“I used to be the second most stunning child within the native hospital in 1945.” Through the years, André Ollivro, 77, has learnt easy methods to placed on a present for journalists. He opens with a private story, strains up the anecdotes of his life, with a scrapbook full of stories clips he’s featured in as a prop, and readily poses for the digital camera. Wearing darkish blue overalls, a blue and white striped T-shirt, and a purple cap, he appears just like the epitome of a Breton man one may see on the duvet of an area vacationer information.
Ollivro has turn out to be considerably of an area legend regardless of himself, by advantage of combating the air pollution on his doorstep. He spends his summers in a white-painted bungalow above the seashore of La Grandville, in Brittany (France), which has been lined by a mass of inexperienced algae each summer time for many years.

Half 2: Water air pollution and algal blooms: the collateral injury of the inexperienced revolution
Half 3: Who will cease Brittany’s poisonous inexperienced tide?
The inexperienced algae is a sea lettuce native to the area that will get washed ashore amid tide modifications and waves. However for the reason that Nineteen Seventies, the presence of the piles of decomposing algae, smelling of rotten eggs, on the seashores has turn out to be a scourge for the area, and – based on Ollivro, different activists, and scientists – constitutes a severe public well being concern.
When the seaweed begins decaying, it emits hydrogen sulphide, a fuel that may, relying on the focus and period of publicity, set off complications or eye irritation, provoke unconsciousness, and even trigger loss of life. Through the years, quite a few animal deaths – wild hogs, canine, and a horse – have been linked to the toxic fuel emanating from the seaweed. Furthermore, six human deaths have been linked to the presence of algae, though the causal hyperlink nonetheless hasn’t been absolutely established because of the lack of checks carried out.
Area feeding France
Right now, the blooming of algae in Brittany is linked to an elevated enter of nitrates from fertilisers and manure getting into the small waterways working by way of dense agricultural areas, flowing to the ocean. The difficulty of the extreme enter of nitrates has been a long-standing concern. In 2001, the European Courtroom of Justice condemned France for breaching the Nitrates Directive concerning the degrees of nitrates in some river basins in Britanny; in 2004, the nation was condemned for not designating sure areas as Nitrate Weak Zones; and in 2014, France was condemned as soon as once more for breaching the Directive.
The inexperienced tides often happen in shallow bays, the place the gradual renewal of the coastal water leads to the retention of vitamins. The tides are extra intense in intervals of larger daylight, between mid-Might and September.
After World Warfare II, Brittany remodeled from a area of small farming plots to a frontrunner in livestock farming in France, feeding “one out of three French residents.” Greater than 60 % of the regional territory is used for agriculture, and the area is the chief in egg and pork manufacturing within the nation. Additionally it is one of many main areas for vegetable manufacturing within the nation.

In his e book Inexperienced Tides: 40 keys to understanding, scientist Alain Ménesguen explains how the presence of algae in Brittany intensified after World Warfare II, together with the event of high-intensity agriculture. In 1971, air pollution by inexperienced algae was talked about for the primary time in an official capability, within the municipal council of Saint-Michel-en-Grève. In that yr, over the course of ten days in June, 6,600 cubic metres of algae have been amassed. Within the interval 1997–2018, the quantity of algae amassed yearly didn’t drop beneath 25,000 cubic metres.
“After I retired and got here again to Brittany, it wasn’t the identical surroundings that I may bear in mind from my childhood. Agriculture had advanced and altered the panorama within the course of,” he says. He quickly grew to become the president of the organisation Halte aux Marées Vertes (Cease the Inexperienced Tides), which has fought air pollution from inexperienced algae ever since. The organisation has filed lawsuits in opposition to the French state for not defending its residents, and organised mass protests to cease the enlargement of mass farms and the constructing of biogas crops operated utilizing animal manure.
When the algae season begins, Ollivro, a former fuel technician, can typically be seen along with his fuel masks and a hydrogen sulphide monitor on the seashore, measuring the fuel ranges.
On July 21 2022, his machine begins beeping as quickly as Ollivro steps into what appears like a pile of brown mud however is, in reality, decomposing algae. The beeps point out the presence of hydrogen sulphide. The degrees hover round 40–50 elements per million (ppm), which, based on a chart that Ollivro is carrying with him, can produce a “noticeable odour” and “palpable irritation of the eyes.” Complications and nausea begin at 160 ppm. At ranges above 2400 ppm, the fuel might be lethal, relying on the period of time spent inhaling it.
The mere presence of algae provokes a disbalance in natural world. Animals flee seas overburdened with algae due to the resultant oxygen depletion, whereas the degradation of algae on the seashore leads to a decimation of the variety of animals, largely invertebrates, residing in shore waters. Nevertheless, in July 2008, the pockets of hydrogen sulphide from the decomposing algae have been linked to the deaths of two canine.
A yr later, a horse was discovered lifeless on one algae-polluted seashore. In July 2011, at the least 31 wild boars have been discovered lifeless on a muddy, algae-covered seashore. The deaths of two joggers, one in 1989 and one other in 2016, a diver engaged on algae pickup getting into a coma in 2018, and the loss of life of one other are all considered linked to the hydrogen sulphide.
Agricultural omerta
In her e book Inexperienced Algae: The Untold Story, French journalist Inès Leraud traces algae air pollution and the problems surrounding it throughout a long time. Leraud notes that Joel Kopp, a scientist from the French Institute ISTPM (now IFREMER, French Analysis Institute for the exploitation of the ocean) concluded in 1977 that coastal air pollution is brought on by agriculture. In parallel, Leraud explains how the agricultural foyer has tried to silence the scientists and activists, and has lobbied the native authorities so as to have the ability to proceed enterprise as standard. And generally, a few of them have resorted to threats.
In entrance of his bungalow, Ollivro lays down images and paperwork outlining his wrestle in opposition to inexperienced algae air pollution over the previous 20 years and the problems this wrestle has introduced him. There have been menacing emails, insults directed in direction of him on the road, a pile of manure dropped in entrance of his home, a firecracker that destroyed his letter field, a lifeless fox left in entrance of his door.
The agricultural neighborhood has lengthy disputed the connection between extreme nitrates and algal bloom. In 2011, when the seashore of Morieux was closed after the loss of life of 36 wild boars, the FNSEA, a French umbrella organisation charged with the illustration of native and regional agricultural unions, organised a soccer recreation on the seashore to point out that there was nothing to concern. Right now, they don’t contribute to the price of cleansing up the algae on the seashores, they usually fought taxation of nitrate exceedances on the premise of the polluter pays precept within the invoice on water of 2002, as Alain Ménesguen recollects in his e book.
Accountability of the state
By now, the hyperlink between extreme nitrates and algal bloom has been confirmed by quite a few scientists, environmental organisations and court docket choices. Nevertheless, Brittany’s water company did not admit this till the top of the Nineteen Nineties, whereas the federal government waited till 2010.
The tide has turned since 2010. Right now, the native authorities measure the degrees of fuel on the seashores, and shut them to the general public in instances of large algae presence. Additionally they have an obligation to choose up algae deposits on the seashores, and retailer them in disposal centres, the place they’re dried. The State and the native authorities spend about €1 million per yr cleansing up the algae.
The French authorities has additionally handed two motion plans for combating inexperienced algae, in 2010, and 2016. In 2021, the French Courtroom of Auditors objected that each plans had “ill-defined targets and unsure results on water high quality,” a scarcity of enough funding for the measures, and a scarcity of consistency with different agricultural and agri-food insurance policies.
“The issue with these motion plans is that they don’t goal to scale back the inputs, however solely the nitrate leakage. Furthermore, they’re largely focusing on animal manure, and disregarding the inputs from mineral fertilisers,” explains Estelle Le Guern, lead of the analysis unit on water and agriculture with Eau and Rivières (Water and Rivers), an NGO that has been engaged on the safety of regional waterways for the reason that Nineteen Sixties. “Once we take a look at the info, we see that the air pollution by nitrates has progressed, so there’s a discrepancy between the legislation and the scenario within the subject. The legislation is healing, so it doesn’t stop air pollution,” she provides.
‘You possibly can’t battle the inexperienced tides with out questioning the agricultural system. And doing which means to interact in politics.’
Annie Le Guilloux, Halte aux marées vertes
In 2022, Eau and Rivières filed two lawsuits in opposition to the French state within the Rennes administrative court docket. The NGO estimated that the state didn’t act adequately to curb the air pollution, and estimated the damages – attributable to seashore closures and cleansing actions – to be €3.2 million. This occurred because the third Inexperienced Algae Preventing Plan was introduced. The NGO denounced it as “not concrete sufficient” and deplored the shortage of “enough funds.”
Environmental organisations additionally proceed the battle – otherwise. Right now, the NGO Halte aux Marées Vertes (“Cease the Inexperienced Tides”) has a brand new co-president, Annie Le Guilloux, who continues the battle that Ollivro began. Le Guilloux, born and raised within the area of Saint Brieuc, the area with probably the most acute algae air pollution, explains that present measures promoted by the federal government aren’t sufficient, and are complicated for the farmers themselves. “There are tables defining what the width of a buffer zone subsequent to a waterways must be, relying on the slope of the agricultural slot and its size. That is an instance of how we hold including an increasing number of difficult measures that produce solely beauty modifications,” she says.
Right now, regardless of us residing within the age of omnipresent info, she believes that individuals are nonetheless not conscious of the amplitude of the issue.
“You possibly can’t battle the inexperienced tides with out questioning the agricultural system. And doing which means to interact in politics – even if you happen to’re not belonging to a sure social gathering or political motion,” she says. Right now, they be part of forces with different environmental organisations, akin to Extinction Riot. In the summertime of 2022, they began a joint marketing campaign to lift public consciousness amongst beachgoers of the problems surrounding inexperienced algae.
Le Gouilloux believes that younger blood is required, as many really feel defeated after years of wrestle. “We, who’ve been combating for a very long time, must work with youthful teams akin to Extinction Riot. I’ve expertise, however I’m not in a position to climb the constructing of an area authorities to place up a banner, which is what they did in one of many final protests. And we want extra spectacular actions like that if we wish to curiosity youthful generations on this concern,” Le Guilloux concludes.
