Could it be your town
Jo is fifteen and lives in Parkville. When Jo’s grandparents first came to Parkville, it was a quiet village. They had a small house, close to fields and hills.
Parkville was near Arnwick, a city with 200,000 people. People from Parkville moved to Arnwick to find jobs, and they needed places to live. However, it was expensive to live in the city centre, so the government built flats outside the centre. Soon, Parkville became part of Arnwick, and Arnwick became a city with over a million people. Jo’s family lives in one of those flats. It is very crowded, and rubbish is also a problem.
The small local school in Parkville closed down five years ago, so Jo now has to go to a school in Arnwick with 2000 pupils. It takes an hour to get there by bus. There is a lot of traffic and pollution.
It is clear that Arnwick needs more schools,
buses and hospitals. It needs fresh air, clean water, and better public services. It also needs more police to protect its people. But to do all these things, it needs more money.
