Ecological crises have been reported in Greek lagoons, characterized by mass mortality events and severe pollution. In the Kalogria Lagoon, thousands of dead fish washed ashore, a phenomenon experts suggest may be linked to anoxia, or the sudden depletion of dissolved oxygen. Potential contributing factors include eutrophication from fertilizer runoff, high water temperatures, declining water levels, or the blockage of natural channels connecting the lagoon to the sea.

In the Missolonghi Lagoon, specifically the Aitoliko area, local fishermen report a crisis driven by industrial waste, urban sewage, and agricultural pesticides. This contamination has caused intense odors and mud layers on the water surface, threatening local fauna and the fishing industry. Reports indicate that a 21.4 million euro protection budget approved in 2015 went unutilized, while the subsidence of historical bridges has further obstructed water circulation and exacerbated pollution levels.
