In late April, NASA’s Aqua satellite captured Lake Urmia with a deep green hue. Now the lake, once one of the largest in the Middle East, looks more like a gigantic crime scene. Like the famous Aral Sea between Kazakhstan and Uzbekistan and the Salton Sea in California, the salty expanse of Lake Urmia in Iran has been drying up and shrinking for decades. The waters of Lake Urmia changed from green on April 23 to red on July 18, as seen by a NASA satellite.
