The cellist, singer and environmental campaigner Sarah Smout takes us for a beautiful summer walk along the River Wharfe in North Yorkshire. Along the way she explains how her love of the natural world inspires her music and stops to play, sing and read one of her poems. Then we head up to Fleet Moss where a five-year-long project has been restoring the badly damaged peat bog - which is vital for carbon capture. Jenny Sharman of the Yorkshire Peat Partnership joins us to tell the fascinating story behind the work - then Sarah sings the song inspired by it.
