Did you know that light pollution around the world, is increasing by 2% in area every year and by 2% in brightness every year? A third of the world’s population cannot see the Milky Way! Not only does this mean we are losing our precious dark night skies, but light pollution greatly affects human health and disrupts wildlife behaviours. But we can make a difference with just a small amount of effort.
Turn Off Your Outdoor Lights!
Turn off any unnecessary outdoor lights. Or choose outdoor lights that have sensors and only come on when needed. .
Update Your Lights and Save on Energy Use
Choose LED lights with “warm” colour qualities. LED’s are measured by colour temperature. A warm coloured light is 2200 degrees Kelvin (2200K). Ask your local light supplier if they have stock. You will probably surprise them with your knowledge!
Shield Outdoor Lighting to Point Down
If you have outdoor lights, check they are shielded to point downwards. Light should be directed only to where required and no brighter than necessary. Use timers or sensors, so light is turned off when not needed.
What is Sky Glow?
Skyglow is artificial light that causes light pollution up in the night sky, making it harder to see the stars. It creates a vast glow over cities. Shielding lights and pointing light down where needed, will make a significant difference.
Spread the word!
Many of us are completely unaware of the huge impact light pollution is having on us and our environment. Become a dark sky advocate! Chat to your friends and neighbours about the changes you’ve made to your home lighting. Ask your local council what they are doing to reduce light pollution.
Learn More
There are many organisations that provide valuable research on the effects of light pollution or how to reduce light pollution. Check out these great resources: Best LED’s or Light Pollution Solutions. Or attend one of Astrotourism WA’s great dark sky stargazing events.
