Charlotte Smith and Matt Baker are at Lower Hampen Farm in the Cotswolds to meet Lydia and Clive Handy, who have turned back the clock to adopt a more traditional approach to farming. Matt weaves a yarn, using wool from the farm's rare breed sheep, whilst Charlotte lifts the lid on soil microbiology and how it could impact the way we grow our food in the future. Adam looks at how the discovery of a major food fraud has impacted an already beleaguered British pig industry, and Tom investigates how food price inflation could impact the nation's health.
