Presentation Transcript

  • Millions of gallons of sewage are dumped into the river.

  • Chemicals from agricultural runoff and industrial wastes (Nitrogen from fertilizers and arsenic from industry are the leading pollutants).


  • Many species of plants and animals along the river are disappearing.

  • Blue-green algae growth caused by high levels of nitrogen and phosphates. The algae reduces oxygen causing fish to die.

  • Contaminated fish are eaten by the Chinese which leads to other health problems.


  • Building more water treatment facilities.

  • Encouraging the building of sanitary landfills.

    However, the pollution continues to worsen in “China’s Toilet Bowl”

    Real solution: Education

Causes and effects of flooding



Flooding in india




Poor urban drainage

Building of dams


Inadequate town planning



When you alter the land the water is not able to go where it is supposed to go, which in turn develops into a flood!

Flooding in china





Ice blockage

Breaking of the levees


Towns established in flood plains

FLOODING (in China) !!!!

Causes and effects of air pollution

Air Pollution in China

Air Pollution in India

Air pollution causes
Air Pollution Causes

  • Enormous and growing population

  • Rapid growth of cities

  • Development of industry

  • Dependence on coal

  • Automobile emissions

  • Open fires in rural areas using wood,

    animal dung or coal as fuel

Air pollution in china



Coal burning

Few environmental standards enforced

HUGE numbers of cars on the roads

Acid Rain

Cancer- leading cause of death

1% of air is classified as safe to breathe by European Standards

Dissolving of limestone buildings

At the junction of Ningxia province and Inner Mongolia province, I saw a tall chimney puffing out golden smoke covering the blue sky, large tracts of the grassland have become industrial waste dumps; unbearable foul smell made people want to cough; Surging industrial sewage flowed into the Yellow River…”

Fan Jai Zhuang in Anyang City, Henan province, there is only one wall separating this village from the steelmaking furnaces. The villagers live in this heavily polluted environment where the village is under the iron rain every day. March 24, 2008

Shizuishan Industrial district in Ningxia province, the tall chimneys spitted out smoke and dust. Residents took preventive measure for the falling dust from the sky when going outside. April 22, 2006

In Inner Mongolia there were 2 “black dragons” from the Lasengmiao Power Plantcovering the nearby villages. July 26, 2005

Zhaozhuang village by the Hong River in Wugang City, Henan province, 66-year-old Zhao Bingkun suffering from esophageal cancer since 2004, after the second surgery, treatment cost already have reached over 200,000 yuan. His condition is in late stage, he is having fever everyday, waiting for death. April 7, 2009

People form Fanjiazhuang are ready to submit a complain filled with their fingerprints, to seek compensation for pollution damages. March 19, 2008

Yutian, Hebei province: Cyclists ride through a cloud of pollution produced by a nearby factory.

Vehicles and industry emissions

Road dust

Old diesel engines- lack of emissions

Cremations- use of butter ghee

Lack of pollution standards

50% of children suffer from Asthma.

Respiratory and cardiovascular problems

Premature death

Lung disease

1960 s green revolution
1960 pollution produced by a nearby factory.’S GREEN REVOLUTION

Rice & wheat are leading agricultural products in India!

This was India’s attempt to modernize Indian agriculture1) Continued expansion of farming areas

2) Double cropping existing farmlands

3) Using seeds with improved genetics

Expansion of farmland
EXPANSION OF FARMLAND pollution produced by a nearby factory.

The area of land under cultivation was being increased right from 1947.

This was not enough in meeting with rising demand.

Other methods were required. Yet, the expansion of cultivable land also had to continue.

So, the Green Revolution continued with this quantitative expansion of farmlands.

Double cropping
DOUBLE-CROPPING pollution produced by a nearby factory.

Double-cropping was a primary feature of the Green Revolution.

Instead of one crop season per year, the decision was made to have two crop seasons per year.

The one-season-per-year practice was based on the fact that there is only natural monsoon per year. This was correct. So, there had to be two "monsoons" per year. One would be the natural monsoon and the other an artificial 'monsoon.'

Seeds with improved genetics
SEEDS WITH IMPROVED GENETICS pollution produced by a nearby factory.

New types of seeds and grains were introduced

Indian Council for Agricultural Research

Developed new strains of high yield value (HYV) seeds, mainly wheat and rice but also millet and corn.

Uh oh there are problems
UH, OH! pollution produced by a nearby factory.THERE ARE PROBLEMS

Pesticides and fertilizers were made available… YIKES!

The chemicals the farmers used increased pollution in streams and rivers.

Some farmers found the new techniques too expensive to use!

Overall effects of air pollution
Overall pollution produced by a nearby factory.Effects of Air Pollution


  • The Asian Brown Cloud over parts of India and China

  • High rate of respiratory diseases (diseases of the lungs, bronchial tubes and trachea). The leading cause of death in China is respiratory and heart disease.

  • Acid Rain

  • Changes in climate

Solutions pollution produced by a nearby factory.

  • India is finding it difficult to enforce many of the laws that would limit air pollution. Why?

    • Desire for continued economic growth

  • China is trying to find ways to control pollution while maintaining economic growth.

  • China was able to reduce some pollutants by 45% before the summer Olympics.
