Ep 4. The Danube

In this episode of Jeremy Wade's Mighty Rivers, titled "The Danube," our host ventures to the second longest river in Europe to uncover the secrets and challenges facing this iconic waterway. The Danube runs through ten countries, from Germany to the Black Sea, and is a vital source of freshwater and habitat for a diverse range of wildlife.

Jeremy begins his journey at the river's source in Germany, where he meets with scientists studying the impact of farming practices on the river's water quality. He also encounters a local fisherman who shows him the art of fly fishing for trout in the river's clear waters.

Moving downstream, Jeremy reaches Austria, where he investigates efforts to restore the river's natural floodplains. He joins a team of conservationists as they reintroduce native species like beavers and eagles to the area. Jeremy also learns about the challenges facing the Danube's sturgeon population, which has been pushed to the brink of extinction due to overfishing and habitat loss.

As Jeremy travels further east, he arrives in Hungary where he explores the impact of pollution on the river's ecosystem. He meets a local community that is working to clean up the river, using innovative methods like floating islands to trap pollutants and encourage the growth of aquatic plants. Jeremy also witnesses the incredible sight of thousands of migrating birds flocking to the river's wetlands.

Next, Jeremy discovers the Danube's role as a vital shipping route, as he witnesses a large cargo ship navigating the river's narrow channels. He also visits a hydroelectric dam, where he learns about the trade-offs between renewable energy and the impact on fish populations.

Finally, Jeremy reaches the Danube Delta, a vast wetland region where the river meets the Black Sea. Here, he meets with fishermen who rely on the delta's rich biodiversity for their livelihoods. He also witnesses the incredible spectacle of the delta's resident pelicans and cormorants, which gather by the thousands in the river's channels.

Throughout the episode, Jeremy offers insights into the challenges facing the Danube and its inhabitants, as well as the innovative solutions being developed to safeguard its future. With stunning visuals and fascinating storytelling, "The Danube" is a must-watch for anyone interested in the importance of our planet's rivers.
