14/11/22 Indoor grown wheat, new SSSI in Cornwall, tree planting targets

We hear how wheat grown indoors could help with food security. Plans to turn a large swathe of heathland in West Cornwall into a nationally protected site have left some farmers fearing for their livelihoods. We're going to be talking about trees all week. Planting millions more is a major target for the UK, a target that with the exception of Scotland we are good at missing. There are arguments about which trees to plant and where to plant them, particularly if farmland is targeted for woodland creation. Presented by Charlotte Smith and produced by Beatrice Fenton.
