The Aral Sea will disappear from the map

As recently as the 1970s, the Aral Sea was the world's fourth largest lake, with an area of 68,000 km2.However, Soviet irrigation projects diverted the Amu Darya and Syr Darya rivers which fed into it. By 2004, the sea had shrunk to 25% of its original surface area, and a nearly fivefold increase in salinity had killed most of its natural flora and fauna. By 2007, it had declined to 10% of its original size.Although a dam project in 2005 saved what little remained of the northern part of the sea (the Small Aral), the much larger southern part of the sea (the Large Aral) continued to shrink, and by 2019 is expected to have evaporated entirely.
