FOOTPRINTS!

Ardern has been looking at footprints more and reflecting on "how we leave impressions, some temporary, some long, some ancient, but none permanent (on the geological time scale at least!)." 
He has collected images of prints in mud - some pigeon, fennec fox and lizard footprints (images above) and says " I'm thinking about how we're moving away from having footprints at all, contemplating new technological developments, from trackless modes of transport like seafaring to digital technologies which leave little physical trace. Considerations of carbon footprints and how we can get to a stage where we leave none of those either"
