Why 94% of flowing waters have lost their native animal species
In short: From mountain torrents to lowland meanders, our streams are facing a silent crisis. This documentary follows a typical stream from source to mouth to reveal why these vital ecosystems are in decline.
The film explores the delicate balance of stream habitats, highlighting species such as the fluorescent-shelled stone crayfish, the fire salamander, and the bullhead—a fish with a specific 'eating disorder.' It examines the three distinct disasters that strike these habitats throughout the year and investigates the factors leading to a state where only one in a thousand streams in Germany remains considered intact.
By tracing the journey of a stream, the documentary unveils the broader battle against climate change and the urgent steps required to protect these vanishing ecosystems.
