Light Pollution

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!

Light Pollution

The reports that I used for the article are available online.

(1) Deda, Elbertzhagen & Klussmann, Secretariat of the Convention on the Conservation of Migratory Species of Wild Animals (UNEP-CMS)
Light Pollution and the Impacts on Biodiversity, Spaces and Their Habitats

(2) Gallaway, Olsen & Mitchell, The Economics of Global Light Pollution

(3) The Royal Commission on Environmental Pollution,
Artificial Light in the Environment

Nice article. Important info.

Even plants need rest time. They are stimulated by light and most species require dark periods to rest. Light pollution weakens them.

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.

For more information about any aspect of light pollution, including practical lighting tips, check out the International Dark-Sky Association.

The British Astronomical Association's Campaign for Dark Skies also has a wealth of information.

Here is a night time picture taken in Yosemite National Park in California. It's a reminder of what is being stolen from us and plants and animals around the world.

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.

Here's what 2/3 of Americans can't see at home. The Sierra Club reports that
Quote:
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.
