Atmospheric pollution from factories day and night, video time lapse

[backofbeyond]

Your post, and particularly the very 'atmospheric' video, got me thinking about the whole problem of atmospheric pollution. I'm fortunate these days not to live in an area with poor air quality but that's not always been the case. Back when I was born, and for some years after that, London was plagued with recurrent 'super fogs' - smogs, where a particular set of atmospheric conditions and smoke from coal burning combined to form an almost unbreathable mix, sometimes for weeks on end. Here's a link to some archive film footage if you're interested in how bad things can get -

We moved out of the city and went to live in Ireland but that wasn't an option for everyone. Twenty years later a similar problem came to pass in Los Angeles but this time from vehicle emissions rather than coal fires. Both of these were resolved by legislation but if your livelihood comes from working in some of the factories in your video you might think the cure worse than the disease.
