HUMAN ENVIRONMENT INTERACTION

Chapter 21, Section 3


Human environment interaction

Because of scarce water supplies, people in Southwest Asia

use several methods to obtain fresh water for

drinking and

for

agriculture.


Dams and pipelines

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.


Israel

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?


Desalinization

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

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 25-30 YEARS.

DRIP IRRIGATION THAT CONSERVES

WATER AND DRIPS IT AT THE ROOTS

OF PLANTS IS THE MOST EFFECTIVE

METHOD IN DRY CLIMATES.

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 ?


Human environment interaction

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.
