Horse dies, France faces reality of toxic beaches

(AP) -- It should have been a perfect day for Vincent Petit, finishing up an afternoon gallop on a wide expanse of beach along a pastel-colored bay. Instead, he and his mount were sucked into a hole of noxious black sludge.

The horse died within seconds, the rider lost consciousness and a dirty secret on the Brittany coast reverberated across France - decaying green was fouling some of its best beaches.

A report ordered by the government after the accident found concentrations of gas emitted by the rotting algae were as high as 1,000 parts per million on the beach where the horse died - an amount that "can be fatal in several minutes."

There had been signs of a crisis for years in this idyllic corner of Brittany. But scaring away tourists was in no one's interest, including the farming industry - the region's economic backbone - whose nitrate-packed fertilizers power .

So, while tongues wagged, folks whispered and acrimony grew, an official hush prevailed. It took the death of the horse to bring the problem into the open.

Decaying ulva algae threatens other beaches around France and the world, from the United States to China, experts say. Last year, the Chinese government brought in the army to remove the slimy growths so the Olympic sailing competition could be held.

In Brittany's Cote d'Armor region, conditions are perfect for its spread - sunlight, shallow waters and flat beaches. Chemical and natural fertilizers like pig excrement, loaded with nitrates and phosphorous, have saturated the land, spilling into rivers and the ocean, feeding the algae that then proliferate.

Harmless while in water, the algae form dangerous gases - notably hydrogen sulfide, with its characteristic rotten-egg smell - when they wash up on land and decay. A white crust forms and traps the gases, which are released when stepped on or otherwise disturbed. Over time, putrefied algae turns sand into a black silt muck, sometimes containing pockets of poison gas.

On July 28, Petit, a 28-year-old researcher in a state-run virology lab, had just finished riding his thoroughbred Sir Glitter, a retired racehorse, on the Saint-Michel-en-Greves beach, when the two were suddenly mired in muck as he led the horse on foot in search of a place to cross a stream running through the sand.

"The horse and I slid in," said Petit, who is also trained in veterinary studies. "A horse in that situation is in an enormous panic, but he didn't have time to struggle."

Petit said he watched horrified as his horse stopped breathing and died within about 30 seconds, then he himself passed out. Petit was pulled from the mire by a bulldozer shovel after a man who witnessed the accident gave the alert.

While locals are aware of the perils posed by the silt traps that lurk under the sand around streams that feed from the beach into the ocean, Petit did not sense the danger until the ground gave way and he and his horse were sucked into the noxious ooze up to the man's chest.

Police initially ruled the horse suffocated, but an autopsy showed the animal died of an acute pulmonary edema with symptoms "compatible with gaseous intoxication in a brutal manner," Petit said, quoting the report, which he paid for.

There was no foreign matter in the horse's throat, lungs or stomach and no sign of a heart attack, he said.

There have been local efforts to clear the blight. Mayor Rene Ropartz said Saint-Michel-en-Greve, a village of 480 people, collected 10,000 tons of algae from the mile-long beach by the end of July; several years ago they cleaned up 21,000 tons.

"This bay is magnificent and, unfortunately, this tarnishes the image," said Ropartz, adding that the horse's death shows the role of the algae "is no longer in doubt" and spurred the government into action.

Prime Minister Francois Fillon visited Saint-Michel-en-Greve last week, pledging measures to control the algae by next spring.

The horse is only the latest victim of the algae's noxious fumes. A man was found dead on the same beach two decades ago, his arm sticking out from a pile of algae. Another man fell into a four-day coma after cleaning algae 10 years later. And last year, two dogs died while romping on an algae-covered beach 60 miles to the east.

At Grandville beach, where the dogs died, putrefying algae has turned the sand to blackened silt, spotted with green swampland and white crusty clumps of algae in decay. The stench of hydrogen sulfide hangs heavy in the area, where people occasionally show up to gawk at the ruined beach.

"Once you could swim here. Now, it's no longer a beach, it's a garbage dump," said Andre Ollivro, a founder of Halt the Green Tide, one of several ecology groups that has warned of the algae peril as bad blood built with farmers.

After the dogs died, scientists at CEVA, a state-run institute that tracks algae in France, began protecting themselves with hand-held instruments to measure hydrogen sulfide, said agency official Sylvain Ballu.

Ballu said he found 500 parts per million of hydrogen sulfide in the area where the dogs died.

Solving the problem will take far more than cleaning algae from beaches.

Water in the affected region currently measures 32-33 milligrams per liter of - compared to a normal level of 5 milligrams, said Alain Menesguen, a biologist with the French Institute for Exploitation of the Sea. Some rivers reach 60-70 milligrams and the ground water in some areas reaches 100 milligrams, he said.

"We've reached saturation," he said. Returning to normal levels will require huge changes in the agricultural sector without seeing any immediate drop in the algae mass.

"This is very difficult for farmers and politicians to accept," Menesguen said.

Solange Le Guen, who raises 80 cows on a farm planted with corn, wheat and other crops in the hills behind Saint-Michel-en-Greve, says farmers aren't the only ones to blame.

Fault also lies with water purification plants located too close to the ocean, she said. She conceded, when pressed, that "people have abused" fertilizers. "We were badly advised," she said.

For Petit, it comes down to assuring some good comes from the tragedy and his scrape with death.

"I'm trying to do everything so that my horse didn't die for nothing, that this won't just end as a simple accident," he said. "It could have been worse, for me."

This, folks, is what we really should be concerned about--far more than about CO2 in the atmosphere. It's stuff like this that really kills people.

What a shameful way to have to recognise that something should be done about this here and abroad.

That's horrible. And it's all part of the same problem-the lack of responsibility. It's not Nature that we protect by being responsible, it's us-our life, our comfort.

The fact that this made the news might have something to do with a change in French attitudes. Apparently efforts to clean up the Seine River have such positive results that fish varieties which haven't been seen there for decades are reappearing.

Where there's a little bit of hope for a positive outcome, people are more likely to be receptive.

Please explain why you think this potential disaster, which clearly needs to be addressed, means we can ignore other similar potential disasters? I think this problem and global warming threats and several other problems all need proper propotionate attention.

Len,

You have already made it abundantly clear that you do not understand the science well enough. You just proved it again. Otherwise, you never would have asked the question you have.

Here it is, in layman's terms.

This problem kills NOW and is clearly a present danger.

CO2 is not a danger until it reaches levels higher than 5000 ppm in an enclosed space and there have been to date no predictions of either the IPCC or the NSIDC that have held true in all particulars.

In short, the evidence is that such dangers as the above need addressing now and that the jury still is out for CO2 so long as pseudoscientific fearmongering continues in the face of the growing evidence that the AGW hypothesis is a crock full of crap.
