Cities are swapping traditional light bulbs for more energy-efficient brighter LEDs. The rise of these blue LEDs are creating problems for our night sky and our health.
I think a lot of it is also that we never bothered to use the switch to LED streetlights to fix the design issues with streetlights as a whole. So many of them are designed with no real care in their directionality. They are there to light downwards but make no efforts to minimise any directed up. A lot could be done to mitigate the effects with a better design focus to limit the lighting only to where required.
