I have been doing some research for a project presentation that I have to do for my Environmental Ethics class. I came across this film, link below, which talks about dams and their environmental impact. They focus on the native fish in the area and how many of the local dams are no linger viable, or were never useful to begin with. They source actual experts, which is typically rare in an environmentalist documentary, who presented well documented studies. They show both sides of the issue and it is crystal clear which types of ideologies each group has.

The dam supporters argue from an anthropocentric mindset. They would say things like, "Yeah, I changed the environment, but I did it for the benefit of mankind," and the way they say it is as if that is a justified rationalization. The dam opponents, on the other hand, argue from an ecocentric mindset. They say things along the lines of, "The dams have interfered with the breeding cycle of the native fish and seriously reduced their population," which they then show videos of the fish populations from before the dams went up.

Towards the end they show two damns that were demolished and the effects on wildlife. Within a year the population of the fish is higher than it had ever been after the dam was built, solidifying the ecocentric argument.

It is on Netflix and elsewhere. Check it out if you are into environmental type stuff. Speaking of, is there a conservationist group here? If so I am unaware of them.
