The old low pressure sodium lights we had in the UK were great on this front. They were about as efficient as LEDs as well but the bulbs got too expensive to make, so the last factory making them in Europe closed down and they mostly disappeared quite quickly.
I reckon they should switch street lights over to monochromatic yellow LEDs, they’d look the same as the old lights and not affect insect populations so much. They’re good for astronomers too as the light is only one wavelength.
It would be a step in the right direction but the Tories would salivate at the idea of turning this election into a Brexit election. I suspect we’ve not heard the last of this and we’ll start re-aligning various policies with Europe on a case-by-case basis once the Tories are wandering the political wilderness, it’s the obvious thing for an incoming government to boost their economic credibility.
