Clip – The Aral Sea Questions 1. Why is the Aral Sea drying up? 2. How is the shrinking of the Aral Sea affecting the people who live nearby?

Background The Soviet Union did not have enough food or industries for its population. How would you use farms to fix both?

Collective Farms The Soviet Union created collective farms to increase food production and clothing production. –Food production  grow wheat –Clothing production  grow cotton

Cause - Irrigation Program The Aral Sea The government started diverting water from the Amu Dayra and Syr Dayra Rivers to irrigate wheat and cotton fields.

Effects - #1 Desertification The rivers dried up so the Aral Sea began to shrink. Land that used to be underwater turned to desert. This left behind massive salt residue and caused desertification.

Directions: In your notebook, complete the Frayer Model below. DESERTIFICATION 2. Definition  spread of the desert. 3. How does desertification affect the people living near the Aral Sea? 4. Sketch

Effects #2 – Health Effects Wind blows the salt mixed with chemicals creating many health problems.

Effect #2 – Health Effects Answer the questions below using the article. 1.How has the shrinking Aral Sea caused health problems? 2.What are the health problems? 3.What are the effects of the increase in the salt content of the Aral Sea?
