How You Can Reduce Light Pollution Even if you don’t have an industrial source of light pollution in your area, we all have a role to play in reducing light pollution. This simply involves turning off lights that are not required, directing light rays to the ground, and blocking light from travelling upwards and into the sky. The International Dark-Sky Association recommends the following principles for lighting: ≥ Turn off lights when you no longer need them. Consider using motion sensors so that lights are only on when you need them. ≥ Eliminate the upward direction of lights. Practically speaking, this means directing lights to the ground and choosing fixtures with shields that limit the amount of light that scatters upwards. ≥ Use low colour LED lights. Blue light scatters more than white light and has a disruptive effect on melatonin production, which interferes with the circadian rhythm of humans and animals alike. For more information on what you can do to make your outdoor lighting dark-sky friendly, check out the International Dark Sky Association here: darksky.org Boating Safety in a Nutshell: ≥ Share the waterways – courtesy, courtesy, courtesy ≥ Boaters have legal civil responsibility for their wakes ≥ Boaters are legally responsible to do everything possible to avoid collision, even if they have the right of way “Every vessel shall at all times proceed at a safe speed so that she can take proper and effective action to avoid collision and be stopped within a distance appropriate to the prevailing circumstances and condition.” – Canada Shipping Act 2001 Example of a lighting fixture that shields light from scattering upwards.
