable
conversation, not disdain and condemnation, are how to bring about
individual level change.
Discuss how fossil fuel use disrupts a specific dive site. Talk about
the drop in species, often an easily understood concept. Show how
plastic bags kill turtles, or temperature impacts coral development.
Just don't be that cynical angry environmentalist who thinks that the
rest of their dive partners are ignorant oafs under that umbrella.
Divers are receptive and care deeply. Sometimes we just don't have
the scientific background because science isn't our day job. Be
nice!

Unfortunately I have a different experience and unless I am diving with scientists or researchers I haven't noticed any above average environmental sensitivity among recreational divers than the one you could detect among those sitting under an umbrella on the beach. The main drivers for nowadays mass recreational diving, I have found, are depth records, big fishes sightseeing often wishing they were in a plate or on a hook, "I dive so I am cool" kind of attitudes and maybe photography. Of course there are exceptions but I do not expect divers campaigning or acting to save reefs more than someone sitting at home watching documentaries, but likely I am wrong.
