Dead fish lie on the shores of Koroneia Lake in northern Greece, on Thursday, Sept. 19, 2019. Tens of thousands of dead fish are washing up as the water level has plummeted to less than a meter deep (three feet) and the lack of oxygen in the water is leading to mass mortality of everything in it.

Some experts have questioned whether there’s enough plankton in the lake to sustain the invasive carp away from shoreline areas.
