As I flew into the Maldives, President Nasheen was going public with plans to make the Maldives the first country in the nation to go "carbon neutral" by 2010. Leading by example, he hopes to wean his country - tourism is its biggest economy - away from fossil fuels and towards a mix of wind turbines, solar panels and coconut-burning back-up generators. He is not the first president to gamble on an eco-friendly policy to help promote eco-tourism, but his case may be the direst. If sea levels rise as now predicted - three feet by 2100 - his people will soon have to seriously concentrate on finding a new home (Nasheen's predecessor talked with Australia about moving his people there; Nasheen has suggested he will look into some kind of land-for-fishing-rights swap with India or Pakistan ...).

Fishing

Mohammed Jarrad and his four-man crew left the dock in their slow-chugging dhoni at five this morning. When I meet them unloading the day's catch just as they sun disappears it means they've been at it for fourteen hours, a typical day for a Maldivian fishermen. The haul? About 150 kilos (330 pounds). Not bad, he says, about average. "Though sometimes we have days when we catch 500 kilos ... but those are fewer and fewer."

As he and his team hand the fish up onto the dock from the back of the flat-decked boat they fill plastic crate after plastic crate with dorado, blue and yellow fin tuna, skipjack and one sizable barracuda. By law, every fish caught in Maldivian waters has to be caught by "pole and line." No net fishing, no bottom trawling no seining. Which is a good thing for the health of the fishing grounds, which extend 200 miles off the edges of the Maldives 26 atolls. Yet there are still problems.

Sharks, which used to be prolific here, are largely gone due to over fishing (thanks, as in so many parts of the world, to China's demand for shark fins). Sea cucumber numbers are quickly declining and the government stopped issuing export licenses for fishing for giant clams to prevent serious exhaustion and possible extinction. Tuna and the other popular edibles, while still abundant, have all diminished for a simple reason: Demand. The permanent population of the Maldives has boomed in the past decade, to nearly 400,000. Add to that the 600,000 tourists now coming every year and the pressure mounts.

"Unfortunately we see the pressure on the fish," says marine biologist Anke Hofmeister, citing the lobster haul as example. "Sometimes the fishermen will bring in female lobsters with the eggs scraped off, hoping we won't notice (taking female lobsters is illegal), and often they are smaller than the law permits. But the demand is high from the resorts, so too often some buyers are looking the other way."

As a percentage of the country's business, fishing has slipped as tourism has boomed. In the 1970s fishing provided thirty percent of the nation's revenues; in the 1990s, fifteen percent, in 2000, just six percent. By comparison, tourism now provides over forty percent of the country's GDP.

Watching these tuna fisherman do their job is one of the wildest fishing scenes I've ever seen. A commercial fishing boat here is rudimentary in comparison to much of the rest of the world. Twenty to twenty five feet long, wooden, with a long, flat deck interrupted only by a small, three-sided cabin, which is used mostly for shade during the long, hot days at sea. A long rudder, usually manipulated by the captain's foot, does the steering.

Eight to ten fishermen (always men, never women) bait long poles and cast off the deck simultaneously, and have been known to reel in more than one thousand tuna in an hour. Boats with automated poles can be even more "productive."

Half the catch in the Maldives is for local use, the other half is frozen or canned and exported to Southeast Asia, a $50 million a year enterprise. Mohammed J. and his four-person crew go out six days a week, motoring at least two hours from home each morning. His take this day for the 150 kilos will be about $375, split among five men. On average, each man will earn around $350 a week.

As the setting sun turns the sky purple and orange I ask how often they see green turtles - illegal to catch, but once a mainstay of the local diet here - and he says "every day."

"It is hard to watch them just swim by," he says of the turtles, which can weight up to four hundred pounds. "But we do."

I trust that he's telling me the truth, though he looks away as he is answering. It's hard in these communities for them to change their habits; certainly his father and grandfather and great-grandfather fed their families off green turtles often.

Snorkeling

Swimming along the coral edge of what transplanted marine biologist Anke Hofmeister calls her "home reef" the line dividing the shallows and deep blue is exact. To our left in the brightly sunlit coral, hundreds of shiny reef fish dart and feed; in the dark blue, just to our right, which descends straight down a dramatic hundred foot wall, swim the Maldivian big guys - jackfish, tuna and red snapper, each over one hundred pounds. An occasional spotted eagle ray elegantly flaps its way past in the dark blue below the surface of a calm Indian Ocean.

During a mile-long swim paralleling the beach we spy an incredibly beautiful and vast variety of wrasses, clown, surgeon and parrot fish. A dusky moray eel peeks out of its coral hideaway. A solitary hawksbill turtle flippers past. And a square-headed porcupine fish attempts to hide itself deep inside a rock crevice. As Anke dives to tickle an anemone hugged tight to the coral, a nasty titan triggerfish nips at her; they can be aggressive little buggers and when they bite literally take a chunk of flesh. The shallow, sandy floor running to the beach is heavy with gray-beige coral, colorful clams and even a few handsome sea cucumbers (black with red dots).

The relative health of the coral is somewhat remarkable because recent history here hasn't been particularly kind to it. In 1998, thanks to shifting ocean patterns associated with El Niño, sea temperatures rose above 32 degrees C for more than two weeks badly "bleaching" the coral (the killing of the symbiotic algae that lives within the coral and gives it color). Between seventy and ninety percent of all the reefs surrounding the Maldives 26 atolls are estimated to have died as a result. Slowly they are trying to come back.

While that temperature rise was considered a fluke, today after our swim I ask Anke to guess at the water temps now. "Around 31 degrees C (88 degrees F)," she says, though she not guessing since she's worked and swum here nearly daily for the past four years. "For this time of year, that seems to be normal now. In two more months it will be colder, down to 27, 28 degrees."

In 1998 scientists were astonished that the water temperatures could rise so high, so fast. Now they are worried it may one day become the norm. With approximately 80 per cent of the 1,192 coral islets that make up the island nation just three feet or less above sea level, making it the world's lowest country, the temperature of the ocean is very important. If the temperatures stay high and the coral continues to suffer and die, there goes another barrier protecting these already fragile, at-risk islands.

While warming and rising seas and coral die-offs are everyday concerns throughout the Maldives, as Anke and I walk back down the beach another environmental worry is evident: Many of the beautiful white sand beaches are narrowing, on some islands quite dramatically. It's estimated that fifty percent of the inhabited islands and forty five percent of those with resorts only are suffering from some degree of coastal erosion.

Some of the beach loss is due to man. Continued development demands more sand for cement (though much of the sand used for building in the Maldives today comes from Sri Lanka or India). Increased wave action due to more boat traffic takes a toll. But a major blame is placed on the tsunami of 2004, which sucked massive amounts of sand off the beaches, and it never returned.

When you fly above the Maldives it's easy to see there is no one shape characterizing the outline of the exterior of the atolls or the hundreds of islands sheltered inside them. Strong tides and powerful currents shape each, there is no one pattern thus no single way to reduce or limit the erosion. On different islands different attempts have been made to save the beaches, including building of seawalls or jetties, dredging and pumping. In some cases it is working, in others not.

On one hand it's easy to think of these coral atolls and the islands they protect as tough and impervious, imagining that they've been here a long time and will be here for a longer time to come. But a short swim and a simple walk on a beautiful, hot, hot day quickly reminds just how fragile, how vulnerable they can be.
