The River Wye with Will Millard, BBC2, 2.45pm
THE writer and angler begins his three-part journey down the River Wye in the wild mountains of mid-Wales. He goes in search of the river’s source on the slopes of Plynlimon before learning how a local sheep farmer has diversified by turning some of his land into a destination for petrol-heads. Will explores how a legacy of heavy industry polluted the entire Wye catchment, acidifying its waters and damaging the ecosystem. He also takes a detour off the main river, up one of its tributaries to reflect on the benefits of being immersed in nature.
