Mediterranean Sea: Urgent Alert From Biologist Laurent Ballesta

Montpellier, France – Marine biologist and underwater photographer Laurent Ballesta is calling for sweeping changes to how the Mediterranean Sea is managed, warning that unchecked human activity is pushing the ecosystem to the brink. Ballesta’s assessment comes ahead of a fundraising gala hosted by the Montpellier Handball club on May 19, 2026, to support his research into Mediterranean biodiversity.

Ballesta, who has spent over three decades diving in the Mediterranean, describes a sea under immense pressure from record levels of tourism, fishing and unregulated navigation. “It cannot be a space of freedom when Notice hundreds of thousands of users,” he stated, emphasizing the lack of enforceable regulations that govern activities within the sea, unlike those on land. He points to areas where as many as 300 anchors are dropped daily, destroying seagrass beds and damaging critical habitats.

While marine protected areas exist, Ballesta argues their effectiveness is severely limited. “In 99% of cases, you can do almost anything you aim for,” he said, characterizing current protections as largely theoretical. He advocates for the creation of genuine sanctuaries, strict regulation of all maritime activity – including speed, mooring, and fishing – and a fundamental shift in how the Mediterranean is viewed and managed.

Ballesta’s concerns are underscored by his own observations. He notes that in areas around Occitanie, ecosystems have already undergone significant changes, with species becoming increasingly rare and landscapes transforming. His photographs, he says, are increasingly serving as documentation of a disappearing world.

However, Ballesta also highlights glimmers of hope. He points to areas where strict protection measures are in place, where marine life has demonstrated a remarkable capacity for recovery. These areas, however, currently represent a mere 0.1% of the Mediterranean Sea, a figure he deems insufficient to address the scale of the crisis.

Ballesta is also reassessing his approach to raising awareness. He previously believed that showcasing the beauty of the Mediterranean would inspire conservation efforts, but now argues that such imagery often fuels further exploitation. “When you demonstrate something beautiful, you create desire,” he explained. He now focuses on revealing the mystery and complexity of the underwater world, hoping to foster a deeper sense of respect and understanding.

His latest project, “Loin du ciel” (Far From the Sky), developed with Pierre Descamp, embodies this shift. The project, encompassing a book and exhibition, features images from diverse locations – including Antarctica and Polynesia – but shares a common thread: the exploration of the unknown. A second volume of “Loin du ciel” is already planned.

A recent discovery by Ballesta’s team, off the coast of Corsica, offers a compelling example of the Mediterranean’s hidden richness: nearly 18 million nests of picarels spread across over 700 hectares, a phenomenon described as unique globally. The Montpellier Handball gala aims to support further research into such biodiversity hotspots.

Ballesta dismisses the debate over optimism versus pessimism, stating that action is what truly matters. He urges individuals to make conscious consumption choices, engage in advocacy, and participate in the political process. He emphasizes that inaction is not an option, and that the future of the Mediterranean hinges on concrete steps taken now.
