From the Guardian:
“Eco-friendly” LED streetlights produce even worse light pollution for insects than the traditional sodium bulbs they are replacing, a study has found.
The abundance of moth caterpillars in hedgerows by rural roads in England was 52% lower under LED lights and 41% lower under sodium lights when compared with nearby unlit areas.
In grass margins, moth caterpillar numbers near LEDs were a third lower than in unlit areas, whereas sodium lights had little effect on abundance. The white LED lights are more energy efficient but produce more blue light, say scientists, which is the colour predominantly seen by insects.
The environmental movement is destroying the environment.
