Introduction
The reason that we chose to do this as our project is because the shrinking of the Aral Sea has been so shocking and it is a prime example of the negative effects that humans can have on the environment. According to UN Secretary General Ban Ki-Moon, the Aral Sea crisis is "one of the planet's worst environmental disasters" (14).

Maps
The Aral Sea is a regional ecosystem, located in present day
Kazakhstan and Uzbekistan, formerly countries of the Soviet Union. Although the
Aral Sea is located only in Kazakhstan and Uzbekistan, the Aral basin is shared
by three additional countries: Kyrgyzstan, Turkmenistan, and Tajikistan (1, 4).
Once one large lake, it has since split into four smaller lakes: the North Aral
Sea (Little Aral), the west and east portions of the South Aral Sea (Big Aral),
and a small lake in between the North and South Seas.

Historical State
The Aral Sea was once
the fourth largest inland lake in the world, measuring 66,100 km2 in
1963 (1, 6). Before this time, it was
home to about twenty species of native fish and fishing was a predominant
industry, providing thousands of people with employment (8, 10). There were
over 70 different species of mammals and 319 species of birds that lived in the
deltas of the Amu Darya and Syr Darya rivers (8). There were also vast expanses
of tugay vegetation around the Aral Sea, over 100,000 hectares, where many of
these species of birds and mammals made their habitats (8). There was also just
the right amount salinity in the lake to support sufficient communities of zooplankton
and plant communities (10).
