In addition, you can learn more about light pollution and how you can help save our starry skies watch "Losing the Dark" from the International Dark Sky Association and Loch Ness Productions. Starry skies are a vanishing treasure because light pollution is washing away our view of the cosmos. It not only threatens astronomy but also disrupts wildlife, and affects human health. The glows over cities and towns — seen so clearly from space — are testament to the billions of dollars spent in wasted energy by lighting up the sky. The video introduces and illustrates some of the issues regarding light pollution and suggests three simple actions people can take to help mitigate it.
