The Aral SeaFacts: • As the water quantity decreased, the salinity rose to toxic levels for fish and other wildlife, caused by irrigation and massive amounts of pesticides used in cotton fields (Owen, 2001): • The first drastic increase occurred between 1971 and 1975 when salinity rose to 12-14% (Owen, 2001) • In the late 1980’s the salinity reached 23% (Owen, 2001) Figure 7.
