The ARAL Sea is a shrinking body of water located in Central Asia, between Kazakhstan and Uzbekistan. It was once the fourth largest lake in the world, but due to the diversion of its feeder rivers for irrigation, it has been steadily shrinking since the 1960s. The ARAL Sea is now only 10% of its original size, and the salinity of the water has increased significantly. This has had a devastating effect on the local environment and economy, leading to the loss of fisheries and other industries.
