2. Standards
• SS7G10 The student will discuss
environmental issues across Southern and
Eastern Asia.
– a. Describe the causes and effects of pollution on
the Yangtze and Ganges Rivers.
– b. Describe the causes and effects of air pollution
and flooding in India and China.
5. Environmental Issues of South and
East Asia
The Yangtze River, the longest in Asia and the third longest in the
world, is expected to benefit 800 million people after the South-
to-North Water Diversion Project is realized. However, the river
on which so many already rely has suffered severe pollution far
beyond many people's imagination. By 2003, industrial and
urban daily wastewater exceeded 25 billion tons along the
Yangtze, 90 percent of which was untreated, and the drinking
water of more than 500 cities threatened.
The river is facing six big crises: deforestation, silting, earlier dry seasons, degraded drinking water,
threatened wildlife, damage to sluices and power stations, and damage to the river's natural self-
cleaning processes.
There is insufficient planning and not enough motivation to clean up their act, whilst the law provides
no consistent redress and offers too many loopholes.
Currently, 62 counties in Sichuan have no independent environmental supervision mechanisms, and
the existing 36 county-level mechanisms are unable to enforce environmental law.

What are the affects of polluted waters?
Fishing and fisheries – pollutants can outright kill the fish or create an
environment where algae can grow depleting the oxygen for the fish.
Oddly enough people now want bottled water, which takes 2 bottles of water
to make, and then the plastic bottle ends up back in the water as trash.
Sewage in the water produces bacteria such as Hepatitis A, E. coli, and giardia
which can cause gastroenteritis, cholera, chronic diarrhea and possible death.
Untreated trash such as fishing line or six pack holders can kill and maim

Pollution can become so bad in ports and harbors that trade could be
suspended to help keep the pollution from spreading.
Garbage can jam up Hydro-electric Power plants.
Garbage and pollutants can make irrigation useless, poisoning the very food
eaten.

18. Environmental Issues of South and

The Kyoto Protocol
The Kyoto Protocol is an
international treaty which
focuses on preventing or
decreasing global warming. Air
pollution is one of the main
concerns of global warming.
What causes air
pollution? When did the
first big (man made)
increase occur?

These images were acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua and Terra satellites. The image show Bangladesh wrapped on east and west by India. The Ganges River, flowing in from the west, and the Brahmaputra, flowing in from the east, join in Bangladesh and flow together out to the Bay of Bengal

Thick haze and fog settled over much of China on October 28, 2009. In this photo-like image captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite, the thickest of the gray-brown haze conforms to the low-lying contours of the Yellow River Valley and the western half of the North China Plain near the Luliang Mountains
This is a town on the Ganges about 250 miles from the Himalayas. As deforestation upstream enables dirt to be carried away by erosion from monsoons it flows down stream. When the water slows the dirt (silt) falls out of the water and builds up. Once built up it can block or divert water that comes down in the next monsoon.
