Whilst we are all concerned about light pollution here in the UK it is recognised that this problem is a unwanted worldwide phenomena. It is a big talking point amongst astronomers in the USA. Here is a link to an essay about the problem.
It seems to me there is a recent increased worldwide awareness of the detrimental effects of light pollution. I suspect though that by the time it works its way up the action priority list many years will have past and the light pollution will have got many times worse.
However, let’s not get too depressed and remind imagers in particular there is a vast amount of useful and enjoyable astronomy that can be done from a light polluted site. So many people assume that because they can’t see the Milky Way or a 4th Mag star visually that nothing else is possible. I have poor light polluted skies here in SE Essex and still manage to image 18+ magnitude comets using my 315mm reflector.
