Hi,

I’ve organized a free presentation that is coming up this Tuesday, short notice I know but if you are in Canada’s national capital area you may be able to make it.

For designers the presentation will give you something to think about when planning outdoor lighting.

Here’s the info…

The Unnatural Night
Light Pollution’s impact on the environment: on the health and behaviour of wildlife, and that of humans
Presented by: Robert Dick M.Eng. P. Eng., Carleton University

Artificial outdoor lighting has become a symbol of today’s society. Over 4 billion years, the chemistry of life developed subject to the day-night cycle of light and dark. This cycle changed during the past century with the widespread introduction of artificial lighting. We have accumulated data on light’s impact on the environment: on the health and behaviour of wildlife, and that of humans. Studies of wildlife and human health show how artificial lighting affects the behaviour and biochemistry of most life on Earth.

Artificial light is necessary to increase our ability to see after dark but it must be controlled to minimize the degradation of the environment. There are relatively simple lighting techniques that can be used that will limit this impact on the environment and that reduces its effects on human health.

7:30 p.m., Tuesday, February 16, 2010
