As more and more of us yearn for a life in the country, Matt Baker and Charlotte Smith roll up their sleeves on a community farm in Herefordshire. Matt helps to save a bee colony and harvests fruits from their walled garden. Charlotte hand milks Snowdrop, one of the community's dairy cows, before making her own butter. It's the final challenge for Dwayne Fields and his gallant team of adventurers as they set out to climb Wales's biggest mountain, Snowdon. Tom Heap investigates why some plant-based products on supermarket shelves may not be as good for us as we might think.
