Draining two million cubic meters of water to protect a small animal in danger of extinction. This has been the task of those who have worked to remove the Enobieta reservoir and ensure a safe haven for the Pyrenean desman. This amazing story took place in Artikutza, the estate that San Sebastián bought in Navarre a century ago and which is now one of the best-preserved natural sites on the Cantabrian coast. In Normandy, meanwhile, the large Vezins dam has been removed. Its demolition will allow salmon to return to the Sélune River. Abandoned dams on rivers are barriers to biodiversity, and their demolition allows us to imagine a more habitable planet. That future will depend on small gestures, or large ones, such as those in Vezins and Enobia.
