Once the world’s fourth-largest lake, the Aral Sea lies between Kazakhstan and Uzbekistan and has dramatically shrunk since the 1960s due to Soviet-era irrigation projects diverting its feeder rivers. This has led to an environmental disaster, impacting the fishing industry and public health. While the eastern basin is now the Aralkum Desert, efforts to replenish the North Aral Sea through dam construction have seen some success, with rising water levels and returning fish populations. Recognized by UNESCO for its historical significance, the Aral Sea serves as a stark reminder of the consequences of unsustainable water management.Wikipedia
