Dams and wildlife in the USA, films at Rotterdam festival

This trailer video from the USA says about itself:

This powerful film odyssey across America explores the sea change in our national attitude from pride in big dams as engineering wonders to the growing awareness that our own future is bound to the life and health of our rivers. Dam removal has moved beyond the fictional Monkey Wrench Gang to go mainstream.

Where obsolete dams come down, rivers bound back to life, giving salmon and other wild fish the right of return to primeval spawning grounds, after decades without access. DamNation’s majestic cinematography and unexpected discoveries move us through rivers and landscapes altered by dams, but also through a metamorphosis in values, from conquest of the natural world to knowing ourselves as part of nature.

This film is at the Wildlife Film Festival in Rotterdam, the Netherlands. Like this other film:

This trailer video says about itself:

‘Return of the River’ follows a group of people who attempt the impossible: to change the opinion of a town and eventually the nation to bring two dams down. The community comes to consensus, launching the largest dam removal in history, and showing the way to a more sustainable future. Infused with hope, the film explores an unlikely victory for environmental justice and restoration, unfolding on the Elwha River in Washington State.
