For Simon Evans, his passion for rivers has always run deep. If you'll excuse us the pun there!
While his friends were down the pub, he was walking along canals, always fascinated by the beauty and diversity of our waterways.
That passion led him to his current role, as chief executive of the Wye and Usk Foundation, an environmental charity that works to restore and protect the rivers Wye and Usk.
In an inspiring and thought provoking conversation, we hear from Simon about why our rivers matter, the huge challenges facing them, and why we should all be fighting to protect them.
