Matt, Ellie and Steve are in West Sussex, where Matt explores the phenomenon of 'champing' - where people pay to stay in churches. He also meets the man who listens to trees and discovers the surprising world beneath their bark. Ellie meets Maya Leonard, a self-proclaimed 'insect activist', to hear how beetles are just as important at pollinating plants as bees. Steve is with the volunteers, calling themselves gleaners, who hope to put an end to food waste. Plus Tom looks at the problem of untreated sewage being dumped in rivers, and Adam and Charlotte announce the winner of Countryfile's Farming Hero Award
