Question 2
What is the primary reason for the shrinking of the Aral Sea?
◦ There is climatic change in Central Asia.
◦ Large-scale irrigation projects implemented by the Soviets in the 1950s have diverted water from the two rivers that feed the sea.
◦ Tectonic rifting in the region is causing the sea's water to be removed beneath the ground surface.
◦ Much of the water has been removed directly from the sea surface by the numerous nuclear desalinization plants along the Aral's shore.
◦ The Chinese purchase of the Aral Sea as an aquifer has led to a dramatic drop in its water level.
