How Conflict Has Affected the Black Sea's Environment
According to Viktor Demchenko, deputy director of the Institute of Marine Biology at the National Academy of Sciences of Ukraine, the Black Sea's ecological health has improved since the start of the full-scale invasion. He notes that signs of recovery emerged as early as the first year of the war. This turnaround is largely due to a sharp drop in human pressure on the ecosystem, with the number of vacationers falling several times below pre-war levels. However, military operations continue to cause localized environmental damage, including explosions and spills of oil and fuel.
Why the Black Sea Is Becoming Cleaner
Demchenko explains that in peacetime, the sea was polluted by nutrients like phosphorus and nitrogen compounds from wastewater treatment plants, farmland, and illegal industrial discharges. These nutrients triggered algal blooms that turned the water green. But during the war, many resort areas have been closed, and numerous factories have either shut down or reduced operations. As a result, far fewer nutrients are flowing into the rivers and the Black Sea itself.
“The number of vacationers has dropped dramatically. Nature is getting a break from people and starting to recover. We observed that the Black Sea's ecological indicators began improving in the very first year of the war,”

At the same time, he cautions that military activities and emergencies in the region can create local environmental problems. “We hope these issues won't lead to long-lasting negative changes. Overall, by watching how the war affects Black Sea ecosystems, we see how resilient these waters can be,” he added.
During the full-scale war, the Black Sea has also seen bird deaths from oil product leaks originating from Russian sources, killing hundreds of thousands of birds. These incidents highlight the complex environmental situation in the region, where even as overall conditions improve, local crises demand urgent action.
The state of the Black Sea illustrates the contradictory environmental effects of the war in Ukraine. While reduced human activity has boosted broad ecological indicators, ongoing military operations create new threats. Future restoration and conservation efforts must take both factors into account to ensure the long-term stability of the Black Sea ecosystem.
As the Black Sea ecosystem shows signs of recovery due to reduced human activity, experts emphasize the importance of understanding the broader implications of these changes.
