In our February issue, we wrote about turning oil
rigs into diveable reefs, and why, even though leaving
rigs in the water is the cheapest and often cleanest
option, some environmentalists are clashing with
coastal state governments about keeping them in the
water. The opposition also carried over into our readership
-- we got a few letters showing that some readers
also stand on one side of the fence or the other.
Kevin McCarter (Aurora, IL) thinks the anti-reef
  environmentalists are hypocrites. "It seems to me this
  segment of the environmentalist crowd is among the
  most pig-headed, stubborn, emotionally driven people
  on the planet. They're not open to true, data-driven
  science or common sense. There's simply no balance
  in their world view. To them, it's all about politics and
  money . . . Your quote from the Greenpeace "executive"
  that fighting reefing is still the right thing to do because
  the oil companies don't like it is a rare bit of honesty that
  completely exposes their approach. Unfortunately, their
  top priority is not the environment. Don't get me wrong
  - - I don't automatically hate environmentalists. Aren't
  we all really environmentalists? I want to see the oceans
  and other parts of the planet protected against human
  activity, but I just want to see some common sense, balance
  and true scientific principles consistently applied."
Mary Wicksten (Bryan, TX) says our article is off
base and advises us to read Richard Rezak's book
  Reefs and Banks of the Northwestern Gulf of Mexico. "By
doing so, you'll find that many of the Gulf's 'natural
reefs' are less than 10 feet high, silt covered and/or too
deep for divers. For fish that prefer to get out of the
silt, the platforms are a blessing. But comparisons with
true coral reefs are useless. The platforms are shaded,
which discourages coral growth. They also are made
of metal parts that will not last hundreds of years.
What this all boils down to is that one is comparing
the biology on a metal vertical structure with that of
a muddy sea floor or a natural reef. Is the biota of a
platform 'good' or 'bad?' This is largely a matter of
opinion, not science."
Here's another option to consider: turning old oil
  rigs into posh hotels. That's what happened with the
  Seaventures Dive Rig Resort on Malaysia's southeastern
  coast, between the islands of Mabul and Kapalai.
  The resort features 25 rooms, from four-bed dormitories
  to twin and double rooms, and on-site amenities
  include a movie room, karaoke lounge and bar ( the
  dive instructors moonlight as the house band, the
  Sea Gypsies), and conference facilities. No dive boat
  needed: An elevator takes divers all the way down
  to the house reef, or you can get off at the Rig Jump
  platform and jump right in. Book your rooms at
