ok great. millions and millions of dollars. but who profits or wins the
most? not the local residents.
at least in mexico, most ecotourism business are owned by foreign citizens
and is not unusual that they have offices that contact the clients in the
USA or europe, bring them in US airlines, pick them at the airport and
drove them directly to hotel (owned by foreigners), and then take them to
the site under the care of guides born in the US (who many times are
working illegally in the country). in short the visitors have practically
no contact whatsoever with the local population, and spend a minimum
amount here; most of the money never even enters the country.
the thing here is not if ecotourism produces money, but who benefits from
it. when the locals receive their fair share, they will be happy and
actively collaborate in conservation activities (a good example is cabo
pulmo, in baja california). when they do not, they have no real reason why
to consider ecotourism as a real alternative. and in those cases I believe
that all our econometric studies miss the point.

>> Major changes began in the 1970s. First came the 36-inch water

>> Andrew in 1992. Fortunately, Andrew missed the heart of the Keys.

>> Mercedes and purchased fleets of boats and thousands of traps. Motels
>> and marinas enlarged and property values skyrocketed. Homes,
>> property, and boats were being bought with suitcases of hard cash
>> while beer trucks transported weed northward on US 1. Illegal aliens
>> flooded in, leading to creation of roadblocks on US 1. They were
>> usually right next to the Last Chance Bar and Grill. Inspecting car
>> trunks revealed the true extent of drug smuggling so periodic
>> roadblocks persisted. Roadblocks of course impacted tourism, leading
>> to establishment of the so-called Conch Republic in 1981. Creating
>> the Republic and threatening to secede from the Union was a joke but
>> the term Conch Republic stuck and proudly remains today. To avoid the
>> roadblock, smugglers could telephone the Last Chance Bar and learn if
>> one was in place. Some Keys politicians and public employees could
>> not resist easy money. Some roads to nowhere were constructed. The
>> one on Sugarloaf Key was covered with skid marks where small planes
>> landed to unload. It was a very different place worthy of many Jimmy
>> Buffett songs. A pirate turns 40 became popular.
>> The exact dates escape me but a Federal court ruling limited the
>> State's offshore jurisdiction to 3 miles on the Atlantic side of the
>> Keys. Pennekamp State Park could no longer protect the best reef
>> areas farther offshore. That change in Federal law provided an
>> opportunity for NOAA's new Sanctuary Program to take over
>> jurisdiction of unprotected offshore waters. By then, the National
>> Marine Sanctuary Program had been created under the Department of
>> Commerce to protect the site of the Civil War ship Monitor.
>> Establishment of that site was followed by a proposal to create the
>> Texas Flower Garden Reef Sanctuary; however, enactment took many
>> years because NOAA was up against Texas politics and the petroleum
>> industry. Sanctuaries were also being proposed in many areas
>> previously selected as potential oil exploration areas. There was
>> much angst within the petroleum industry and on Capitol Hill. But
>> that's another long story.
>> Meanwhile, the Key Largo Marine Sanctuary was created after
>> much wrangling, and State rangers were deputized to patrol both State
>> and Federal waters. I was on the boat and took photos of the ceremony
>> when John Pennekamp cosigned the official documents. At that time,
>> corals were almost pristine.
>> After the new water pipe, initiation of mosquito spraying, lack

>> became a magnet for out-of-state divers. They came in droves! Dive
>> shops sprang up, as did dive charter boats. The war with line-fishing
>> charter boats was over. Scuba diving became king!
>> Meanwhile, business leaders in the lower Keys took note and
>> looked longingly at the activity and money lavished on the upper
>> Keys. After some preliminary studies, NOAA next proposed
>> establishment of the Looe Key Sanctuary. Several long and heated
>> public hearings ensued. Most Conch Republic residents because of

>> As every coral scientist knows, the demise of the coral reefs
>> began in the late 1970s and peaked in 1983 and 1984. Coral bleaching
>> came to Florida later in 1986-87. Coral demise was occurring
>> throughout the Caribbean in the early 1980s, even around islands with
>> few people. The black-spined sea urchin Diadema suffered at least 90
>> percent mortality everywhere in the Caribbean. The urchins literally
>> died off in a period of one year during 1983, about the same year
>> seafan disease appeared. Many acres of elkhorn and staghorn corals
>> died within a few months adjacent to the Finger Lakes Marine
>> Laboratory on remote San Salvador, Bahamas. The rapid die-off that
>> happened in 1983 was well documented by the scientists at the Finger
>> Lakes lab.
>> In retrospect, 1983 and 1984 were the banner years for African
>> dust transport to the Caribbean as well as Acropora coral demise most
>> everywhere in the Caribbean. I am reminded that the sponge industry
>> suffered a similar Caribbean-wide demise in 1938 and later in the
>> Gulf of Mexico in the late 1940s. The causes of the sponge deaths
>> were not determined, and the events have long been forgotten. So what
>> really caused reef demise and the earlier sponge deaths? Could it be
>> a combination of factors? Many scientists and agencies seem to have
>> their favorite candidates that shift with time. They generally prefer
>> an activity such as anchor damage and boat groundings that can be
>> controlled through fines. Natural biological cycles or the African
>> dust hypothesis are not acceptable villains.
>> There is much we still don't know, and currently little research
>> is aimed at experimentally determining causes. Finger pointing will
>> likely continue until the coral bounces back and everyone can claim
>> victory. I admit this is a personal rather cynical history not likely
