France’s administration is seeking to dismantle dams powering watermills in the name of ecological continuity, a move sparking controversy. This policy aims to restore natural river flows, but faces pushback even within the scientific community. Proponents of preserving the mills argue they represent an important cultural heritage and contribute significantly to local biodiversity. The debate centers on balancing environmental restoration with the preservation of historical structures. Concerns are mounting over the potential loss of these unique sites and the impact on tourism. Advocates are urgently calling for contributions toward repairing and maintaining the mills, highlighting their value beyond their functional purpose. The looming demolitions represent a critical moment for safeguarding this disappearing aspect of French history and ecology.
