- Environmental issues with the Three Gorges Dam
Environmental issues with the
Three Gorges Dam, which is currently under construction on Yangtze River, include degraded water quality, detriments to wildlife, potential riverbank collapses, and potential silt related falling of coastal areas.
Currently, the quality of water in the higher banks of Yangtze is slowly worsening, due to the dam's preventing dispersal of
pollutants; algal blooms have risen progressively since the dam’s construction; and soil erosionhas increased, causing riverbank collapses and landslides.cite news | url=http://www.time.com/time/world/article/0,8599,1671000,00.html | title=China's Three Gorges Dam Under Fire | date = 2007-10-12| publisher = Time | accessdate=2008-01-13] The report detailing this was officially released in September 2007.

Xinhua News Agencyalso reported that tens of billions of yuan had been spent to prevent pollution and geological disasters by tree planting, measures to maintain biodiversity, shutting 1500 polluting industrial and mining enterprises and building 70 sewageand waste treatment plants, all of which are "progressing well."

BaijiYangtze river dolphin. Though it was close to this level even at the start of construction, the dam further decreased its habitat and increased ship travel, which are among the factors causing what will be its ultimate demise. In addition, populations of the Yangtze sturgeonare guaranteed to be "negatively affected" by the dam. [cite news

While logging in the area was required for construction which adds to erosion, stopping the periodic and uncontrolled flooding of the river will lessen bank erosion in the long run. The build up of
siltin the reservoir will, however, reduce the amount of silt transported by the Yangtze River to the Yangtze Deltaand could reduce the effectiveness of the dam for electricity generation and, perhaps more importantly, the lack of silt deposited in the peninsula could result in erosion and sinking of coastal areas.cite news
