Due to many factors like climate change, the ever growing need for clean water, and changes in waterways, the size of bodies of water across the world have experienced changes. Ocean levels have risen, but some lakes and seas have experienced a decrease in size. One in particular is the Aral sea. The Aral sea is a major water source for Uzbekistan, but has experienced a massive decrease in total water content. The cause of this is the diversion of waterways upstream in Kazakhstan and Russia.
