Once the fourth-largest inland body of water in the world, Asia's Aral Sea has been steadily shrinking for the last 50 years as irrigation projects have drained off the river water feeding into it. The shrinking water supply has split the sea into two sections: the Small Aral Sea to the north in Kazakhstan and the Large Aral Sea to the south, shared by Kazakhstan and Uzbekistan. The Small Aral Sea, also called the North Aral Sea, morphed into a heart shape, as seen in this satellite image taken on July 24, 2010.
