Light Pollution is the Fastest Growing Pollution in the World
Light Pollution - What is it?
Light Pollution is excessive, misdirected, or obtrusive Artificial Light (usually outdoor).
Industrial sites, car dealer exhibitions, business buildings (after business hours) and the majoritry of private properties use excessive illumination to attract customers or to feel safer.
Harmful side effects such as disruption of nocturnal wildlife, glare, trespassing light into neighbours bedrooms or brightening up the night sky are rarely taken into account.
The "National Light Pollution Guidelines for Wildlife Including marine turtles, seabirds and migratory shorebirds,January 2020" (Australian Government) are very clear and the rules are easy to understand and easy to follow.
Since the introduction of very bright LED lights artificial lighting has massively increased. Lighting has become "cheap"... Not only on private properties but also in street lighting. Upgrading high pressure sodium streetlights with LED's has been managed very badly in many places resulting in heavy glare and unnecessary light pollution.
There are a few rules property owners can use to substatially reduce light pollution.

Nightlife in large cities is part of our life style. Glamarous illumination is part of it - illuminating the sky above these places is hard to avoid.
But we should acknowledge that the Milky Way will no longer be visible nor a night sky with shining stars...
However in smaller cities and in rural areas where there are still nocturnal animals living we should preserve the dark nights. It's their habitat...
Artificial lights should be used with care and as limited as possible. If illumination is necessary we should light only what is needed and when it is needed.
It's our responsibility and the dark nights will be back in our hands.
