#Insects trapped by a #streetlight. A 5 second footage.

Now imagine all the street lamps that are also turned on. Imagine all the light sources that are turned on, dusk to dawn. Not for 5 seconds. All-night.

How can this be so underrated?

This is a clear example of a major #impact caused by a "convenience", not a necessity.

Another excellent article by Paul Marchant and Paul Norman, demonstrating the non-detection of road (and criminal) safety benefits of road lighting nor in the recent replacements from sodium #HPS to #LED (in particular, #whiteLED ). It questions the high public investment in road lighting when that supposed benefit is not verified, & recalls the impacts of #artificiallight at night.
