Do you live in a city? Do you know how cities began? Long long ago, there were only a few thousand people in the world. These people moved from one place to another. They moved over the land, hunting animals for food.
No one knows how or when these people learned about growing food. But when they did, their lives changed. They did not have to move any more.
They could stay in one place and grow food there. People began to live near each other, so the first villages appeared. Many people came to work in the villages, and these villages became larger and larger.
Later people had machines. Life in the villages changed again. People built factories. More and more people lived near the factories, so the villages grew into cities. Some of them grew very big.
Today, it's strange that some people are moving back to small villages. Can you tell me why?
