Frazzled? Go for a walk in the woods. It'll calm you down, fill your nose with lovely smells, and reset your eyes to room temperature. But why?  According to today's guest, humans evolved to need to chill out in natural environments. It gives us nice chemicals like serotonin, is good for long term mental health, and generally resets our stress alarms. This is the idea of Biophilia, and it's rather nice. Joining Dave this episode is Dr Lauren Hall Ruddell - a  journalist and naturalist  who has spent many years thinking  about the restorative power of being in nature.  We talk about all things biophilic, and how losing the nature we evolved to need is one of the biggest tragedies of the climate crisis. The opening poem thingy is an extract from "A Transparent Eyeball" by Ralph Waldo Emerson, read by Ruth Everett.
