What major changes have occurred in the arak sea between 2000 and 2012

Between 2000 and 2012, the Aral Sea has experienced less water income, increased salinity, significant loss of water, the formation of separate parts, and huge loss of biodiversity.

Explanation:

The Aral Sea, once one of the largest in the world, has experienced a tragic story since 2000. Once a great and vibrant lake, it came on the verge of drying out and dissapearing from the map. The reasons for this have been the smaller water income, loss of water, increased salinity, formation of smaller separated lakes, and loss of biodiversity.

Because of agriculture, namely, cotton farming, the water supply to the lake has been significantly lowered, leading to larger evaporation than water income. The lake started to lose its water rapidly, and by becoming shallower its temperature rose, so the evaporation became even larger, the salinity increased, and from one large lake, few smaller ones have formed because a large portion of it dried out. Because of all of the aforementioned things the biodiversity suffered badly.
