Documentary Looks at Impact of Mekong Dams

An updated documentary, "Where Have All the Fish Gone?," examines the impacts of hydroelectric dams on the Mekong River. In particular, the film shows construction of the controversial Xayaburi dam, in Laos. The film screened recently at the Australian Center or Education in Phnom Penh. The Xayaburi dam, which would produce hydropower for market, has become a divisive issue among Mekong River countries. Critics say it could severely damage ecosystems on which lower countries like Cambodia and Vietnam rely. It is one of 11 dams under consideration on the lower Mekong.
