Promoted and supported by Patagonia, DamNation takes an in depth look at an environmental issue which few Americans are aware of. This environmental documentary explores the importance of dams with reference to their history in America, influence on culture, impact on the environment, importance to agriculture, and energy efficiency. The main environmental issue concerning dams which is discussed throughout the film is the impact of dams on salmon spawning, America's response to salmon spawning with fish hatcheries, and the conservational inefficiency of (and harm caused by) fish hatcheries. The film also looks at the history of government funded dam construction and cultural backlash and call for dam removal. Not only have dams destroyed salmon spawning routs, but also flooded areas of incredible beauty and of immense cultural and historical importance to Native Americans. DamNation bring to light the hypocrisy and corruption behind the construction and maintenance of many major dams on rivers such as the Snake and Colorado. Released in 2014, this powerful and visually stunning documentary calls for major revisions and reevaluations of the value of all dams in the US. DamNation does a great job presenting the several different, complex issues surrounding dams in America, however it is biased. The film takes the effort to interview dam workers and hydro power supporters; however, the film mostly focuses on the negative effects of dams and why removal necessary. DamNation is considered both a documentary and adventure film. Documentaries often struggle to maintain the interest of the audience but DamNation is not just able to entertain the audience with action and visually beautiful shots, but also inspire them stand on environmental issues and to enjoy the outdoors. I would recommend this film to all young adults and anyone interested in environmental issues.
