2. Air Pollution
īAsian Brown Cloud
īĄ
īĄ
īĄ
2 mile deep brown haze
Respiratory problems
Climatic Changes
īˇ
īˇ
īĄ
Floods
Acid rain
Blocks Sunlight
īˇ
Destroys crops
īCauses:
īĄ
īĄ
īĄ
Industrialization
High population in Urban
areas
Burning wood and other
biomass material
īˇ
Many areas lack electricity
or other cleaner energy
sources
6. Air Pollution
Chinaâs is the worldâs fastest growing economyâwith
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. Indiaâs Environmental Concerns
ī Indiaâs main environmental concern is overpopulation.
ī It affects many of Indiaâs other issues.
ī Indiaâs population is expected to be about 1.6 billion by
2050.
ī Such a large number of people will put a strain on
groundwater supplies.
ī More water is needed to irrigate crops to keep up with the
food supply.
ī If artificial fertilizers are used on crops, then drinking water
may be affected.
8. Indiaâs Environmental Concerns
īRivers such as the Ganges and groundwater are also
polluted by toxic waste from industry.
īIndustry and vehicles pollute the air.
īIndia has many small industrial workshops.
īBecause of this, it is difficult for the government to
enforce laws to improve air and water pollution
9. Ganges River
īIndiaâs most sacred river
īĄ Used for funeral rites
īĄ Cremated bodies
īĄ (not) cremated bodies
īUsed by millions for drinking and bathing
īPoor sewage systems drain directly into the river

14. Chinaâs Environmental Issues
īChinaâs fast industrial development and the large
population have created major problems for the
environment.
īPollution has increased and natural resources have
been depleted.
īSeven of the worldâs ten most polluted cities are in
China, according to a World Health Organization
report.
15. Chinaâs Environmental Issues
ī Feeding the Chinese people is a huge task. Much of the food
production occurs on the North China Plain.
ī The fertility of this plain is mostly because of the Huang He
(Yellow River).
ī The Huang He used to regularly flood over its banks, often
destroying crops.
ī This river is sometimes referred to as âChinaâs Sorrow.â
ī To combat the widespread and disastrous flooding, the
Chinese government has carried out large flood control and
irrigation projects since 1949.
16. Chinaâs Population
īTo handle the population problem in China, the
government instituted a one-child-per-family policy
in 1979.
īCouples that have only one child receive economic
and educational benefits, while in cities, couples that
have more than one child pay fines.
īThis population control policy has not been as
successful as was hoped.
īMany Chinese babies are put up for adoption.
17. Yangtze River
īChinaâs longest river
- 4,000 miles from the Northwest regions to the East China
Sea
īPasses through over 185 towns and villages (400
million people)
īPoor sewage drains millions of gallons into the
river
īFertilizer run-off into the river
īMillions of people use the river to catch fish (most
have been contaminated by factory chemicals)
18. Yangtze River
īThree Gorges Dam
īĄ
Pros:
īˇ
īˇ
īĄ
Provide millions with Hydroelectric power
Control flooding in certain areas
Cons:
īˇ
īˇ
Many plants and animals living near the river may face extinction
Built on an area prone to Earthquakes!
