🗞️ Driving the news: The destruction of Ukraine’s Kakhovka dam in June 2023 has unleashed a toxic “time bomb,” exposing over 90,000 tons of heavy metals
• Floodwaters carried industrial pollutants, sewage, and waste into the Dnieper River, contaminating drinking water and farmland
• As the reservoir dries, toxic sediments risk being swept into the water supply, endangering local populations

🔭 The context: The dam explosion submerged towns, disrupted ecosystems, and displaced thousands, with Russia and Ukraine blaming each other for the attack
• Researchers found high concentrations of zinc, copper, arsenic, and oil products, which pose severe health risks
• Heavy metals, previously trapped in the sediment, are now being absorbed by vegetation and moving through the food chain

🌍 Why it matters for the planet: This is considered the most environmentally damaging event of the Ukraine war so far
• Toxic heavy metals can cause brain, liver, and immune system damage, while disrupted ecosystems threaten biodiversity
• If more dams are targeted, the environmental and human toll could be catastrophic

⏭️ What's next: A proposed solution includes constructing two massive barriers to contain the toxic spread, but war prevents action
• The estimated damage cost is nearly $14 billion, yet restoration remains a low priority due to ongoing conflict
• Scientists warn that international law must better protect dams in war zones to prevent further large-scale environmental disasters 

💬 One quote: “The destruction of the dam is the single most environmentally damaging incident of the war in Ukraine so far.” – Doug Weir, Conflict and Environment Observatory

📈 One stat: 90,000+ tons of toxic heavy metals were exposed after the Kakhovka dam collapse
