What is Light Pollution?

The inappropriate or excessive use of artificial light – known as light pollution – can have serious environmental consequences for humans, wildlife, and our climate. Components of light pollution include:

• Glare – excessive brightness that causes visual discomfort
• Skyglow – brightening of the night sky over inhabited areas
• Light trespass – light falling where it is not intended or needed
• Clutter – bright, confusing and excessive groupings of light sources
