2 Create a cause-and-effect diagram, which lists a series of effects that resulted from diverting (redirecting) water for irrigation. Effects CAUSE Water for irrigation is diverted from rivers that feed Aral Sea

3 Location:

4 Why is the Aral Sea important? It was once the fourth largest inland body of water on earth It provided rich fishing resources It is an example of Soviet misuse of the environment Fishing once employed many thousands; unemployment is at about 40% today.

5 What started the Aral Sea problem? In the 1950s, the U.S.S.R. wanted to grow cotton in the deserts of Central Asia They needed to irrigate the land by using nearby rivers
