London's Reaction to the Great Stink and the Great Smog

In the 1858 London's sewer systems led straight out into the River Thames, almost every home had their toilet's hooked up to the River and all of the cities waste would end up in the river going out to sea. However after intense summer heat this almost 'boiled' the river making a great stink. The smell was unbearable for most Londoners with some going miles out of their way to cross the river, the smell became so bad that people were able to smell it whilst walking through the streets of London making people feel very sick and even sometimes fall ill.
This led to the city designing new sewer systems transforming the London sewers with new pipes leading out to the Thames Estuary or to processing factories just outside the city.

In the winter of 1952, cold weather led to the people burning dirty coal in their chimney's as a way of heating their homes, with the winds being light the air near the ground was moist making it perfect conditions for radiation fog. On the 5th of december a thick fog settled over London bringing many dangerous side-affects. For the next 114 hours the green 'pea soup' fog hung over London interrupting many services within the city. The sulphar dioxide reacted within the smog creating in effect a very intense form of acid rain. 
In the first week 4,000 deaths were reported due to the inhalation of smog, 8,000 death followed in the next two months summing up the total deaths of the smog to 12,000 people.
