Marine life cemetery: The Caspian Sea ecosystem is collapsing under pressure from global warming and pollution
In late April, the carcasses of endangered seals were once again found on the shores of the Caspian Sea — marking the second mass die-off in just six months. Scientists have yet to agree on what’s driving the deaths: trawl fishing, pollution, disease, or the shallowing of the sea caused by global warming. Since 2020, the Caspian’s water level has been falling by roughly 30 centimeters a year, and the drop is not only disrupting oil transport and threatening navigation.
