In Guadeloupe, coral reefs are experiencing an unprecedented collapse. Between 2022 and 2025, nearly half of the seafloor coverage rate has been lost. The causes: climate warming, multiple forms of pollution, and uncontrolled human activities. The Guadeloupe National Park (le Parc National de la Guadeloupe) is sounding the alarm.
The coral formations of the Guadeloupean archipelago are disappearing before our eyes, putting the entire marine ecosystem in peril. A report by Boris Courret published by the Guadeloupe National Park on YouTube alerts to this dramatic situation. Poor wastewater treatment, in particular, is being singled out as a culprit.
According to Claude Bouchon, professor emeritus at the Université des Antilles and member of the Scientific Council of Guadeloupe National Park, "between 2022 and 2025, we lost approximately 50% of the seafloor coverage rate by corals in Guadeloupe." Today, the rates hover around 5 to 6%, levels deemed "ridiculous," even within the protected areas of the National Park.
