Light pollution isn't just a problem for astronomers. It means the loss of an amenity for all of us now and the generations that follow. It affects the natural world, can ruin our health, wastes resources, and what's more, we're paying for it!
Absolutely right, Lori. Plants also have their biological rhythms and light is important to them.
I remember going to an evening event at Kew Botanical Gardens and one of the glasshouses was open. They use green lighting. It's quite pretty, but the main point would be that plants aren't responsive to green light, so it minimized any possible damaging effects.
Canyonlands National Park, part of the National Park Service's Southeast Utah Group has just received Gold-Tier International Dark Sky Park status by the International Dark-Sky Association (IDA). It's been a national park since 1964 and has spectacular daytime scenery and spectacular night skies. For many visitors it's the first time they've ever seen the Milky Way.

some man-made form of brightness has overshadowed the night sky's brilliance across most of the planet. That means health impacts on plants, animals and humans, and, of course, an utter loss of natural beauty as we lose the ability to see the constellations.
But a new study published in the journal Park Science suggests that national parks could be all that's left of the unpolluted night sky. There are hopes that collaborative efforts with local communities could cut back on some of the light pollution that destroys our view of the sky.
