Ben Drake: Hostess： Ben Drake: Hostess： Ben Drake: “Smog” comes from a combination of the words “smoke” and “fog”. It originated in Britain in the early 20th century, when smog was a severe problem.
Why was it so bad then
Well, Britain was one of the first industrial countries and factories and homes used lots of coal. When burnt, the coal produced harmful emissions which created lots of smog. In London, they also called the smog a “pea soup” because it was as thick as soup.
That sounds terrible! What problems did it cause
Smog caused many health issues and killed many people. The worst case happened in London in 1952.
Over a few days when the smog was particularly bad,
4, 000 deaths were recorded. Il was necessary to take immediate action. The UK govemment ordered people not to bum coal in their homes and forced factories to move away from city centres.

Smog is harmful to everyone, especially to children, old people, and those with heart or lung problems. We have to reduce smog a and improve air quality for everyone's health and wellbeing. We should replace coal with cleaner forms of energy, and we need to use new energy-efficient vehicles. We have the technology, but we must use and develop it.
Yes. Let's hope we can make some big cha anges. Thanks, Ben. ke: Thank you.
