In A Dying Sea: The Disaster of the Sea of Marmara, filmmaker Florian Seltmann examines one of the most alarming ecological crises in recent history. In 2021, the Sea of Marmara faced an unprecedented spread of mucilage—a dense, slimy organic substance—triggered by untreated wastewater, agricultural runoff, and rising sea temperatures. This phenomenon suffocated marine life and ecosystems, threatening the region’s biodiversity.
Collaborating with the Marine Life Conservation Society, Florian documents efforts to address the disaster, from beach clean-ups to dives uncovering ghost nets, algae-smothered coral reefs, and oxygen-deprived death zones that signal ecological collapse. The film expands its focus to draw stark parallels with global environmental degradation, urging reflection on humanity’s impact on the planet.
Through striking visuals and a deeply personal narrative, Florian Seltmann delivers a powerful call to action, challenging viewers to protect our oceans and prevent the catastrophic loss of life they sustain.
