Title: Describe the causes and effects of air pollution and flooding in India and China.


1
Pollution in Asia
  • Describe the causes and effects of air pollution
    and flooding in India and China.
  • Describe the causes and effects of pollution on
    the Yangtze and Ganges Rivers.

2
Air Pollution
  • Asian Brown Cloud
  • 2 mile deep brown haze
  • Respiratory problems
  • Climatic Changes
  • Floods
  • Acid rain
  • Blocks Sunlight
  • Destroys crops
  • Causes
  • Industrialization
  • High population in Urban areas
  • Burning wood and other biomass material
  • Many areas lack electricity or other cleaner
    energy sources

Air Pollution
  • Chinas is the worlds fastest growing
    economieswith no environmental regulation
  • India has some 500,000 annual deaths from indoor
    air pollution
  • Bangladesh has about 100,000 annual deaths from
    indoor air pollution

7
Indias Environmental Concerns
  • Indias main environmental concern is
    overpopulation.
  • It affects many of Indias other issues.
  • Indias population is expected to be about 1.6
    billion by 2050.
  • Such a large number of people will put a strain
    on groundwater supplies.
  • More water is needed to irrigate crops to keep
    up with the food supply.
  • If artificial fertilizers are used on crops, then
    drinking water may be affected.

8
Indias Environmental Concerns
  • Rivers such as the Ganges and groundwater are
    also polluted by toxic waste from industry.
  • Industry and vehicles pollute the air.
  • India has many small industrial workshops.
  • Because of this, it is difficult for the
    government to enforce laws to improve air and
    water pollution

9
Ganges River
  • Indias most sacred river
  • Used for funeral rites
  • Cremated bodies
  • (not) cremated bodies
  • Used by millions for drinking and bathing
  • Poor sewage systems drain directly into the river

Chinas Environmental Issues
  • Chinas fast industrial development and the large
    population have created major problems for the
    environment.
  • Pollution has increased and natural resources
    have been depleted.
  • Seven of the worlds ten most polluted cities are
    in China, according to a World Health
    Organization report.

15
Chinas Environmental Issues
  • Feeding the Chinese people is a huge task. Much
    of the food production occurs on the North China
    Plain.
  • The fertility of this plain is mostly because of
    the Huang He (Yellow River).
  • The Huang He used to regularly flood over its
    banks, often destroying crops.
  • This river is sometimes referred to as Chinas
    Sorrow.
  • To combat the widespread and disastrous flooding,
    the Chinese government has carried out large
    flood control and irrigation projects since 1949.

16
Chinas Population
  • To handle the population problem in China, the
    government instituted a one-child-per-family
    policy in 1979.
  • Couples that have only one child receive economic
    and educational benefits, while in cities,
    couples that have more than one child pay fines.
  • This population control policy has not been as
    successful as was hoped.
  • Many Chinese babies are put up for adoption.

17
Yangtze River
  • Chinas longest river
  • - 4,000 miles from the Northwest regions to the
    East China Sea
  • Passes through over 185 towns and villages (400
    million people)
  • Poor sewage drains millions of gallons into the
    river
  • Fertilizer run-off into the river
  • Millions of people use the river to catch fish
    (most have been contaminated by factory
    chemicals)

18
Yangtze River
  • Three Gorges Dam
  • Pros
  • Provide millions with Hydroelectric power
  • Control flooding in certain areas
  • Cons
  • Many plants and animals living near the river may
    face extinction
  • Built on an area prone to Earthquakes!
  • Three Gorges Dam
