Paul Whitehouse: Our Troubled Rivers

Paul explores the change in the water industry since privatisation in 1989 and what regulations are in place when it comes to sewage discharge into rivers. He meets concerned locals in Yorkshire looking to highlight the health of the River Wharfe, a conservationist who warns of the ecological decline in iconic Lake Windemere, and the man at the front of the battle for the country's waterways, Feargal Sharkey.

Paul continues his journey, travelling to Wales and the south of England. Visiting the River Wye, he sees how explosions of algae are part of a cocktail overwhelming the habitat.
