I live in Sheffield, which is about as green as cities get in the UK. I try and walk every day - you can walk from my front door through woods all the way into the Peak District and stand a good chance of not seeing more than a couple of souls. Lately my son has started joining me and honestly, it’s just the most nourishing part of my life at the moment. I am not sure I could survive on the huddled trees and pruned green rectangles disbursed throughout somewhere like London, and even the more extensive parks just don’t feel real to me.
