Light pollution is a pain, particularly to astrophotographers but to the human population in general, as you’ll discover in this video from Trevor Jones at AstroBackyard. The problems for astrophotographers are quite obvious. It ruins their photography, which seems like kind of a first world problem, but given the scientific discoveries that come through gazing at (and photographing) the stars, there is a bigger picture there, too.
But it’s not just astrophotographers and scientists that are suffering. There’s an even bigger picture that’s harming pretty much the planet’s entire population and affecting our circadian rhythm. This is the process by which our bodies naturally go through physical, mental and behavioural changes in a 24-hour cycle. It’s affected primarily by lightness and darkness and affects all living things – including people.
