1. HUMAN ENVIRONMENT INTERACTION
Chapter 21, Section 3

2. Because of scarce water supplies, people in Southwest Asia
use several methods to obtain fresh water for
drinking and
for
agriculture.

3. DAMS AND PIPELINES
TURKEY IS BUILDING A SERIES OF DAMS ON THE EUPHRATES RIVER
Why would building a dam on this river be controversial? Look at the map on page 494.
Countries downstream
from the dam
may lose access to enough
water
for their citizens’ needs.

4. ISRAEL THE NATIONAL CARRIER PROJECT IN ISRAEL WILL CARRY WATER
FROM THE MOUNTAINS, SEA OF GALILEE,
AND THE JORDAN RIVER.
LOOK AT YOUR MAP OF ISRAEL.
WHAT POLITICAL PROBLEMS WILL ISRAEL HAVE WHILE
CONSTRUCTING AND USING THIS PIPELINE?

5. DESALINIZATION SOME COUNTRIES HAVE DESALINIZATION PLANTS
TO REMOVE SALT FROM SEAWATER
THIS PLANT IN SAUDI ARABIA IS VERY
EXPENSIVE TO BUILD AND OPERATE.
WHERE DOES SAUDI ARABIA GET THE MONEY
TO BUILD A PLANT LIKE THIS?
DESALINATION IS ALSO DONE
ON CRUISE SHIPS

6. IRRIGATION FOSSIL WATER FROM AQUIFERS WILL
NOT BE REPLACED, DUE TO THE LACK
OF ADEQUATE RAINFALL.
EXPERTS ESTIMATE THAT AT THE
CURRENT RATE OF DEPLETION, THE
AQUIFERS IN THIS REGION MAY
DRY UP IN YEARS.
DRIP IRRIGATION THAT CONSERVES
WATER AND DRIPS IT AT THE ROOTS
OF PLANTS IS THE MOST EFFECTIVE
METHOD IN DRY CLIMATES.

7. OIL FROM SAND OIL WAS DISCOVERED IN PERSIA, NOW KNOWN AS IRAN, IN 1908
HOW WOULD THE DISCOVERY OF OIL CHANGE THE CULTURE OF A COUNTRY?
AFTER WORLD WAR II, ONE OF THE LARGEST OIL FIELDS WAS DISCOVERED IN SAUDI ARABIA
READ PAGE 497, “FORMING PETROLEUM.”
WHY DOES THE OIL EXIST IN SUCH LARGE QUANTITIES HERE ?

8. LOOK AT THE DIAGRAM ON PAGE 498
LOOK AT THE DIAGRAM ON PAGE 498. DRAW A FLOW MAP TO SHOW WHERE THE PATH OF REFINING FROM CRUDE OIL TO GASOLINE. WRITE 3 RISKS OF TRANSPORTING OIL THROUGH PIPES, SHIPS, OR TRUCKS.
