John Craven meets Linda Sharp, the UK's first female European champion, who helped shape Welsh surfing culture in the 1970s, and further along the coast, John joins Swansea's Surfers Against Sewage at one of their monthly beach cleans to help combat the never-ending battle against beach litter.Margherita Taylor discovers the magical landscape of the Kenfig sand dune system, which is home to a wealth of flora and fauna, including one of the UK's rarest wild flowers – the fen orchid. Joe Crowley explores how nature could be threatened by the UK's growing demand for water, and Adam catches up with our young farmers to discuss the highs and lows of starting out in agriculture.
