..., illuminating nothing.

A continuously illuminated emergency stairwell this evening. No doubt Heath and Safety would approve, but having just listened to the 2011 Swarthmore Lecture on the global climate crisis, reinforcing just how unsustainable our wastage of resources is (not that I didn't already know) such H&S expectations seem particularly crass. That is, of course, a tad OTT given the enormity of uneducated wastage at large, but I'd taken the photo earlier and am looking at it slightly differently now.

Learnt something new from the lecture: the concept of Earth Overshoot Day - the date each year when we've already used up the amount of resources the planet could replenish that year. September 27th last year.
