To combat the proliferation of green algae in Brittany

The massive proliferation of green algae has affected many sites on the coasts of Britanny since the seventies. These stranding of green algae, also called “green tides”, have important consequences in terms of health, costs and image for the concerned areas and for Brittany. It is worth recalling the accidental deaths of joggers in Saint-Michel-en-Grève in 1989, then in Hillion in 2016, of dogs on a beach of Hillion in 2008, of an employee in charge of transporting green algae to Binic in 2009 and of a horse in Saint-Michel-en-Grève the same year, followed by the hospitalization of its rider.
