Visual pollution occurs when you can see either physical damage to the environment, or pollution in the form of smog, litter, sludge, etc.
It was estimated that 4,000 people died and 100,000 were made ill
Great Smog happened in 1952.
My granddad :)
It no longer exists/happens but in the days when London houses used coal fires to heat homes, the coal smoke mixed with normal fog to produce what was called "smog" (smoke and fog). It was very thick and very bad for health. London no longer has "smog" events because it no longer allows chimneys to emit smoke.
Smoke and fog
The Great London Smog (SMoke + fOG) was the result of coal smoke from fired heating during an unusual cold period combining with the heavy fogs of London. Although smog was not uncommon in London this was an unprecedented event, it lasted from Friday 5 December to Tuesday 9 December 1952. The coal smoke contained sulfur dioxide ans a well as organic (coal tar) compounds which made the mixture acidic and resulted in breathing problems for many. About 4,000 people were known to have died as a result of the fog, this estimate could be considerably loweer than the actual number.
There hasn't been a smog in London for about 50 years.
smog was an issue that got so bad that in the 1950 and 1960 people died from breathing it. ( London England ) To reduce smog the American government brought in anti pollution regulations. Some of the most significant and noticeable govern the pollution output of automobiles.
London-type smog is caused mainly by air pollution due to combustion of coal and emission of sulfur dioxide and dust. London smog has humid, foggy, stagnant air.
'Snog' is a combination of the words smoke and fog. London used to be a huge manufacturing centre with coal-fired factories belching smoke into the atmosphere and most people heated their houses with coal fires in the days before central heating. The last great smog was in 1961 after the passing of the Clean Air Act which restricted people and businesses in the type of fuel that they could burn.
