- Three Gorges Dam Impacts
- Social
- Possitive: 1)Dam provides jobs for building process
- 2)Better electricity+water supply, better lifestyles.
- Cultural/relligious sites lost, Yangtze Gorges Historic Site disappear.
- People upstream,1.9 million will lose homes under wate. People need to relocate to higher colder areas.Poor soil there, slopes steeper, harder to make a living from farming.
- Few human rights in China, people forced to leave homes, especially poor.Forced by China Government.
- People not told anything about why or where they r moving etc.
- Few human rights in China, people forced to leave homes, especially poor.Forced by China Government.
- No compensation for homes lost landslides, fault of dam.Ppl made homeless, people can't settle down in area. Local officials no help.
- Possitive: 1)Dam provides jobs for building process
- Environmental
- Negative: 1)Huge impact on wildlife of area. Yangtze River Dolphins, Chinese Alligators etc. could be extinct.Habitats destroyed by dam + reservoir.
- 2)Floods fertile farmland. creates methane so vegeatation rots.Fish breeding grounds lost/altered.
- 3) Dam built in earthquake zone,RISK, China regular earthquakes. Previously on that site 2 dams collapsed 1/4 million ppl died.
- 4)High water level next to land causing landlslides, weakening land, breaking people's homes. Frequency of landslides will increase.
- 3) Dam built in earthquake zone,RISK, China regular earthquakes. Previously on that site 2 dams collapsed 1/4 million ppl died.
- 2)Floods fertile farmland. creates methane so vegeatation rots.Fish breeding grounds lost/altered.
- Positive: 10Less dependency on coal, biggest user/producerof coal worldwide.Less dirty field,toxic smog,acid rain, millions of tonnes harmful coal dust,mines,pollution,less disease/defects.
- 2)Flood controll - protects 10 million people downstream frm flooding, important coz 300,000 died be4.
- Chief Engineer: dams collapsed be4 coz of torrential rain, developed engineering, now safe.
- Clean water supply to more people.
- Less global warming which causes sea levels to rise, large area of China;s coast would have flooded.
- 2)Flood controll - protects 10 million people downstream frm flooding, important coz 300,000 died be4.
- Negative: 1)Huge impact on wildlife of area. Yangtze River Dolphins, Chinese Alligators etc. could be extinct.Habitats destroyed by dam + reservoir.
- Economic
- Positive: 1)Dam generates 18,000 megawatts of electriciy, 1/9 of China's.
- Renewable, less money spent on coal mining etc.
- Negative:Cost 50 billion dollars to build, really expensive.
- May not be worth the money.Dam slows river flow, so river collects more dirt+sediment, eventually stop working, generates less and less electricity as it fills. Short term benefit.
