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.
Pollution of the Yangtze River Causes include – Sewage runoff Industrial runoff Agricultural runoff
Pollution of the Yangtze River Effects include – Dead zones Lack of drinkable water Deformities in animals Multiple health issues na-attacks-water-pollution-and-plans- massive-investments
Pollution of the Ganges River Causes include – Industrial runoff Human waste Human pollution (trash) Bodies (http://www.all-about-india.com/Ganges-River- Pollution.html)http://www.all-about-india.com/Ganges-River- Pollution.html
Pollution of the Ganges Effects include – Health issues Death Lack of drinkable water Negative impact on economy
Air Pollution in India Causes – Transportation Industry Household pollution Coal power stations Large population Effects – Death (over 2million/year) Lung cancer Lung infections chronic obstructive pulmonary disease.
Air Pollution in China Causes – Rapid economic growth Burning coal Population growth Transportation Effects – Respiratory disease Lung cancer Asthma Brown cloud Acid rain
Will the completion of the Three Gorges Dam on the upper Yangtze River help with flooding?
Pros and Cons of the Three Gorges Dam Will generate electricity-clean & inexpensive A renewable energy source Will control flooding Can store river water in case of a drought Will improve transportation Requires the flooding of entire valleys & scenic areas Disrupts natural seasonal changes in the river Ecosystems can be destroyed Natural flooding cleans out silt The silt that washes downstream provides fertile soil
Facts about the Three Gorges Dam “Future Wonder of the World” When completed it will be the largest hydroelectric dam in the world Will be more than 1 mile long Will be almost 600 feet tall Will cost about 24 billion dollars 20 years construction time!!
