The Aral sea sits between Kazakhstan and Uzbekistan, and was once the fourth largest sea in the world. Most people today haven’t even heard of it. What was a 68,000 square kilometer sea, and thriving fishing industry, is now a sea that is 10 % of the original size, too salty and polluted to support fish. In fact the third largest sea in the world, is now considered to be three lakes.
The demise of the Aral Sea was caused primarily by the diversion of the inflowing Amu Dar’ya and Syr Dar’ya rivers in 1960′s to provide irrigation water for local croplands. These diversions dramatically reduced the river inflows, causing the Aral Sea to shrink by more than 50%, to lose two-thirds of its volume, and to greatly increase its salinity. At the current rate of decline, the Aral Sea has the potential to disappear completely by 2020.
