The issue is not new, but it is still relevant today. This summer again, the bay of Saint-Brieuc saw hundreds of tons of green algae wash up on its beaches. Special Envoy offers a personal approach with a report by journalist Clément Le Goff. He went where he grew up, on his Breton lands, in the bay of Saint-Brieuc, to understand why the problem has been repeating itself every year for 50 years.

The journalist wanted to understand why, since he was very young, the beach close to his parents’ house is invaded by green algae, making swimming impossible. The reporter therefore takes us with him to the town of Hillion, to meet all the protagonists: inhabitants, doctor and… farmers. Farmers who have some responsibility for the formation of green algae. Not easy therefore, to convince them to testify.

“The subject is difficult to deal with, because the farmers, too, live it badly. Especially in this town where they have a view of the sea and the green algae every day. They are well aware that they have a part responsibility “, explains Clément Le Goff. “A responsibility which is also very important according to scientists. But what we want to show is that we cannot say that farmers are the only ones responsible. It is a system that generates green algae. . Everyone has some responsibility. Even the customer. “

These green algae are poisonous and sometimes even fatal when they decompose in the sun after washing up in the sand. In addition to preventing swimming, in addition to giving off an odor that is sometimes unbearable for residents, they make the air breathed unhealthy. “I knew it was dangerous to go into the rotting algae. All Britons know it. However, what I did not know is that even the ambient air, even that bad smell, can be toxic” , reveals Clément Le Goff.

“We took measurements ourselves and we realized that the numbers were important. Several locals came to see us during the filming to complain of headaches, nausea or eye irritation,” continues the journalist at the microphone of Europe 1. “Each time it corresponded to the moment when the algae were present on the beach. And we have no idea of ​​the pathologies that this can generate in the long term.”

The investigation of Clément Le Goff is to be found Thursday evening in Special Envoy, at 9:05 pm on France 2. Two other reports are on the program of the show: Lebanon in bankruptcy and an immersion with the anti-sanitary pass. Elise Lucet’s guest will be Daniel Psenny, the journalist from Le Monde who filmed the Bataclan’s exit from his window on November 13, 2015, and who was injured while going to help victims in the street.
