Saving the River Jordan and the Dead Sea: A Water Crisis Uniting Enemies | Water is our Future (4/5)

We’re witnessing the comeback of a small river and an entire landscape. For decades the Emscher in the Ruhr District was the most polluted river in Europe. Now it’s being returned from an industrial sewer to a natural river system. With the help of waste water treatment plants, liberated river beds and returning animal species, a unique natural region is blossoming – one with a very special industrial heritage. ------- Chapters ▷ 00:00 - Introduction ▷ 00:58 - The Emscher Becomes a Sewer ▷ 02:11 - A Plan to Restore the River ▷ 05:14 - Mining, Sewage, and Pollution ▷ 07:59 - The Filthiest River in Europe ▷ 09:54 - Fighting for a Cleaner Emscher ▷ 12:10 - Citizens' Protests Begin ▷ 16:06 - Building a New Sewage System ▷ 21:35 - A Rare Fish Returns - The Bullhead ▷ 25:25 - From Steelworks to Lake Phoenix ▷ 29:40 - Nature Comes Back to the Ruhr ▷ 33:12 - The Protected Emscher Bullhead ▷ 35:12 - A Region Reinventing Itself ▷ 37:07 - Flood Protection and Wetlands ▷ 39:02

Hardly a drop of water makes it to the estuary of the Colorado. Once it reaches Mexico, after its journey through the Rocky Mountains, the Grand Canyon and Nevada, the river is dry – and has been for decades. The demand for water in its catchment area is just too big. But conservationists are now working to make the estuary green again. They’re persuading people along the Colorado to give some of its water back to the river. ------- Chapters ▷ 00:00 - Introduction ▷ 00:51 - The Colorado River and Its Journey ▷ 04:19 - Hoover Dam and Lake Mead ▷ 06:03 - Drought and Water Shortage ▷ 08:02 - Las Vegas - A Desert Playground ▷ 09:36 - Water Cops and Conversation ▷ 12:50 - Desert Gardens and Adaptation ▷ 18:34 - Golf Courses and Water Use ▷ 21:25 - Recycling Water in Las Vegas ▷ 24:13 - Lower Colorado and the Mojave Desert ▷ 26:18 - Imperial Dam and Farmland ▷ 28:52 - Feeding America from the Desert ▷ 33:11 - Settlers and Water Rights in Yuma

For centuries the Dutch have tamed the sea with dykes and criss-crossed their country with canals and waterways. But climate change is whipping up storms and raising the sea level. The Netherlands is now seeking a new pact with water in order to protect the low-lying country. They’re making use of state-of-the-art technologies and the power of nature – and are systematically making space for the water elsewhere. ------- Chapters ▷ 00:00 - Introduction ▷ 00:52 - The Dutch and the Sea ▷ 02:31 - Amsterdam Below Sea Level ▷ 06:11 - Battling the Waves with Sand ▷ 07:47 - The Sandmotor Experiment ▷ 11:10 - 1953 Flood Disaster ▷ 12:08 - The Delta Works ▷ 14:03 - Oysters and the Eastern Scheldt ▷ 17:44 - Oyster Reefs as Natural Defenses ▷ 19:32 - Windmills and Polders ▷ 23:06 - Living with the Risk of Floods ▷ 25:33 - Room for the River ▷ 30:17 - Farmers Forced to Adapt ▷ 35:35 - New Landscapes in the Polders ▷ 37:28 - Nature Returns - De Biesbosch Park ▷ 41:37

The arc of Tyrrhenian volcanoes that stretches from Pozzuoli north of Naples to Sicily is one of the most active – and little known – in the world. The archetypal “restless volcano” is also close to one of Europe’s most densely populated areas. Though it hasn’t erupted since 1538, it has shown worrying signs on and off since the 1970s. The Campi Flegrei is an area north of Naples that occupies a 20km wide volcanic crater at sea level. Possibly more dangerous than Vesuvius but less imposing as a Volcano is the 20 km wide caldera known as the Campi Flegrei. While Vesuvius rises high out of the Campania plain the Campi Flegrei volcano is at sea level and visibly active. The area around the volcano is densely inhabited: Pozzuoli is a working class suburb of Naples. It has been a place of religious cult since the first Greek settlements. The people of Pozzuoli live with the risk of a catastrophic explosion, and yet go on with their daily lives. In the 1970s and 80s many of the inhabitants of

York Hovest spent three years traveling the world's oceans with his camera & diving equipment, in search of solutions to one of the most pressing challenges of our time: saving the oceans. "Heroes of the Sea" is an encounter with people who are passionately fighting a hard - yet not always promising - battle; people who are striving to save the oceans from growing plastic waste, limitless overfishing and the supposedly unstoppable climate change with visionary ideas. In his award-winning documentary, York Hovest takes us on an adventurous hunt for illegal fishermen off the coast of West Africa and lets us experience first-hand the death grip of giant fishing nets. In Thailand, York introduces us to Andrew Hewett, a Briton who is doing everything he can to save the coral reefs from the effects of global warming and mass tourism. On the beaches of Haiti, buried under meter-high mountains of garbage, Hovest meets David Katz, who has developed a recycling system to combat plastic pollution and poverty at the same time. With his first cinematic work, the National Geographic book
