3 Gorges Dam Dam on the Yangtse river in China This structure will be able to be seen from space when it is completed 40000 people work on it from start to finish Cost: $28 billion Biggest dam in history Started 1994, finish 2009 1998 - worst flood in 44 years happened. People CRUSHED Yangtse floods regularly, very dangerous: Dam’s purpose is to stop these floods Also provides hydroelectricity and regular supply of drinking water “Symbol” of use of technology/modernization Yangtse’s tributaries are unpolluted, but main Yangtse is the most polluted river in the  world Coal power generators pollute a lot. Hopefully hydro power will reduce coal usage (very  dangerous and polluting, causes acid rain and heart disease)

Ultimately, this is a battle between Chinas past and its future....
