The Milky Way, photographed by John H at Narara Ecovillage, is a reminder of what we lose to light pollution.
A growing body of evidence has linked light pollution directly to ecological disruption and harm to human health, not to mention unnecessary energy consumption.
What can you do about it? Shield outdoor lights, use warm-coloured globes, switch off what you do not need, and advocate for dark-sky-friendly lighting in your neighbourhood. The night sky is a shared treasure worth protecting.
