confuse Friday night lights with moon
issue is a bird called the Newell's shearwater, which numbered about 80,000 in the mid-1990s. Its population has plunged 75 percent in recent years as Kauai grew in size and added more lights that confuse the birds.

The lights are on - but is anybody home?
They may be fond of telling us to recycle more, drive less and generally lead a greener, more sustainable lifestyle - but do politicians ever listen to themselves?

Light pollution rubs out stars
Nearly 2,000 people took part in the star count. Only 2 per cent of participants said they could see more than 30 stars, and 54 per cent saw fewer than 10 stars in Orion. Not surprisingly, the fewest stars tended to be seen in the more built-up areas

Investigation of Lighting Levels for Pedestrians

Investigating whether a crime reduction measure works
There is a tendency for people to be worried by the dark, perhaps with good evolutionary reason and it may well be that the majority feel safer from crime with brighter exterior lighting at night. However, the question is whether people are in reality safer. Lighting may aid and encourage criminal activity more than it reduces it. Of course lighting at night is needed to see where we are doing and avoid hazards.
Bright Lights, Big Cancer
A woman's blood provides better sustenance for breast cancer just after she's been exposed to bright light than when she's been in steady darkness, researchers led by David E. Blask of the Bassett Research Institute in Cooperstown, N.Y., report.
"Light at night is now clearly a risk factor for breast cancer," Blask says. "Breast tumors are awake during the day, and melatonin puts them to sleep at night." Add artificial light to the night environment, and "cancer cells become insomniacs," he says.

Is light pollution killing our birds?
The authors think that the increasing numbers of urban street and security lights must have a measurable impact on the environment, as insects fly around the lights all night and eventually fall to the ground exhausted, no longer having the energy to feed themselves or to procreate. Consequently, with lights often left on all night, 365 nights a year, the number of insects must be significantly reduced.
Impact of Outdoor Lighting on Man and Nature
Dear Minister,
I hereby present you with a Health Council advisory report on the risks to man and
nature of the gradual disappearance of darkness in the evening and at night as a result
of urbanization and other contemporary developments in the Netherlands.

Save the Night
Light pollution is the alteration of natural light levels in the outdoor environment due to manmade light sources.
The cost of lighting the world
Electric light is one of the greatest advances of the modern world, but, with the rise of light pollution, it has proved to be something of a mixed blessing.http://news.bbc.co.uk/1/hi/technology/6067900.stm
sunshine mirror
Viganella's problem is that it was built at the bottom of a very steep-sided Alpine valley, right up against the Swiss border.
The southern side of the valley is so sheer that on 11 November the sun disappears and does not reappear until 2 February.
Not one ray of sunlight falls on Viganella in the weeks in between.
"It's like Siberia," one woman said - and remember this is Italy.

Lighting risk to premature babies
Tests showed exposing baby mice to constant light keeps the master biological clock in their brains from developing properly.

Does Lighting Harm Trees?
Understanding tree response depends on the type of lamps used and the spectrum of radiation emitted, the intensity of that radiation, and the role of light in certain biological processes.

Outdoor Lighting and Crime: Is There a Connection?
Many people who have not had occasion to investigate the matter tend to assume that where crime is a concern, “the more light, the better”!
But the research that has been done to date has provided no reliable evidence that this so.

Lighting is still in the Dark Age
Light pollution is not just a waste of money, argues astronomer Darren Baskill in this week's Green Room. He says badly designed lighting is also having an impact on the environment and our health, as well as denying millions of people the right to enjoy the beauty of the night sky.
