Dear Sandy,

How are you? This week we did a project on the history of London.

My grandfather said that London in the 1950s was a terrible place to live because the air pollution was so bad. There were many factories and they caused a lot of smoke. This smoke caused heavy black fog in the sky. The people of London called this “smog”.

Sometimes the smog was so thick that people could not see at all. Taxis and buses could not go anywhere as it was too dangerous to drive. The smog was also harmful to people’s health, and some people found that it was difficult to breathe.

In 1965, the government made new laws about the pollution, and the air got much cleaner. Today it is clean and we never see smog in London.

Since the 1950s, people from all over the world have come to live in London. My grandfather says that this is one of the best changes—now he can eat food from India, China, Italy and Germany in his neighbourhood.

I like living in London today, and I am happy to have friends from all over the world.

Write back soon.
