Light is changing, dramatically. Our world is getting brighter -
you can see it from space. But is brighter always better?
Artificial light is voracious and spreading. Vanquishing precious
darkness across the planet, when we are supposed to be using less
energy. The quality of light has altered as well. Technology and
legislation have crushed warm incandescent lighting in favour of
harsher, often glaring alternatives. Light is fundamental - it
really matters. It interacts with life in profound yet subtle ways:
it tells plants which way to grow, birds where to fly and coral
when to spawn. It tells each and every one of us when to sleep,
wake, eat. We mess with the eternal rhythm of dawn-day-dusk-night
at our peril. But mess with it we have, and we still don't truly
understand the consequences. In Incandescent, journalist Anna Levin
reveals her own fraught relationship with changes in lighting, and
she explores its real impact on nature, our built environment,
health and psychological well-being. We need to talk about light,
urgently. And ask the critical question: just how bright is our
future?
