Yangtze (yangzi) river, china: 3rd or 4th longest river in the world, ya(cid:374)gtze river i(cid:374) 3,937 (cid:373)iles" lo(cid:374)g, floods frequently. Floods claimed more than 1 million lives during the last. First proposal to build a damn in 1919. After terrible floods in 1950, feasibility study was ordered to study dam construction for flood control. Created reser(cid:448)oir hu(cid:374)dreds of feet deep a(cid:374)d al(cid:373)ost 4(cid:1004)(cid:1004) (cid:373)iles" long.

Arguments for and against the building of the dam. About 1. 13 million persons have been displaced and relocated. Hep (hydroelectric power) as a source of fuel is cleaner than coal burning. This will result in a reduction of greenhouse gas emissions. No nuclear power plants therefore no radiation. The extra electricity will stimulate new manufacturing enterprises which will bring new job.
