Ch 15 section 3

The Shrinkng Aral Sea
a) between 1960and the present, the aril sea lost about 80 percent of its water.

A disappearing lake
a) the aril sea receives its water from the amu darya and the syr darya rivers
b) it loses most of its water by irrigating cotton fields.

Effects of agriculture
a) Agriculture practice is a problem because cotton growers use pesticides
b) runoff= rain fall not absorbed by the soil that runs into the stream and rivers.
c) of the 24 species of fish once found in the seas none are left now
d) retreating water led to pesticides and salt being free and then picked up by windstorms which harm  near by populations

saving the aril
a) to save the lake you would have to remove 9 out of the 18 million acres surrounding it.

The Russian Winter
Coping in siberia
a) more than 32 million people make there home in Siberia
b) temparatures have ranged from minus 90 to 94 in summer--- a span of 184 degrees
c) After the winter almost huge clouds of bugs come into the summer and attack the civilians
d) another problem is that the grounds start to unfreeze and sink taking any building or structures with them.
Crosssing the wild west
a) trans siberian railroad, used to make transport safer and easier for travel in siberia and wild west.

An enormous project
a) built a railroad that crosses 5,700 miles of land
b) had to clear almst 100,000 acres of forest to make the project

resource wealth in siberia
a) used the railroad to increase population and get more resources
b) by 1914 there was almost five million settler/farmers who lived in siberia.
c) made a lot of profit from discovered coal and iron ore deposits.

summary
despite the aril sea depleting slowly due to cotton fields the people are still living there using what ever resources they can. Siberia how ever seems to be growing quite nicely with the creation of an extensive rail system. Now siberia has a great economy despite the wealth being a set back.

water was being taken for irrigating the cotton fields
3) What other environmental problems affect the area?
