Geography H/W – The Disappearing Aral Sea This essay intends to first introduce the disappearing Aral Sea, which due to the extensive agricultural activities devised by the Soviet government in the region, the former fourth-largest lake of the world is now the world's eighth largest lake. This has resulted in perhaps the world's most prominent man-made ecological disaster, giving its location and background knowledge with a map, and then describe its future in terms of how it is going to be utilized and what the consequences are, and then finally state what can be done about this “crisis”. @. The Aral Sea is located in the Central Asian Republics of Uzbekistan and Kazakhstan. Due to its location in the center of a vast mainland…show more content…
