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?

The lights are on - but is anybody home?

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
In order to find out appropriate lighting levels to create safe nighttime street environments, the nature of the relationships between pedestrian behaviour and lighting

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.
