When I go for a walk, it’s often to the soundtrack of a podcast. I realise having headphones on splits my attention between where I am and where the podcast takes me, and I miss out on the sounds of the environment I’m in and send signals to others not to approach. This is not ideal. But I value what I learn in the podcasts, and I doubt I would otherwise carve out time to listen to them. The Plodcast from the BBC’s Countryfile Magazine is a series of conversations that take place between people as they’re out walking, e.g. #228 “A walk with Robert Macfarlane along a Cambridge chalk stream to its magical spring”, or #305 in which Sophie Pavelle walks along the River Otter and explains “why some species work together, while others exploit host animals as parasites.” I’ll likely never go for a walk with Robert Macfarlane or Sophie Pavelle, but The Plodcast gives me a sense of what that might be like.
