Let's reduce light pollution in Whitehorse and be able to see the stars and northern lights again.
But what can we do?
Well the City is doing a zoning bylaw update and so this is the time to get light pollution prevention measures (aka Dark-Sky provisions) put into the bylaw. Lots of other cites and towns have done it, so we can too. In fact, the International Dark Sky Association has even produced an example ordinance to help communities implement light pollution measures.
Why? It is summed up nicely in the introduction of IDS' Lighting Code Handbook:
"All of us live underneath the sky, and all of us need quality outdoor lighting. Careless use of outdoor lighting damages the night time environment in many ways for everyone, often decreasing security and safety or even creating hazards through glare and distraction where none would exist without the lighting. But the loss of the naturally dark star-filled sky is a tragic consequence for the environment and the human soul, akin to the loss of our forested landscapes or even the loss of fresh air we breathe. The night sky has been a canvas of our hopes and inspirations since we have been aware enough to raise our eyes from the ground. But our children are more and more growing up never seeing the stars, robbed of this inspiration of the ages.
It need not happen.
Careful and considerate use of lighting at night, using light only when it is really needed, where it is needed, and as much as is needed and no more, would unblanketed the stars in all but the largest cities. Compared to typical outdoor lighting practices, such "quality lighting" on average puts less than half the light into the sky, in some cases even less than one-tenth as much. Imagine it, in Whitehorse, a city of 20,000 residents, effective lighting could bring back the endless skyways and northern light filled skies of a village of 2000. The universe above could return to our towns and homes, to inspire the coming generations as it inspired the creators of Orion the Hunter with the Golden Fleece of stars tightly in his grip.
Quality lighting brings other substantial benefits as well. Lack of glare and excessive contrast brings improved visibility, especially to the aging eye. Elimination of wasted light saves money, energy and resources, which in turn reduces air pollution and carbon dioxide emissions caused by energy production and resource extraction. Good lighting returns a sense of balance to the night, and gives a quality appearance to our town when the sun goes down.
But poor lighting practice is rampant. Careless and excessive use of lighting in our outdoor environments causes extensive damage to the aesthetics of the night, at the same time that is compromises safety and utility, the very uses for which it is usually installed. Bad lighting hurts everyone. It starts a cascade of negative consequences--beginning with the loss of our views of the heavens, continuing through falling levels of safety and utility, irritation of our neighbour and wildlife, disturbance of the rhythms of day and night that are vital to many natural systems, damage the aesthetic appearance of our communities, wasted monetary and natural resources used to produce wasted light, and increased air pollution and carbon dioxide levels from wasted fossil fuels. There is nothing good that comes from bad lighting. Quality lighting costs less than bad lighting, in the long term and even usually in the short term. Everyone wins when lighting is done right. "
And the City supports this initiative, as stated in Sustainability section of the Official Community Plan, which says:
"13.1.3 The reduction of light pollution and energy usage of light fixtures shall be examined."

So let's turn this planning idea into reality. Please participate in the current zoning re-write process
and support implementation of light pollution prevention measures in
the bylaw. Also let City staff and councillors know that you support
seeing the stars and northern lights in Whitehorse.
If you, or someone you know, is particularly interested in this topic and want to form an ad-hoc advocacy group, then please contact me.
