“Again ”
“Yes. My journey back to the clouds starts there. Remember not to waste or pollute me. I’m valuable.”

Extending and developing competencies
Focusing on culture
Water is not only essential for life, but is also important for human society. Let’s explore the role water plays in the development of cities.
1 Read the article and find out why water is important for cities.
If you look at a population map of any country in the world, you will see that most people live close to water. The world’s biggest cities are next to rivers, lakes or the sea. This isn’t an accident. We use water for all kinds of things in everyday life, and we also need it for agriculture and for trade.

In fact, water creates jobs and helps different industries to develop. At the end of the 18th century, water played a big role in the Industrial Revolution. Water powered the first machines in the clothes industry, such as Richard Arkwright’s spinning① machines. It also provided the first steam engines with steam. Thanks to rivers and oceans, businessmen could ship their goods overseas. The growing global trade created more jobs and provided more income for people. As a result, the cities that were close to water grew much larger.

By 2008, over half of the world’s population lived in cities. Nearly all of these cities are on the coast or by rivers or lakes. This is because cities need water for people’s homes, industry, business, tourism② and leisure activities. Throughout history, water helped create and develop cities. It is now our duty to make sure we don’t waste water or pollute it.
