'Great Smogs' and similar are noticeable because so many die sort of 'at the time', The same amount of pollution was being put into the air every day and breathed in by people, but much of the effects would not show for years if it was a kid.Just_a_fan wrote: ↑Mon Oct 11, 2021 10:52 pmThe 1952 "Great London Smog" is estimated to have killed as many as 12,000 people with ten times as many made seriously ill. That single event was worse than all of the nuclear disasters put together.
I am not talking about great smogs of a century ago, I mean maybe 1 day a week, but cumulative, and in the 1970s and probably later. I brought it up because although the smoke is not often discharged now, many of the combustion products still are, but without the smoke, are not noticeable.
London air was 'cleaned up' by the clean air act, which meant only 'smokeless fuel' could be burned within the city (and many other cities) but this meant that most of what would have become smoke in the city was burned (well roasted) off at the point it was extracted. Still breathed, but by people outside the city. (I suppose it was much less densely populated) and coke sent to the city.
