"The Black Sea ecosystem is on the verge of collapse. Constant deadly military activity – mine explosions, bombing, missile launches and the use of powerful sonar systems, as well as enormous volumes of chemical pollutants, including the consequences of the Kakhovka disaster – is systematically destroying the sea's unique biodiversity," the park's scientists said.
